Title: Nuclear reactor
Inventor: FUJII TAKAO
IPC: G21D3/08
Filed: 1989-03-22
Abstract: PURPOSE:To contrive prevention of a vibration of the structure in a reacter caused by liquid flowing by arranging shroud support legs in front of a discharging outlet of a coolant circulation pump. CONSTITUTION:A coolant circulation pump part 10 is constituted by placing a cylindrical shroud 6 covering the structure in a reacter 20 at a bottom part of a nuclear reactor pressure vessel 1 and by arranging a plurality of internal pumps at its outer circumference. Shroud support legs 12 are arranged in front of a coolant discharging outlet of the pump part 10 to fix a shroud 6 to the vessel 1 and to form openings 13 between neighboring legs 12. In this way, a coolant flow discharged from the pump part 10 flows into a reactor core from the opening 13 and thereafter each coolant flow collides one another at an intermediate zone of neighboring two pump parts 10 and thus almost no disturbance appears. Therefore, a component of a pressure deviation contained in a flow at the intermediate zone is much decreased and also another pressure deviation working on the structure in the reacter 20 is again much decreased.
