Abstract

1309883 Nuclear reactors UNITED KING- DOM ATOMIC ENERGY AUTHORITY 3 March 1972 [18 March 1971] 7255/71 Heading G6C In a nuclear reactor construction, heat is transferred from the nuclear fuel to heat energy conversion apparatus by use of a finely-divided solid material as a heat transfer medium. In one form, the heat-transfer medium, which also acts as moderator falls from the reactor vessel on to a heat exchanger under the influence of gravity; the flow may be regulated by a valve. In another form, in which the heat exchanger is remote from the vessel, the heattransfer medium is conveyed to above the heat exchanger by conveyer. The heat-transfer medium is returned to above the fuel by conveyer. The heat-transfer medium may be finely-divided graphite, and may be maintained in a free flowing condition by vibrating or pulsating means. Reactivity in the core can be varied by raising and lowering the fuel elements. Emergency shut-down is effected by injecting neutronabsorbing material into containers penetrating the graphite mass. The fuel elements may be sheathed, or may comprise fission-product retaining particles in a matrix which has no sheath. An inert covered gas may be used in the system. Where the construction is to be used for generating electricity, power cylcing of the reactor is reduced by storing hot cooling and moderating material during periods of low heat energy consumption.
