Abstract

A pressurised water power reactor has two main groups of control rods, an L-group of high control reactivity and partial penetration of the core, and a D-group of lower control reactivity and full core penetration. The rods of the D-group can be interchanged (in their functioning) automatically by a timer, esp. operating in a cycle of 10 mins.-2 hrs. More spec., this timer can be connected to a computer, which determines which rods should be interchanged as a function of the local burn-up. The effectiveness (control reactivity) of the rods is reduced by loxal xenon poisoning in the core. By varying the action of the rods, this local loss of rod effectiveness is reduced, enabling a better, more rapid control of the reactor to be attained.
