WATER-MODERATED POWER REACTOR CORE Russian patent published in 1999 - IPC

Abstract RU 2126999 C1

FIELD: nuclear power engineering; core fuel assemblies. SUBSTANCE: core has fuel assemblies built up of fuel rods; at least one fuel assembly has 270 fuel rods with outer diameter of rod cladding from 5,85•10-3 to 6,17•10-3 m and its inner diameter from 5,01•10-3 to 5,23•10-3 m or 216 fuel rods with outer diameter of rod cladding from 6,66•10-3 to 6,99•10-3 m and its inner diameter from 5,68•10-3 to 5,95•10-3 m. Water-to-uranium ratio for these sizes of fuel rods is chosen between 1.6 and 2.0. EFFECT: enlarged power control range of reactor, improved fuel burn-up, and reduced fuel-rod depressurization probability. 3 cl, 4 dwg
