COMPACT PRESSURIZED WATER NUCLEAR REACTOR

摘要

A compact PWR, comprising a vessel (10) containing a reactor core (14) and closed by a cover with a steam generator (12), incorporating a primary circulating pump (28) and a pressurizer (30), has the pump and pressurizer contained within the reactor vessel to form a fully integrated primary circuit. Control bar (40) operating mechanisms are also located within the vessel, which has an inner annular partition (15) which contains the reactor core and pressurizer at the bottom and top respectively, with the pump round the outside of its upper section.
