Development of fission ionization chamber detector for reactor neutron flux measurement
摘要
Abstract
In order to establish a monitoring device for reactor neutron flux measurement to meet the measurement requirements of ex-core nuclear measurement system,a fission ionization chamber detector with long sensitive region,wide range,high sensitivity and strong γ-suppression ability has been developed.At the same time,the thermal neutron sensitivity,high voltage plateau characteristic,screening threshold plateau characteristic and γ sensitivity of the fission ionization chamber detector are tested and verified.The test results show that the comprehensive performance of the fission ionization chamber can meet the application requirements of the intermediate range measurement channel for ex-core nuclear measurement system of the AP1000 series nuclear power plant.关键词
