What’s the most difficult question you’ve been asked as a maintenance instructor?
Blye Widmar
"Where are the prints?!"
This was the final question in an onslaught of verbal feedback, comments, and critiques I received from my students back in 2019. I had two years of instructor experience and was teaching a class that had been meticulously rehearsed in preparation for an accreditation visit. I knew the training material well and transferred that knowledge effectively enough for all the students to pass the class. As we wrapped up, I asked the students how they felt about my first big system-level class, and they did not hold back.
“Why was the exam from memory when we don’t work from memory in the plant?” “Why didn’t we refer to the vendor documents?” “Why didn’t we practice more on the mock-up?” And so on.

The multiyear program entitled Nondestructive Evaluation Reliability for In-Service Inspection of Light Water Reactors, sponsored by the U.S. Nuclear Regulatory Commission, is being conducted at the Pacific Northwest Laboratory. The goals of the program are to determine the reliability of current in-service inspection of pressure boundary systems and components and to develop recommendations that can ensure a suitably high inspection reliability. The long-term objective is to develop recommendations for improved in-service inspections. In meeting program objectives, a risk-based method has been developed to guide the development of inspection plans. The method uses results of probabilistic risk assessment and failure modes and effects analysis techniques to identify and prioritize the most risk-important systems and components for inspection at nuclear power plants. The Surry Nuclear Power Station Unit I was selected for demonstrating the methodology. The specific system addressed in this study was the high-pressure injection/recirculation (HPI/R) system. The results provide a risk-based ranking of components within the HPI/R system, which can be used to guide the development of improved inspection plans for nuclear power plants. This work will subsequently be used in supporting the revisions of the American Society of Mechanical Engineers’ codes and standards.
