Compact Nuclear Power Systems Based on Particle Bed Reactors

摘要

Compact, low cost nuclear power systems with an extremely low radioactive inventory are described. These systems use the Particle Bed Reactor (PBR), in which HTGR particle fuel is contained in packed beds that are changed daily. The small diameter particle fuel (500 mu m) is directly cooled utilizing the large heat transfer area available (7.8 m sup 2 /liter), thus allowing high bed power densities. (ERA citation 11:047505)
