What is the public risk level for this reactor?

• A. High risk.
• B. Negligible risk to the public due to design.
• C. Moderate risk.
• D. Severe risk.

Answer: (B)

Public risk level is about how much radiation exposure the public could receive if something goes wrong. Modern reactors are built with defense-in-depth: a robust containment, multiple redundant safety systems, automatic shutdown capability, and sometimes passive cooling that can operate without power. These features limit both the chance of an accident releasing radioactivity and the potential dose to people outside the plant. That combination makes the public risk level negligible due to design—the design itself keeps releases and doses far below regulatory concerns. The other risk levels would imply outcomes that these safety features are specifically designed to prevent, so they don’t fit the reality of how these reactors are engineered to protect the public.
