Abstract

1,271,347. Controlling reactors. SIEMENS A.G. 3 Sept., 1970 [5 Sept., 1969], No. 42320/70. Heading G6C. The power output of a reactor is controlled by common drive means coupled to a bank of control rods to move them axially so as to change their degree of insertion in the reactor core, but rapid reduction of the power output is achieved, when required, by causing a control rod of the bank to be moved axially, at a rate which is high in comparison with that at which the common drive means move the control rods of the bank, from a withdrawn position of the bank to a fully-inserted position, whilst other control rods of the bank remain in the withdrawn position. The reduction in power output may be required because of a failure of a main coolant pump, or because of load shedding or sudden reductions in load. More than one of the control rods of a bank may be rapidly inserted, and this insertion may take place by automatic actions or manually. A control rod which has been rapidly inserted is withdrawn, shortly after having been inserted, at a selectively variable speed, and the common drive means are used to move the other control rods of the bank to bring the power output of the reactor to a desired level.
