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.

The environmental monitoring system for radiation exposure due to light water reactor (LWR) nuclear power plant plume is described. This system, employing a NaI(Tl) scintillation detector with an exposure rate conversion circuit, has the capability of highly accurate evaluation of radiation exposure due to an LWR plume with 0.15 million R/yr (39 nC/kg.yr) overevaluation and 0.05 million R/yr (13 nC/kg.yr) underevaluation. Plume exposure is identified by combining the time variation property of the exposure rate with meteorological parameters. Outlines of the present system are described, including monitoring results obtained over a 98-day period by tentative system at an LWR site boundary.
