A High Temperature Wide Range Neutron Monitoring System (HWNMS) was developed for High Temperature Gas-cooled Reactors (HTGRs) by Japan Atomic Energy Research Institute (JAERI). The special features of the HWNMS are as follows. The neutron sensor can be installed inside the pressure vessel of the HTGR. The maximum operating temperature of the neutron sensor is 800°C. The HWNMS is designed to have low electric noises. The HWNMS provides the neutron flux monitoring and a reactor period indication from sourcerange to power range. The HWNMS is designed to satisfy the requirements for the Post-Accident Monitor (PAM) of the HTGR. The performance test of the HWNMS was carried out in the research reactor, JRR-4, in Japan. The demonstration test was also performedin the actual high temperature gas-cooled reactor, AVR, in the Federal Republic of Germany. |
