WATER-COOLED NUCLEAR REACTOR Russian patent published in 1995 - IPC

Abstract RU 2032946 C1

FIELD: nuclear technology. SUBSTANCE: water- cooled nuclear reactor has active zone with spherical nuclear fuel with protective coat and light-water moderator-heat transfer agent surrounder with reflector and placed into pressure vessel. Enrichment of nuclear fuel in each elementary cell of active zone amounts to 5-25% and its volumetric share is from 0.015 to 0.76. Volumetric share of water in cell amounts to 0.1-0.25. Remaining volume is filled with expelling agent produced from material having smaller microsection of absorption of thermal neutrons than that of light-water moderator. EFFECT: enhanced operational efficiency. 9 cl, 9 dwg, 3 tbl
