Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

Neutron-absorber materials are used in spent fuel pool (SFP) storage racks to increase storage capacity while maintaining criticality safety margins. Previously, the Electric Power Research Institute (EPRI) proposed a global, industrywide learning aging management program (i-LAMP) as an alternative monitoring program as part of an aging management program. This proposal, along with other EPRI work, was accepted as a concept to close the issued generic letter by the regulator. Since then, EPRI has been working with EPRI-member utilities around the world on data collection. Furthermore, recently, a utility removed two neutron-absorber panels from an operating SFP to meet a regulatory commitment made prior to the i-LAMP proposal. Because of their age and unique history, these panels provided a unique opportunity not only to analyze the conditions of the panels, but also to potentially bound i-LAMP. This paper presents i-LAMP development to date with a focus on BORAL analysis results for these two unique panels, pilot pools as case studies to demonstrate the i-LAMP implementation, and a proposal for a path forward.
