IMPROVEMENTS IN OR RELATING TO PLANTS INCLUDING NUCLEAR REACTORS

Patent ·
OSTI ID:4010475
The described process relates to plants containing a gas cooled reactor in which the coolant, after being heated in the reactor, is arranged to heat a vapor generator and sub sequently an economizer before being recirculated. One valve with four outlets is used so that control is more satisfactory. Such a valve called for rearrangement of the piping system. Fluid from the separator drum is circulated at a variable rate through the economizer to adjust the temperature of the coolant entering the reactor. This allows the coolant temperature to be adjusted for the falling reactor load, avoiding shut-down in many cases. By elevating the coolant inlet temperature, the life of the uranium metal fuel elements is prolonged. (N.W.R.)
