Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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.

Basic regulatory values for tritium as well as other radionuclides are given in the Japanese “Law concerning Prevention from Radiation Hazards due to Radioisotopes”. In this law the regulatory standards on radiation safety are fundamentally based on the ICRP Recommendations. Annual limits on intake (ALIs), derived air concentrations (DACs) and release limits are provided in the law for tritium both in elemental and oxide forms. Detailed guides for radiation protection including radiation monitoring are stipulated in each establishment. Rules on health, safety and environment for tritium protection in Japan will be presented and discussed.
