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.

The first attempt at developing chopped W fiber-reinforced W (Wf/W) composites without an engineered interface or inter-phase employing hot isostatic pressing (HIP) has been made in order to study the feasibility of the powder metallurgy (PM) fabrication methodology. Micro-structures and flexural properties of sintered compacts have been examined by an optical microscope (OM), a scanning electron microscope (SEM) equipped with an electron back scattering diffraction (EBSD) instrument and three-point bending (3PB) tests. There are some chrysan-themum-like grains around each fiber in W matrices. Mechanical properties, namely strength and pseudo-plasticity, of the sintered compacts are far from satisfactory. Abnormal grain growth does not seem to have a preferential growing direction according to EBSD results. Possible causes for the abnormal grain growth and further mechanical property optimizations are hereby presented.
