Abstract
1,158,885. Cooling reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. 30 Dec., 1966 [30 Dec., 1965], No. 58425/66. Heading G6C. A method for eliminating the impurities formed by radiolysis in CO 2 gas, used as coolant in a graphite-moderated nuclear reactor and to which a small proportion of methane has been added to inhibit the reaction between the CO 2 gas and the graphite, comprises the conversion of H 2 O into H 2 by the action of CO on H 2 O, and the conversion of H 2 into CH 4 by the action of CO or CO 2 gas on H 2 . The first conversion may be effected by passing a portion of the reactor coolant through a catalyst having a basis of Cu and Zn at a temperature between 170‹ and 200‹ C., and the second conversion using a catalyst having a basis of Ni, Co or Ru at a temperature of 250‹ C. The two conversions may be repeated alternately several times in different catalytic reactors. Alternatively, a single catalytic reactor may be used in which catalysts for both conversions are either mixed or disposed in alternate beds, or a single catalyst for both conversions may be used. The methane content of the coolant is controlled by the introduction or withdrawal of either water or hydrogen.
