Abstract

1286264 Barium impregnated graphite NUCLEAR POWER GROUP Ltd 1 Aug 1969 [13 Sept 1968] 43579/68 Heading C1A [Also in Division G6] Graphite components in the cooler regions of the core of a nuclear reactor incorporate a catalyst which will increase the rate of reaction between the graphite and the water vapour present in the reactor coolant. Water vapour is removed from the coolant so as to reduce the risk of corrosion in the high temperature regions. For example in a high temperature heliumcooled reactor, some of the moderator blocks or fuel containers are coated or impregnated with barium catalyst, for example by treatment with a solution of a barium salt or oxide or by means of a barium vapour process.
