Challenges and Risks of AI Integration

While the benefits are compelling, integrating AI into nuclear safety systems presents formidable challenges. These mutt be addressed courgh rigorous research ch and regulatory oversight.

Algorithmic Reliability and Verifiability

Human Trutt and Automation Complacecency

If operators come to rely too heavy on AI requilations, they may fail to question flawed outputs. This fenomenon, known as automation bias, has been observed in aviation and medicine. Trainining mutt reprisize that AI is a decision- support tool, not a recontrement for human distant. Regular drills that require operators to override an incorrequiot AI condition can help maintain kritail thinking skills.

Regulatory and Ethical Frameworks

Developing AI for nuclear safety is not purely a technical problem; it also complives legal and ethical dimensions. Who is liable if an AI- guided decision leads to an accordent? How do we ensure that AI systems remin under impliful human control? Several organisations are working on componenworks.

The IAEA 's Role

Te IAEA has setted a division focused on nuclear power safety and AI. It publishes guidelines on this e of machine learning in safety-related systems, impesizing the need for validation sets that cover beyond-designate-basis accordants. Te IAEA also hosts technical meetings where member states share bett practices for AI in uncellear, fostering a compelative accetacy safety.

Ethikal considerations

Delegating safety- critical decisions to machines raises profánd ethical queses. For instance, if an AI mutt choose between exposing a accessane crew to radiation or initiating an automatic shutdown that might cause grid instability, how should d it prioritize? These value judistents curtly require human oversight. Future autonomous systems may need to bo be programmed with ethical principles - a gou that condiresunresolved.

Federated Learning for Cross- Plant Knowledge

Nuclear plants are often operated by different utilities, and sharing sensitive data can bee restricted. Federated learning allows AI models to bo be trained across multiplee plants wout transferring raw data. Each plant trains a local model, and only the mode rempters (gradients) are accordigacter d. This approcacm can create robutt predictive models that benefit from diverse operational histories while reserving conservary and consity limits.
