CORE OF THE CHANNAL NUCLEAR REACTOR AND FUEL ASSEMBLY OF THE WATER-COOLED NUCLEAR REACTOR

摘要

FIELD: nuclear power engineering. SUBSTANCE: fuel filling the fuel assembly has in its composition uranium dioxide and erbium oxide dope whose content is not to exceed 0.46 mass percent of erbium; mass proportion of U-235 equivalent in fissionable fuel is to be 2,35 to 2.65 mass percent so as to ensure uniform spatial energy distribution of neutrons while retaining adequate fuel properties. EFFECT: improved fuel burn-up and uniformity of spatial energy distribution of neutrons. 2 cl
