Light-water breeder reactor
Abstract
Abstract A LIGHT-WATER-MODERATED AND -COOLED NUCLEAR BREEDER REACTOR OF THE SEED-BLANKET TYPE CHARACTERIZED BY CORE MODULES COMPRISING LOOSELY PACKED BLANKET ZONES ENRICHED WITH FISSILE FUEL AND AXIAL ZONING IN THE SEED AND BLANKET REGIONS WITHIN EACH CORE MODULE. REACTIVITY CONTROL OVER LIFETIME IS ACHIEVED BY AXIAL DISPLACEMENT OF MOVABLE SEED ZONES WITHOUT THE USE OF POSION RODS IN THE EMBODIMENT ILLUSTRATED. THE SEED IS FURTHER CHARACTERIZED BY A HYDROGEN-TO-URANIUM-233 ATOM RATIO IN THE RANGE 10 TO 200 AND A URANIUM-233-TO-THOIUM-232 ATOM RATIO RANGING FROM 0.012 TO 0.200. THE SEED OCCUPIES FROM 10 TO 35 PERCENT OF THE CORE VOLUME IN THE FORM OF ONE OR MORE INDIVIDUAL ISLANDS OR ANNULI.
