EPISODE 59: Chernobyl 40th Anniversary: Are Nuclear Power Plants Safe from A Cyber Attack?

In this episode, we commemorate the 40th anniversary of the Chernobyl disaster by asking a chilling modern question: Can a cyber attack cause a nuclear meltdown in 2026? Moving past the Hollywood tropes of ‘exploding reactors,’ we dive into the high-stakes world of OT (Operational Technology) security and critical infrastructure protection. We are joined by Oleg Illiashenko, an expert in nuclear cybersecurity, and Bec McKeown, a specialist in human factors and cognitive readiness, to explore the coordinated digital erosion of safety systems and the psychological ‘misfit’ that occurs when human decision-making collapses under pressure.
This isn’t a history lesson. It’s a deep dive into supply chain vulnerabilities, IT/OT convergence, and the uncomfortable truth that in a VUCA (Volatile, Uncertain, Complex, Ambiguous) crisis, the first thing to fail isn't the code, it's the human mind's ability to regulate stress.
Expect a masterclass in resilience engineering, safety-critical design, and why the battle for the future of nuclear safety is actually a battle for trustworthy data.
In This Episode, We Discuss:
The Anatomy of a Nuclear Cyber Attack: Why the most credible threat isn't a single hack, but the coordinated degradation of monitoring systems during a plant transient or grid instability.
From Chernobyl to Fukushima: How organisational silence, governance failures, and ignored ‘weak signals’ remain the primary human-factor risks in modern nuclear facilities.
The Action Bias Trap: Why the most effective incident response move is often a ‘purposeful pause,’ and how psychological safety allows experts to override failing procedures.
IT/OT Convergence & Fragility: How digitalisation and AI diagnostics improve safety while simultaneously expanding the attack surface through complex new failure modes.
Building Cognitive Readiness: Practical strategies for emotional regulation and ‘micro-resets’ to maintain shared alignment and decision quality during a high-consequence cyber event.
