After heat removing device for FBR type reactor

Creators

Description

An annular liquid (water) pool is formed radially surrounding a reactor container and a reactor safety container. An annular cavity wall is formed in the liquid pool, and the inside of the cavity wall is formed as a liquid channel. If the temperature of liquid sodium in the reactor container rises by the after heat of the nuclear fuels, the temperature of the reactor safety container also rises to a high temperature, and the amount of heat radiated from the surface is increased. Water in the liquid channel heated by undergoing the radiation heat forms upward streams in the liquid channel by an air lift-effect caused by rising of boiling air bubbles. Namely, the water in the liquid pool rises the liquid channel while boiling to cool the reactor safety container. With such a constitution, after heat can be removed continuously by the spontaneously circulating water. (I.N.)
