Abstract

1390907 Controlling nuclear reactors BRITISH NUCLEAR DESIGN & CONSTRUCTION Ltd 23 March 1972 [23 Dec 1970] 61106/70 Heading G6C A fluid-cooled reactor (e.g. helium-cooled HRT). with a core negative temperature coefficient of reactivity is controlled, to produce a rapid reduction in core thermal output, by reducing the coolant mass flow rate whereby the temperature rises and reactivity falls. The flow rate reduction may be effected by shutting down main boilers and coolant circulators while leaving auxiliary boilers and circulators operative. Simultaneously with the flow rate reduction, some of a group of control rods are introduced into the core to reduce its thermal output by an amount less than would accord with the reduced flow rate. The temperature rise is thus such as not to initiate a full reactor shut-down by tripping energency shut-down systems. The procedure is invoked when a short-term fault in the main turbogenerator or grid results in a decrease in demand on the reactor. The arrangement of main and auxiliary boilers is as disclosed in Specification 1,368,954.
