Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

Taking shape: Fusion energy ecosystems built with public-private partnerships
It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.
Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.

Constellation Energy and the United States Department of Energy have established a partnership through the Light Water Reactor Sustainability Program to implement a pilot safety-related digital instrumentation and control (DI&C) upgrade for industry benefit. This DI&C upgrade replaces legacy analog reactor protection and emergency safety feature actuation systems (RPS/ESFAS) with modern digital systems. It also implements related main control room modifications. This upgrade is occurring at Constellation's Limerick Generating Station. This project is being performed in accordance with industry processes that have been adapted to better support DI&C upgrades. These processes include IP-ENG-001, Standard Design Process, NISP-EN-04, Standard Digital Engineering Process, and Electric Power Research Institute Report 3002011816, Digital Engineering Guide. This effort is a large-scale demonstration of the application of the alternate review process provided in NRC DI&C interim staff guidance (DI&C-ISG-06), Licensing Process. The alternate review process supports more timely NRC processing of license amendment requests associated with safety-related DI&C equipment modifications in operating plants and in new plants once they become operational. This panel discussion will facilitate a dialog with regard to engineering (both I&C and HFE), licensing, and project activities as well as lessons learned during project execution to date. Constellation is also developing a systematic modernization roadmap for safety-related reactor I&C systems with Limerick as part of this pilot. This panel discussion follows the presentation of three related papers on the Safety-Related I&C Upgrade Pilot Project during the Control Room Modernization Technical Session: (1) Conceptual and Design Phase Lessons Learned, (2) NUREG-0711 Process Development, Planning and Analysis Activities, and Lessons Learned, and (3) 3D Main Control Room Modeling.
