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 NaI(Tl)-based in-line enrichment monitor has been developed for the gas-phase UF6 feed stream of an enrichment plant to provide real-time material-accountancy and/or containment-surveillance data. The method has produced assay results that are independent of operating UF6 pressure, with an assay accuracy of better than 1% (1σ) relative over the range of UF6 enrichments of 0.72 to 5.4 at.%. For 1.0%-enriched UF6 at 700 Torr, a 0.74% relative precision was obtained for a 1000-s counting time. As a result of these measurements, an in-line gas-phase enrichment monitor has been installed in the Paducah-product feed line of the Oak Ridge Gaseous Diffusion Plant for field test and evaluation.
