Multiplication factor in nuclear reactor
WebThe effective multiplication factor – k eff is a measure of the change in the fission neutron population from one neutron generation to the subsequent generation. But sometimes, it is convenient to define the change in the keff alone, the change in … WebDetailed knowledge of all possible operational factors that may affect the multiplication factor of the system is of importance in reactor control. It was stated the keff is during reactor operation kept as near to the value of 1.0 as possible. Many factors influence the criticality of the reactor.

If k is exactly 1, the reactor is said to be critical if / < 1, it is subcritical if / > 1, it is supercritical. The neutron population and the reactor power depend on the difference between k and 1, ie, bk = k — K ...
