Nuclear reactor safety system - Wikipedia

Reactor protection system (RPS) A reactor protection system is designed to immediately terminate the nuclear reaction. By breaking the nuclear chain reaction, the source of heat is eliminated.Other systems can then be used to remove decay heat from the core. All nuclear plants have some form of reactor protection system.

The residence time in the reactor is controlled by the feed rate of reactants to the reactor. For example, if a reactor has a volume of 20 m 3 and the feed rate of reactants is 40 m 3 h-1 the residence time is 20 m 3 /40 m 3 h-1 = 0.5 h. It is simple to control accurately the flow rate of reactants.

In some cases a Fuzzy Logic Controller (FLC) can give control superior to PID. When there's no jacket but only electrical heating of the reactor, the FLC can provide the fastest possible heating of the reactor with no overshoot or oscillation. Again, the modern control system makes it easy to install this controller. Achieve better control
