HEAVY-POWER FAST REACTOR CORE Russian patent published in 1999 - IPC

Abstract RU 2126558 C1

FIELD: nuclear power engineering. SUBSTANCE: hollow core for fast reactors of class 1000 MWe has set of fuel assemblies holding nuclear fuel and arranged in circular manner. Control rods are mounted over circumference concentrically to annular hollow core. The latter is capable of minimizing reactivity of sodium voids and ensuring inherent potential safety even in case of expected transient process without emergency shutdown of reactor. Core hollow may be used for mounting various reactivity self-relaxation mechanisms. EFFECT: improved safety. 6 cl, 20 dwg
