Abstract

968,889. Reactors. UNITED KINGDOM. ATOMIC ENERGY AUTHORITY.. June 25,1962 [June 28, 1961]. No. 23410/61.Heading. G6C. The reactivity of a nuclear reactor is controlled by adjustment of the level of the light water moderator in which the cam is immersed. As shown, the moderator 3 surround the core 1 and the inverted vessel 4 is mounted in 3, beneath 1. Air may be pumped into 4 through the valve 8 and pipe 5, thereby lowering surface B and raising - surface A. The level of the surface at B is indicated by the flowmeter 11 operated by a flow of air through the holes 10a in conduit 10. The reactivity of the reactor is rapidly -reduced by opening valves 6. The impact of the rapidly rising level B in the upper surface of 4 is reduced by the trapping of volume of air determined by the extension 12.
