Argonne’s METL gears up to test more sodium fast reactor components
Argonne National Laboratory has successfully swapped out an aging cold trap in the sodium test loop called METL (Mechanisms Engineering Test Loop), the Department of Energy announced April 23. The upgrade is the first of its kind in the United States in more than 30 years, according to the DOE, and will help test components and operations for the sodium-cooled fast reactors being developed now.

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.
