STEAM COOLED POWER REACTOR EVALUATION MIXED SPECTRUM SUPERHEATER

摘要

The Mixed Spectrum Superheater (MSS) is a nuclear reactor contained within a pressure vessel in which both boiling of water and superheating of the resulting steam takes place. The reactor core consists of four annular regions: an inner unmoderated superheating region, an inner unmoderated buffer region, an outer moderated buffer region and a boiling region which is very similar to that in a standard boiling water core.
