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.

The first systematic study of the modulation process of traveling wave direct energy converter (TWDEC), an efficient energy recovery device for fast protons created in an advanced fusion, has been presented. The necessary conditions required for a practical TWDEC modulator were examined. The experimental investigation of modulation characteristics for half-wavelength and one-wavelength modulators was performed. In the one-wavelength modulator, the same effect as the half-wavelength modulator can be obtained by half modulation voltages of electrodes. The modulation effect is sensitive with the phase difference between two RF voltages of the one-wavelength modulator, which could be used for control of modulation effect with a fixed electrode structure.
