A FORCED COOLING CIRCULAR DEEP-WATER POND TYPE HEAT SUPPLY NUCLEAR REACTOR WITH NATURAL CIRCULATION

摘要

A forced cooling circular deep−water pond type heat supply nuclear reactor with natural circulation comprises a water pond, a reactor core, a control stick, and a heat exchanger. The reactor core is placed in the ground of the water pond, the control stick is placed inside of the reactor core, the heat exchanger's outlet is connecting with water in the pond by circular pump, and its inlet is connected with the reactor core, wherein said heat exchanger and the circular pump locate outside of the water pond, and the depth of pond's water is 10−60 meters. The circular pump is a vane circular pump with high revolution ratio. The nuclear reactor according to present invention adopts forced circular method with natural circulation. When forced circulation translates into natural circulation, it can realize non−energy driven conversation, while the parameters such as temperature of the reactor water cannot rise abruptly and can change continuously. While it is changed, it can directly result in descend of reactor power and halt without other halting measure.
