SELF-POWERED EXCORE DETECTOR ARRANGEMENT FOR MEASURING FLUX OF A NUCLEAR REACTOR CORE

摘要

An excore detector assembly for measuring flux outside of a nuclear reactor core. The excore detector assembly includes a housing and at least one self-powered detector inside the housing for measuring flux generated by the nuclear reactor core. The at least one self-powered detector includes a sheath, a detector material section inside the sheath, an insulator between the sheath and the detector material, and a flux signal output line.
