Abstract

1,020,668. Cooling reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Jan. 15, 1965 [Feb. 24, 1964], No. 7685/64. Addition to 880,489. Heading G6C. In nuclear reactor coolant flow restrictor of the type described in the parent Specification a bellows filled with an expansible fluid is inserted in a coolant channel and adjusts a throttle in correspondence with the coolant temperature. The bellows is of annular form to permit free flow of coolant through the centre. The restrictor may be used in a sodium cooled fast reactor.
