Division Spotlight
Mathematics & Computation
Division members promote the advancement of mathematical and computational methods for solving problems arising in all disciplines encompassed by the Society. They place particular emphasis on numerical techniques for efficient computer applications to aid in the dissemination, integration, and proper use of computer codes, including preparation of computational benchmark and development of standards for computing practices, and to encourage the development on new computer codes and broaden their use.

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 long-term (>1000 years) hazard of radioactive waste emplaced in a geologic repository could be reduced by separating the most significant long-lived radionuclides and transmitting them to stable products by bombardment with neutrons in power reactors. A cost-risk-benefit analysis of this concept shows that, while it is technically feasible to partition and transmute the principal long-lived constituents, there are no cost-risk-benefit incentives that can be identified. The cost of partitioning and transmuting the actinide elements is estimated to be $9.2 million/ GW(electric). yr [1.28 mill/kWh(electric)]. The shortterm radiological risk is increased by 0.003 health-effect/GW(electric). yr, and the expected long-term benefit (i.e., incremental risk reduction from a repository) is 0.06 health-effect/GW(electric ).yr integrated over 1 million years. The latter is only ∼0.001% of the health effects expected from natural background radiation and is equivalent to $32 400 per person-rem saved. If nonradio logical risks are included, the short-term risk actually exceeds the long-term benefits.
