THERMIONIC FAST-FISSION CONVERSION REACTOR Russian patent published in 2000 - IPC

FIELD: nuclear power engineering; space-mounted power plants. SUBSTANCE: reactor core built up of thermionic fuel assemblies has external shells of the latter made of material containing resonance-tuned absorbers of thermal neutrons or otherwise shells are covered with material incorporating resonance-tuned absorbers of thermal neutrons. Materials containing resonance-tuned absorbers of thermal neutrons chosen for shell or cover are rare-earth elements europium, hafnium, gadolinium, or their alloys with structural materials. EFFECT: improved performance characteristics and safety of nuclear power plant. 2 dwg
