RP3C Community of Practice’s fifth anniversary
In February, the Community of Practice (CoP) webinar series, hosted by the American Nuclear Society Standards Board’s Risk-informed, Performance-based Principles and Policies Committee (RP3C), celebrated its fifth anniversary. Like so many online events, these CoPs brought people together at a time when interacting with others became challenging in early 2020. Since the kickoff CoP, which highlighted the impact that systems engineering has on the design of NuScale’s small modular reactor, the last Friday of most months has featured a new speaker leading a discussion on the use of risk-informed, performance-based (RIPB) thinking in the nuclear industry. Providing a venue to convene for people within ANS and those who found their way online by another route, CoPs are an opportunity for the community to receive answers to their burning questions about the subject at hand. With 50–100 active online participants most months, the conversation is always lively, and knowledge flows freely.

A high sensitivity radionuclide analysis system has been developed. An automated system employs an ion exchange method to concentrate target nuclides in reactor coolant water. The system consists of sample treatment equipment and an automatic sample changer in conjunction with a multichannel gamma-ray spectrum analyzer. The sample treatment equipment performs sampling, filtration, sample volume selection, and ion exchange. These four processes are fully automated. Performance tests show that the lowest analysis level is 10-6 μCi/ml of 131I within 10% reproducibility. The processing time from sampling to ion exchange is within 10 min for samples <100 ml.
