FISSION IONIZATION CHAMBER Russian patent published in 1997 - IPC

FIELD: nuclear energy technology. SUBSTANCE: compensation section electrode of fission ionization chamber has radiator made by uranium containing material and filter connected electrically with electrode at both sides of it. Compensation section radiator uranium content is (1+E) times more with respect to working section radiator content factor where E is relative absorption factor of fission products electron radiation while filter crossing through. Filter thickness is equal to splinters free path greatest value for filter material which is choosing electrically conductive with low activation cross-section. EFFECT: more effective monitoring of nuclear reactor operation. 1 dwg
