Stuxnet Scenario: Nuclear Engineering Corporation Crisis (2010)
Planning Resources
Scenario Details for IMs
Detailed Context
Organization Profile
Nuclear Engineering Corporation operates as private nuclear facility contractor founded in 1992, employing 350 specialized staff across enrichment operations (85 nuclear engineers, centrifuge technicians, enrichment specialists), nuclear safety and compliance (45 health physicists, radiation protection specialists, NRC compliance officers), industrial control systems and maintenance (60 Siemens SCADA engineers, control systems specialists, mechanical engineers), research and development (35 nuclear scientists, isotope production researchers), and support operations (125 including security, administration, logistics, quality assurance). The facility generates $280M annual revenue through commercial nuclear fuel enrichment services for civilian nuclear power plants ($220M revenue from 12 major utility contracts) and specialized isotope production for medical and research applications ($60M revenue serving pharmaceutical companies, university research programs, national laboratories).
The facility’s uranium enrichment operations use gas centrifuge cascade technology: uranium hexafluoride gas fed into high-speed centrifuges spinning at 90,000+ RPM (faster than jet engines), isotopic separation occurring through centrifugal force concentrating U-235 isotopes, cascaded centrifuge arrays progressively enriching uranium to required specifications (3-5% U-235 for commercial nuclear fuel, higher concentrations for research reactors), all controlled through Siemens S7-417 programmable logic controllers monitoring and adjusting centrifuge rotation speeds within 0.1% tolerance essential for safe operations. A typical enrichment cascade contains 164 centrifuges arranged in 18 stages operating continuously for 18-24 months; equipment precision requirements create extreme vulnerability to operational disruptions—centrifuge speeds deviating even 2-3% create mechanical stress causing bearing failure, rotor imbalance, catastrophic equipment damage.
Nuclear facility operations occur under extraordinary regulatory scrutiny: Nuclear Regulatory Commission (NRC) licensing requiring demonstration of safety culture, security protocols, and operational procedures protecting public health, International Atomic Energy Agency (IAEA) safeguards ensuring nuclear materials remain accountable and under continuous monitoring, facility security clearances for personnel handling special nuclear material, annual inspections verifying compliance with nuclear safety regulations and international non-proliferation commitments. Any security incident, operational anomaly, or regulatory non-compliance triggers immediate NRC reporting requirements, potential license suspension, and international safeguards investigation—creating environment where facility survival depends on maintaining absolute regulatory confidence in safety and security practices.
The facility’s business model depends on nuclear power industry trust in enrichment services security and reliability: commercial nuclear power plants operate on rigid fuel cycle schedules requiring delivery of enriched uranium at specific times and specifications, research institutions depend on isotope production meeting exact purity and activity requirements, and regulatory authorities expect nuclear facilities to maintain exemplary safety culture and security practices. Average customer contract value exceeds $18M annually across 8-12 year relationships; losing even single major utility customer through security incident or reliability concerns creates immediate revenue impact and generates industry concerns affecting new business across entire nuclear power sector.
June 2010 operational context intensifies crisis pressure: International Nuclear Security Summit scheduled in Washington DC for following week where facility planned to present enhanced security practices serving as industry model, major utility customer conducting renewal negotiation for $85M ten-year enrichment contract dependent on facility demonstrating operational excellence, and IAEA inspection team scheduled for quarterly safeguards verification in two weeks expecting routine compliance documentation. Discovery of sophisticated nation-state cyber weapon systematically manipulating centrifuge operations for months creates scenario where every stakeholder relationship and regulatory commitment faces simultaneous catastrophic disruption.
Key Assets and Operations
Nuclear facility safety and centrifuge operation precision represents fundamental requirement where cyber compromise creates direct radiological risk:
Centrifuge arrays operate under extreme physical conditions: rotors spinning at 90,000+ RPM (1,500 revolutions per second) creating forces exceeding 100,000 times gravity, ultra-high vacuum environments (10^-6 torr) required for isotopic separation, rotor temperatures maintained within 3°C tolerance for thermal stability, and vibration dampening systems isolating centrifuges from external disturbances. Siemens S7-417 PLCs monitor centrifuge parameters thousands of times per second, adjusting frequency converter drives controlling rotor speeds, triggering automatic shutdown sequences if parameters deviate outside safe tolerances, and providing operators real-time monitoring through SCADA displays showing normal green status indicators when equipment operates within specifications.
Stuxnet malware compromised this safety-critical control architecture at fundamental level: malicious code injected into PLC firmware modified centrifuge speed control algorithms, systematically alternating between dangerously high speeds (creating excessive mechanical stress on bearings and rotors) and suboptimal low speeds (disrupting enrichment process and thermal stability), while simultaneously manipulating SCADA monitoring to display normal operational parameters hiding physical damage from operators. This created unprecedented scenario where monitoring systems operators trusted to ensure nuclear safety provided false confidence while actual equipment experienced accelerated mechanical degradation—bearing failures, rotor imbalances, vacuum seal compromises—all occurring under cover of “normal operations” displays.
The physical consequences of cyber manipulation transcend equipment damage to create genuine radiological risk: centrifuge rotor failure at 90,000 RPM releases tremendous kinetic energy potentially compromising containment barriers, damaged vacuum seals allow uranium hexafluoride gas exposure to moisture creating corrosive and toxic hydrofluoric acid, cascade disruptions cause pressure imbalances potentially affecting multiple interconnected centrifuge stages. While no radiological release occurred during actual Stuxnet operations, the cyber weapon demonstrated capability to cause physical damage to nuclear facility equipment while concealing activities from safety monitoring systems—fundamentally undermining operational paradigm where nuclear safety depends on trust in instrumentation and control system accuracy.
Industrial control system security and air-gapped network architecture assumed to provide protection through physical isolation proven completely inadequate:
Nuclear facilities implement “defense in depth” security architecture specifically due to safety criticality: centrifuge control networks completely air-gapped with zero physical network connectivity to internet or external networks, dedicated SCADA workstations with disabled USB ports and optical drives preventing removable media, dual-authentication access controls for control room entry, and specialized Siemens Step 7 engineering workstations for PLC programming physically isolated in secure maintenance areas. Security philosophy assumed that network isolation plus physical access controls would prevent sophisticated adversaries from compromising systems controlling nuclear operations—even if motivated nation-state actors attempted attack, air-gapped architecture would make reaching isolated SCADA networks practically impossible.
Stuxnet completely invalidated this security paradigm through sophisticated understanding of operational workflows: attackers recognized that Siemens engineers contracted for centrifuge maintenance and updates required legitimate access to air-gapped SCADA systems via USB drives containing Step 7 project files, malware designed specifically to propagate through USB devices using multiple Windows zero-day exploits (MS10-046, MS10-061, MS08-067, LNK vulnerability) ensuring infection across diverse Windows environments these USB drives would encounter, infected Siemens Step 7 project files appearing completely legitimate to engineers transferring them between networked engineering workstations and air-gapped SCADA systems, and stolen digital certificates from Realtek and JMicron (legitimate hardware manufacturers) providing authentic code signatures that Windows trusted implicitly.
The attack exploited legitimate operational necessities rather than security weaknesses: centrifuge equipment required periodic firmware updates, performance tuning, and diagnostic procedures necessitating Siemens engineer access with project files on USB media—attempting to prevent this access would make nuclear facility inoperable. Air-gapped security assumed attackers couldn’t reach isolated networks, but operational reality required bridging air gaps through removable media during legitimate maintenance creating systematic vulnerability that sophisticated adversary understood and weaponized. Post-Stuxnet analysis revealed fundamental tension: operational technology (OT) environments require different security paradigms than information technology (IT) because OT operational continuity and safety requirements create constraints that IT security approaches don’t account for.
International nuclear security confidence and regulatory relationship management creates stakeholder crisis transcending technical remediation:
Nuclear Engineering Corporation operates within ecosystem of regulatory oversight, international safeguards, industry peer review, and public confidence scrutiny unique to nuclear industry. NRC licensing depends on facility demonstrating safety culture where problems surface immediately through comprehensive reporting rather than remaining hidden, IAEA safeguards require absolute transparency about nuclear material accountancy and security incidents affecting facility operations, commercial utility customers expect nuclear vendors to maintain exemplary security practices given sensitivity of nuclear fuel supply chain, and nuclear industry collectively operates under intense public scrutiny where single facility incident affects perception of entire sector.
Discovery that nation-state cyber weapon systematically manipulated centrifuge operations for months without detection creates multi-stakeholder crisis: NRC will question whether facility safety culture and monitoring capabilities adequately protect public health if sophisticated cyber attack remained undetected for extended period, IAEA safeguards inspectors will scrutinize whether nuclear material accountability systems can be trusted if control systems subject to manipulation without operator awareness, utility customers will evaluate whether to continue depending on enrichment facility whose industrial control systems proved vulnerable to nation-state compromise, and nuclear industry will face questions about whether civilian nuclear facilities can operate securely in era of nation-state cyber warfare.
Cultural Factors Contributing to Vulnerability
Air-gapped security paradigm assuming physical isolation provides adequate protection: Nuclear facilities in 2010 operated under security philosophy treating air-gapped industrial control networks as fundamentally secure through physical isolation—networks with zero internet connectivity, dedicated hardware, controlled physical access perceived as protected from sophisticated cyber threats. This assumption reflected broader industrial control system security culture where “security through obscurity” (proprietary Siemens protocols, specialized nuclear engineering knowledge, physical isolation) combined with physical access controls appeared sufficient protection for safety-critical operations. Stuxnet demonstrated that physical isolation alone inadequate when legitimate operational procedures require bridging air gaps through removable media during maintenance—creating systematic vulnerability that operational necessities made unavoidable.
Trust-based code signing validation without supply chain security awareness: Digital certificate architecture in 2010 assumed that certificates issued by trusted certificate authorities and used by legitimate hardware manufacturers provided sufficient proof of software authenticity. Stuxnet’s stolen certificates from Realtek and JMicron revealed supply chain vulnerability where adversaries compromising legitimate manufacturers’ certificate signing infrastructure could create malicious software that operating systems and security software would trust implicitly. This supply chain attack vector predated broad industry awareness of software supply chain risks—most organizations assumed that digitally signed software from recognized vendors could be trusted without independent integrity verification, creating environment where stolen legitimate certificates provided powerful attack capability.
Stakeholder Perspectives and Conflicts
Dr. Helen Carter — Nuclear Safety Director, Regulatory Coordination Lead, Former NRC Official - Role & Background: 22-year nuclear industry veteran including 12 years as NRC inspector before joining Nuclear Engineering Corporation in 2006 as Nuclear Safety Director, leads 45-person safety and compliance organization responsible for NRC licensing, IAEA safeguards coordination, radiation protection, and safety culture, personally developed facility safety culture program cited as industry model, maintains close relationships with NRC regional office and IAEA safeguards division, scheduled to present facility security best practices at International Nuclear Security Summit following week - Immediate Crisis: Friday afternoon June 18, 2010 discovery that sophisticated cyber weapon has been systematically manipulating centrifuge control systems for estimated 4-6 months—forensic investigation reveals Stuxnet malware targeted Siemens S7-417 PLCs controlling centrifuge rotation speeds, alternated between dangerously high and low speeds causing mechanical stress and bearing damage, simultaneously manipulated monitoring systems displaying normal operations while actual equipment degraded, all while she was preparing presentation about facility exemplary security culture for international nuclear security conference - Impossible Choice: Immediately report cyber weapon discovery to NRC as required by license conditions, disclose to IAEA as safeguards incident, cancel International Nuclear Security Summit presentation, and coordinate comprehensive facility investigation accepting months-long operational suspension (preserving nuclear regulatory transparency and safety culture BUT destroying facility operational credibility, triggering intense international scrutiny, and potentially forcing business closure if industry confidence collapses), OR Coordinate classified investigation with federal intelligence agencies treating this as national security matter with delayed NRC/IAEA reporting, continue controlled operations while verifying safety under classified oversight, present modified security summit content avoiding disclosure (maintaining facility operations and industry confidence BUT violating NRC reporting requirements, potentially compromising nuclear safety if continued cyber manipulation occurs, and facing catastrophic liability if incident later revealed through security research or accident investigation) - Conflicting Pressures: Nuclear safety professional ethics and NRC regulatory culture demand immediate comprehensive disclosure when safety systems potentially compromised—operating philosophy in nuclear industry that problems surface immediately through reporting rather than remaining hidden until catastrophic failure. National security considerations suggest treating nation-state cyber weapon as classified intelligence matter requiring coordination with FBI, NSA, DHS rather than public NRC disclosure creating headlines about nuclear facility vulnerability. Personal professional reputation protection argues for complete transparency documenting she reported immediately upon discovery—but disclosure destroying facility she’s worked to build creates profound personal and professional loss. - Hidden Agenda: Helen recognizes that this cyber weapon discovery undermines the safety culture philosophy she’s championed throughout career. She advocated internationally for transparency and reporting culture as foundation of nuclear safety—but now faces scenario where transparency likely destroys facility while concealment preserves operations. She scheduled to present at nuclear security summit about facility’s exemplary practices, including monitoring and safety systems that failed to detect six months of centrifuge manipulation. The professional humiliation of presenting safety culture model that proved inadequate against nation-state threat devastates her beyond immediate facility crisis—questioning whether nuclear industry can operate safely in cyber warfare era and whether her career safety advocacy based on false assumptions about control system integrity.
Thomas Mueller — Control Systems Specialist, Siemens SCADA Engineering Lead - Role & Background: 16-year industrial automation career including 8 years at Siemens as PLC applications engineer before joining Nuclear Engineering Corporation in 2008 as Control Systems Specialist, leads Siemens SCADA engineering and maintenance for centrifuge control systems, maintains facility Siemens Step 7 engineering workstations and manages contractor coordination for PLC firmware updates, expert in S7-417 controller programming and centrifuge frequency converter drive integration - Immediate Crisis: Investigation of unusual centrifuge behavior anomalies discovered Stuxnet malware embedded in PLC firmware—analysis reveals adversary possessed extraordinarily detailed knowledge of proprietary Siemens Step 7 programming, exact S7-417 memory layouts, specific centrifuge frequency converter models, and precise operational parameters unique to uranium enrichment, indicating months of intelligence gathering and reverse engineering that should have been impossible for systems operating in classified nuclear facility - Impossible Choice: Collaborate with federal investigators and Siemens security teams for comprehensive forensic analysis documenting attack sophistication and intelligence gathering sources (providing critical threat intelligence BUT requiring extensive facility downtime, revealing potential insider access or Siemens supply chain compromise, and acknowledging security inadequacy of air-gapped architecture he designed), OR Implement emergency control system hardening and monitoring allowing continued operations under enhanced surveillance without full forensic investigation (preserving facility operations BUT potentially missing additional persistent access mechanisms, leaving nation-state adversaries’ intelligence sources unidentified, and creating ongoing vulnerability) - Conflicting Pressures: Industrial control system security best practices demand comprehensive forensic investigation before trusting compromised systems—but nuclear facility operational requirements create pressure to minimize downtime and maintain fuel delivery commitments. Responsibility to Siemens and broader industrial control security community suggests sharing detailed attack analysis for collective defense—but facility confidentiality and potential classification by intelligence agencies may prevent disclosure. Personal expertise protection argues documenting that attack sophistication exceeded any reasonable industrial security expectations—but being control systems lead when nation-state adversary compromised systems he maintained threatens professional reputation.
Rachel Kim — Security Manager, Industrial Cybersecurity Program Lead - Role & Background: 14-year cybersecurity career transitioning from IT security to operational technology security, joined Nuclear Engineering Corporation in 2009 to build industrial cybersecurity program, leads 12-person team responsible for SCADA network security, physical access controls, and emerging OT/IT convergence challenges, struggles with applying traditional IT security to OT environments with fundamentally different requirements - Immediate Crisis: Stuxnet investigation reveals complete failure of air-gapped security paradigm she defended as adequate protection for nuclear facility—USB-based propagation through legitimate maintenance workflows bypassed network isolation, traditional IT security tools (antivirus, firewalls, intrusion detection) completely ineffective against zero-day exploits and sophisticated nation-state tradecraft, and operational technology requirements preventing implementation of IT security best practices created systematic vulnerabilities she didn’t fully understand - Impossible Choice: Advocate for comprehensive OT security transformation implementing defense-in-depth beyond air-gaps (application whitelisting, network segmentation, behavioral monitoring, USB controls) acknowledging previous security inadequacy BUT requiring multi-million dollar investment, extended operational disruptions, and fundamental changes to maintenance workflows that facility may not accept, OR Implement targeted remediation addressing specific Stuxnet vulnerabilities allowing continued operations with minimal disruption BUT maintaining fundamentally inadequate security posture against future nation-state threats and leaving facility exposed to evolving cyber weapon capabilities - Hidden Agenda: Rachel privately devastated by realization that her IT security background inadequately prepared her for operational technology security challenges. She advocated for air-gapped architecture as sufficient protection, opposed expensive OT security proposals as unnecessary for physically isolated systems, and assured leadership that nuclear facility cybersecurity was adequate. Now facing scenario where nation-state adversary completely bypassed security architecture she designed, demonstrating that IT security expertise doesn’t translate to OT environments. Beyond immediate crisis, questioning whether she should continue in OT security role or acknowledge that industrial cybersecurity requires fundamentally different expertise than traditional IT security she spent career developing.
Mark Johnson — Operations Supervisor, Centrifuge Operations and Monitoring Lead - Role & Background: 19-year nuclear operations career including US Navy nuclear power program before joining Nuclear Engineering Corporation in 2003 as centrifuge technician, promoted to Operations Supervisor in 2007 leading 24-person operations team across three shifts, responsible for monitoring SCADA displays and responding to operational alarms, maintains absolute confidence in instrumentation and monitoring systems as foundation of nuclear safety culture - Immediate Crisis: Learning that centrifuge monitoring systems he trusted completely for nuclear safety were systematically compromised—SCADA displays showed green “normal operations” status while actual centrifuge speeds fluctuated dangerously, operators made decisions about facility safety based on false information provided by manipulated monitoring systems, and equipment damage occurred for months while he and operations team maintained confidence that systems operated within safe parameters based on instrumentation they were trained to trust absolutely - Impossible Choice: Accept that monitoring and control systems cannot be trusted and implement extensive manual validation and independent measurement (preserving operator safety awareness BUT reducing operational efficiency, requiring additional staffing, and fundamentally changing operational paradigm where nuclear safety depends on automated monitoring), OR Restore confidence in control systems after comprehensive security remediation claiming threat eliminated (allowing efficient operations BUT requiring operators to trust systems that proved vulnerable to manipulation, creating psychological burden of operating with uncertainty about instrumentation accuracy) - Hidden Agenda: Mark’s entire nuclear operations philosophy built on absolute confidence in instrumentation—Navy nuclear training emphasized trusting your instruments, following procedures, maintaining confidence in engineered safety systems. Stuxnet shattered this foundational assumption by demonstrating that sophisticated adversaries can manipulate instrumentation creating complete disconnect between displayed parameters and actual conditions. Beyond technical crisis, facing existential question about how nuclear operations function when operators cannot fully trust monitoring systems. If SCADA displays can be manipulated to show “normal” while equipment fails, how does operations supervisor ensure safety? This threatens core identity as nuclear professional where safety culture depends on instruments providing accurate reality.
Why This Matters — The Layered Crisis
You’re not just managing malware removal—you’re responding to nation-state cyber weapon demonstrating unprecedented capabilities targeting critical infrastructure for physical sabotage. Traditional malware response focuses on removing infections, protecting data, and restoring operations—but Stuxnet represents fundamental shift to cyber weapons achieving physical world objectives through manipulation of industrial control systems. Four zero-day Windows exploits plus Siemens SCADA vulnerability combined with stolen code signing certificates from legitimate manufacturers indicate nation-state development resources exceeding tens of millions of dollars. Systematic centrifuge manipulation alternating speeds to cause mechanical stress while hiding activities from monitoring systems demonstrates cyber-physical attack capabilities where digital compromise creates kinetic destruction. This isn’t information theft or operational disruption—this is cyber warfare targeting critical infrastructure with precision sabotage objectives.
You’re not just protecting computer networks—you’re safeguarding nuclear facility safety where cyber compromise creates direct radiological risk and undermines fundamental operational paradigm. Nuclear operations depend absolutely on instrumentation and control system accuracy providing operators truthful information about equipment status and safety parameters. When monitoring systems display “normal operations” while actual centrifuge speeds deviate dangerously, the foundational assumption enabling safe nuclear operations collapses. Operators cannot ensure safety if instruments lie—creating existential crisis for nuclear safety culture where transparency and trust in monitoring systems represent philosophical bedrock. Beyond immediate cyber incident, confronting whether nuclear facilities can operate safely in era where nation-state adversaries possess capabilities to manipulate safety-critical control systems while concealing activities from operators and regulators.
You’re not just investigating security incident—you’re navigating classified intelligence operation with international nuclear security and regulatory implications. Nation-state cyber weapon targeting nuclear enrichment facility transcends corporate incident response into national security, international relations, and intelligence operations territory. FBI counterintelligence jurisdiction overlaps with NRC regulatory authority, IAEA safeguards obligations, and Department of Energy nuclear security coordination—creating complex multi-agency stakeholder environment where every disclosure decision carries geopolitical implications. Facility operates under NRC license requiring immediate safety-related incident reporting, but intelligence community may classify investigation restricting disclosure. Commercial utility customers deserve notification that fuel supplier experienced nation-state compromise, but premature disclosure could trigger international nuclear security crisis affecting entire civilian nuclear power industry.
IM Facilitation Notes
Emphasize nation-state sophistication—4 zero-days plus stolen certificates representing tens of millions in development costs: Players often underestimate Stuxnet capabilities without understanding resource implications. Help players grasp nation-state scale: zero-day Windows exploits worth $100,000-500,000 each on black market (four exploits = $2M+ just for vulnerability knowledge), Siemens SCADA zero-day requiring months of reverse engineering proprietary industrial protocols, supply chain compromise stealing legitimate manufacturer certificates indicating persistent access to Realtek and JMicron signing infrastructure, detailed intelligence about Iranian nuclear facilities’ exact PLC models and configurations. This sophistication level definitively indicates state-sponsored development—no cybercriminal organization possesses these resources or motivations. Ask: “When adversary can deploy four zero-day exploits simultaneously, what does that tell you about their capabilities and resources? How does fighting nation-state threat differ from defending against cybercriminals?”
Surface air-gapped security paradigm failure—operational necessities creating systematic vulnerability: Players and IMs often assume air-gapped networks provide strong security without understanding operational reality. Help players recognize tension: nuclear facilities require air-gapped SCADA networks for safety criticality, but centrifuge equipment needs periodic firmware updates, performance tuning, and diagnostic maintenance necessitating Siemens engineer access with USB media containing project files. Attempting to prevent contractor access makes facility inoperable—but allowing USB media creates attack vector that Stuxnet weaponized. Guide discussion toward recognizing that “air-gap” represents security theory that operational practice undermines, and that OT security requires different paradigm than IT security isolation approaches. Ask: “If nuclear safety requires air-gapped controls, but operations require contractor access with USB drives, how do you achieve security? What does ‘defense in depth’ mean when perimeter isolation proves inadequate?”
Connect to cyber-physical convergence—digital compromise achieving kinetic destruction: Players often treat cybersecurity as protecting data and IT systems without fully grasping physical world impact. Stuxnet demonstrates cyber-physical weapon: manipulating PLC code controlling centrifuge frequency converters created physical mechanical stress on equipment spinning at 90,000 RPM, systematic speed variations caused bearing failures and rotor imbalances worth millions in equipment damage, monitoring system manipulation concealed destruction from operators while physical sabotage occurred. This represents fundamental shift from cyber attacks affecting information (data theft, website defacement, ransomware) to cyber weapons causing physical destruction of critical infrastructure equipment. Ask: “When centrifuge rotors fail catastrophically because malicious code manipulated their spin speeds, is that a cybersecurity incident or a physical attack? How does responding to cyber-physical weapons differ from traditional incident response?”
Guide attribution discussion—technical forensics plus geopolitical analysis: Attribution of nation-state cyber attacks combines technical indicators with strategic assessment. Technical evidence: code sophistication, zero-day exploitation capability, supply chain compromise resources, detailed target intelligence. Strategic evidence: geopolitical motivations, timing aligned with international pressure on Iranian nuclear program, targeting patterns focusing on specific centrifuge configurations used in Iranian facilities. Intelligence community attribution requires high confidence addressing “who benefits?” questions beyond just technical capability assessment. Help players understand attribution as intelligence assessment with confidence levels (low/medium/high) rather than definitive proof, and that attribution affects response options ranging from diplomatic pressure to potential military responses. Ask: “What evidence would convince you this was nation-state attack? How confident can you be in attribution? What happens if you’re wrong about attribution and accuse wrong country?”
Discuss regulatory vs. intelligence reporting dilemma—NRC transparency conflicting with classified investigation: Nuclear facilities face unique regulatory environment where NRC license requires immediate reporting of safety-related incidents and security events, but nation-state cyber weapon creates national security equities where intelligence community may classify investigation restricting disclosure. Surface genuine tension: NRC reporting supports safety culture and regulatory transparency that nuclear industry depends upon, but classified national security investigation may determine that public disclosure would benefit adversaries or affect ongoing intelligence operations. Neither option clearly “correct”—players must navigate conflicting obligations to regulator, intelligence community, commercial customers, and industry. Ask: “If NRC requires immediate reporting but FBI classifies investigation, which obligation takes priority? How do you maintain nuclear safety culture transparency while protecting national security interests?”
Use stakeholder NPCs to surface impossible nuclear safety dilemmas: Dr. Helen Carter facing regulatory reporting vs. national security classification, Thomas Mueller confronting control systems expertise inadequacy, Rachel Kim recognizing IT/OT security gap, and Mark Johnson questioning trust in instrumentation represent genuinely impossible situations. Resist providing single “correct” answer—instead use NPCs to surface conflicting pressures. When players propose solutions, respond with stakeholder perspectives showing complexity: Helen explains NRC expects immediate disclosure, but intelligence officer indicates classification necessity; Thomas describes forensic investigation requiring facility shutdown, but operations demands maintaining fuel delivery commitments; Rachel advocates comprehensive OT security transformation, but CFO explains multi-million dollar cost threatens facility viability. Force players to prioritize values (safety vs. operations, transparency vs. security, regulatory compliance vs. intelligence cooperation) rather than solving with purely technical solution.
Hook

Common IM Facilitation Challenges:
If Nation-State Sophistication Is Underestimated:
“Thomas explains that this malware used FOUR zero-day exploits - worth millions of dollars each on the black market - and stolen certificates from legitimate companies like Realtek and JMicron. The attackers knew exactly which Siemens PLC models you use, the specific centrifuge configurations, and how to hide their manipulation from monitoring systems. This level of sophistication indicates months of intelligence gathering and resources only nation-states possess. How does this change your threat model and response approach?”
If Air-Gapped Security Assumptions Are Unchallenged:
“Dr. Carter reminds you that these systems are air-gapped - completely isolated from the internet with no network connections. Yet the malware still reached them through USB drives used for legitimate maintenance and updates. The ‘air-gap’ you trusted for nuclear security has been completely bypassed. How do you rethink industrial security when your fundamental isolation assumption is proven false?”
If Physical World Consequences Are Overlooked:
“Operations Supervisor Mark reports that the malware has been systematically manipulating centrifuge speeds for weeks - spinning them too fast, then too slow, causing mechanical stress and physical damage while monitoring systems showed everything was normal. This isn’t just data theft or espionage. This is a cyber weapon causing physical destruction of nuclear facility equipment. How does this physical impact change your understanding of cybersecurity threats?”
