NUCLEAR PLANT WITH A PEBBLE BED NUCLEAR REACTOR

摘要

This invention relates to a nuclear plant 10 including a main power system(12) and a fuel handling and storage system (14). The system (14) is connectedto a sphere inlet (22) and a sphere outlet (24) of a multi-pass hightemperature gas cooled pebble bed reactor (16). The system (14) is configuredsuch that gas flows from the system (14) into the reactor (16) through boththe sphere inlet (22) and the sphere outlet (24) thereby inhibiting theingress of high temperature gas from the reactor into the system (14).Restricting indexers (66, 68) permit the movement of spheres between thereactor (16) and the system (14) and dampen out the transmission of pressurefluctuations from the power system (12) to the system (14).
