Abstract
It is desirable to being able to vary the temperature of a loop exposed to a flow of hot gases in gas cooled nuclear reactor installations without thereby affecting the gas temperature in the other loops. It should be possible in an extreme case to take the affected loop out of service. This is achieved by arranging under the heat absorbing components in the hot gas channel a means for mixing gas connected with a cold gas line.
Claims12
A gas cooled nuclear reactor comprising:
- a reactor core, at least one closed circuit having a heat absorbing member for receiving cooling gas from said reactor core, a hot gas conduit and a cold gas conduit connecting said heat absorbing member to said reactor core and means for mixing at least a portion of a cooled cooling gas from an outlet side of said heat absorbing member with hot gas downstream of said reactor core and in said hot gas conduit, said means comprising at least one adjustable valve, a conduit connecting said valve with said cold gas conduit and a plurality of tubes projecting into said hot gas conduit, and a distributor head having a plurality of orifices mounted on each of said tubes for dispersing cold gas into said hot gas conduit thereby controlling the temperature of said cooling gas.
The gas cooled nuclear reactor of claim 14 wherein said heat absorbing member comprises a heat exchanger.
A process for controlling the temperature in a circuit of a high temperature gas cooled nuclear reactor comprising:
- flowing hot gas from a reactor core through a hot gas conduit and then into a heat absorbing member where it is cooled, and then flowing cooled gas through a cold gas conduit and back to a reactor core;
- diverting at least a portion of said cooled gas flowing through said cold gas conduit to a gas mixing device;
- introducing said diverted cooled gas from said gas mixing device into said hot gas from said reactor through a plurality of tubes extending into said hot gas conduit before entry of the hot gas into said heat absorbing member, said cooled gas being introduced through a plurality of multiple orifice distributor heads respectively mounted on said plurality of tubes, said portion of cooled gas being controlled by an adjustable valve member.
