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.

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.

The paper gives a brief overview of benchmark experiments that have been performed and are being performed at the Russian Research Centre "Kurchatov Institutes" (RRC KIs), satisfy requirements of the International Criticality Safety Benchmark Evaluation Project (ICSBEP), and have been published or will be published in the "International Handbook of Evaluated Criticality Safety Benchmark Experiments."These experiments include critical experiments in water-moderated facilities pertaining to substantiation of reactor physics for VVER-type light water reactors with uranium enrichments varying from natural uranium to ~6.5%; in heterogeneous critical assemblies with a widely varying uranium enrichment (from 5 to 96%) for small nuclear power systems of various applications; in critical assemblies with a uranyl sulfate solution core; and in critical assemblies simulating peculiarities of high-temperature gas-cooled reactors (HTGR), RBMK physics, etc.A list of critical assemblies currently in operation at RRC KI is given. Future experimental programs are briefly described; their implementation, if based on the ICSBEP requirements, will be useful for the international community.Using RRC KI as an example, it is demonstrated that Russian nuclear centers maintain capabilities for carrying out a wide range of new critical experiments, including international cooperation in this area.
