Reactor control device

Purpose: To effectively and readily control a nuclear reactor and facilitate the effective shortening of a fuel control operation and the load follow-up operation. Constitution: Data such as critical power rise ratio, limited value, characteristics and operating sequence and so forth are input beforehand into a process computer, reactor operating conditions are input through an operating condition input mechanism to the computer, the power distribution or the like in the case where the operating conditions are executed in the reactor is estimated and calculated on the basis of the above data and the process signals from the reactor, and the results are indicated. Accordingly, the operator for the reactor can readily, simply and effectively obtain an estimation of the power distribution or the like merely by inputting the operating conditions of the reactor into the input mechanism.
