CALIFORNIUM-252 BASE NEUTRON SOURCE FOR MONITORING NUCLEAR REACTOR OPERATION Russian patent published in 2004 - IPC

Abstract RU 2235377 C2

FIELD: nuclear engineering.

SUBSTANCE: proposed californium-252 base neutron source designed for controlling operation of nuclear reactor has capsules and core produced by immobilizing californium-252 in porous blank made of platinum or aluminum oxide. Capsules are made of steel resistant to corrosion by liquid sodium and capable of retaining its geometry and strength characteristics at detrimental radiation dose in nuclear reactor exceeding 30 shifts per atom.

EFFECT: enhanced reliability of neutron source capsules.
