Which group uses PRA for incorporating the Maintenance Rule (10 CFR 50.65)?

• A. Systems Engineers
• B. Maintenance
• C. Design Engineers
• D. Operators

Answer: (A)

PRA-based insights determine which structures, systems, and components are most risk-significant, and that ranking guides how maintenance is planned and prioritized under the Maintenance Rule. The group that translates those PRA results into maintenance actions and schedules is the Systems Engineers. They oversee how the plant’s systems function together, interpret risk significance from PRA, and ensure maintenance decisions focus on reducing risk for the SSCs that matter most. Maintenance personnel carry out the work, but the decision about which items to prioritize, how often to inspect, and how to allocate resources is driven by systems engineering in light of PRA findings. Design engineers and Operators have other primary responsibilities—design changes and daily operations, respectively—so they don’t primarily drive risk-informed maintenance planning.
