Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

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.

Currently a joint experimental program is performed on the RUDI injector at the TEXTOR tokamak in a collaboration between the Budker Institute of Nuclear Physics SB RAS and the Research Center Juelich (Forschungszentrum Juelich GmbH). The diagnostic injector RUDI is used for charge-exchange recombination spectroscopy (CXRS) diagnostic at the tokamak TEXTOR. Since the spatial resolution and CXRS signal level depend on diagnostic beam divergence and beam full-energy component current density, respectively, these beam parameters should be controlled to provide stable CXRS measurements. The beam density distribution, the angular divergence and the species composition, can be measured optically by spectroscopic means. The absence of perturbations to the beam investigated is one of the main advantages of optical diagnostics.
