METHOD FOR RETROFITTING URANIUM-GRAPHITE REACTOR CORE Russian patent published in 2000 - IPC

Abstract RU 2147147 C1

FIELD: nuclear reactors. SUBSTANCE: pressurized vertical channel is made in top metal structure of uranium-graphite reactor, in vicinity of gas-steam mixture header, between process channels and cooling channels of deflector for sequential removal of upper metal and graphite blocks; then graphite and metal blocks shaped at one of side fins are dropped in reverse sequence into emptied space and form channel for jacket used to mount material radiation processing devices at the same time ensuring contact between graphite blocks and external surface of jacket. EFFECT: improved productivity of radiation technologies, increased diameter of parts subjected to irradiation. 7 dwg
