Developing a new regulatory framework for advanced reactors: Update on Part 53
White
The American Nuclear Society’s Risk-informed, Performance-based Principles and Policy Committee (RP3C) on March 29 held another presentation in its monthly Community of Practice (CoP) series. The presenter, Patrick White with the Nuclear Innovation Alliance (NIA), talked about the current status of efforts to develop a new regulatory framework for advanced reactors—known as 10 CFR Part 53 or simply Part 53. White serves as the research director of the NIA, where he leads their research as well as analysis-based stakeholder and policymaker engagement and education. White’s March 29 presentation is publicly available on YouTube and at ANS’s publication platform Nuclear Science and Technology Open Research (NSTOR).
RP3C chair N. Prasad Kadambi opened the CoP with brief introductory remarks about the RP3C before he welcomed White as the session’s presenter.
White covered three main topics: the history of the existing regulatory frameworks for new reactors, progress to date on the development of the Part 53 rule for advanced reactors, and the current status and next steps for the Part 53 rulemaking process.

Interaction between liquid metal flows and non-uniform magnetic fields occurs in certain regions of fusion power reactors such as the breeding blanket access pipes. Here, the resulting high MHD pressure drop leads to numerous design challenges. Therefore, in this paper we perform numerical simulations to analyze the effect of a non-uniform transverse magnetic field on a liquid metal flow in a straight electrically conducting pipe. In particular, we perform parametric analyses at different conductance ratios and magnetic interaction parameters to quantify their effect on MHD pressure drop in pipes. The results also help in establishing a range for the control parameters in which the flow transforms from a quasi-fully developed to a fully three-dimensional state.
