Which role uses PRA when providing basis for risk-informed Technical Specifications?

• A. Licensing / PRA Engineer
• B. Design Engineer
• C. Systems Engineer
• D. Nuclear Safety Engineer

Answer: (A)

Risk-informed Technical Specifications are grounded in probabilistic risk assessment results that justify regulatory licensing decisions. The Licensing Engineer, often pairing with PRA specialists, uses PRA findings to establish the basis for TS, translating risk significance into allowable outage times, surveillance requirements, and other limits that regulators accept. This role directly interfaces with the licensing process and ensures the plant’s TS reflect risk insights, not just deterministic criteria. Design Engineers and Systems Engineers focus on how equipment and systems function and are integrated, while Nuclear Safety Engineers analyze safety aspects, but the formal PRA-based justification for TS comes from the licensing side with PRA input.
