CESIUM ACCUMULATOR Russian patent published in 1996 - IPC

FIELD: nuclear reactor. SUBSTANCE: cesium accumulator has shell with base cover, block of substance-accumulator with through central hole placed between base and bearing disc, rod rigidly anchored on base and passing along axis of central hole, restoring element located between shell cover and bearing disc. Accumulator is provided with cylindrical insert with longitudinal corrugations placed uniaxially to shell along its entire length. Bearing disc has through duct communicating space of central hole with space of shell between bearing disc and cover and plastically deformed element bearing against locating arm of rod. EFFECT: enhanced reliability, improved mass and size characteristics by way of maximal use of absorbing capabilities of substance-accumulator thanks to decrease of compressing loads acting on it under operational condition, increased stability of accumulator to static and vibration overloads in process of guiding of nuclear reactor into orbit. 1 dwg
