BWRX-300 SMR passes U.K. regulatory milestone
GE Vernova Hitachi Nuclear Energy’s BWRX-300 small modular reactor has completed the second step of the generic design assessment (GDA) process in the United Kingdom. In this step, the U.K. Office for Nuclear Regulation, the Environment Agency, and Natural Resources Wales did not identify “any fundamental safety, security safeguard or environmental protection shortfalls with the design of the BWRX-300.” Step 1 was completed in December 2024.

Assemblies have been built for measuring gamma rays from coal following the capture of neutrons from 252Cf. Sources of sizes to 60 μg of calcium 1.4 × 108 n/s were used. Paraffin moderated the fast neutrons, and beryllium metal was useful as a reflector. The gamma-ray spectrum from a Ge(Li) detector showed that the line intensities of a number of elements (e.g., hydrogen, iron, sulfur, and silicon) could be used to determine concentrations. The aim was to explore possible application in planned coal conversion plants.
