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.

An entirely new process was discovered starting from M-doped glow discharge polymer (GDP) deposited by plasma polymerization1 (where M = Si or Ti) to make M-oxide shells. This process utilizing Si-GDP was developed to make large, uniform, thick-walled glass shells which are suitable for use in cryogenic layering experiments at LLNL and are unobtainable by the routinely utilized drop-tower method. We have found that in addition to controlling the geometry, the permeability and opacity may be controllable over very wide ranges by varying the processing conditions. Preliminary tests to determine the strength of SiO2 glass shells made by this process are consistent with that expected of pure silica glass.
