To identify a nuclear fault_______ .

• A. Rely on manual inspection only
• B. Use only initial built-in test system fault detection data
• C. Use external fault reports
• D. Ignore fault data

Answer: (B)

Starting with the built-in test system’s fault detection data is the most reliable way to identify a nuclear fault because this data comes directly from the system’s monitoring logic and provides standardized, objective fault codes and diagnostic information. It offers a fast, non-subjective starting point that highlights where a problem is likely located, even if the fault isn’t obvious through visual inspection. Relying on manual inspection alone can miss hidden or intermittent faults, and external fault reports, while useful for context, may not reflect the current condition or may arrive too late to prevent issues. Ignoring fault data is unsafe. Using the initial built-in test system fault detection data gives you a solid, repeatable basis to diagnose and then verify with additional checks as needed.
