• 一般注記: A long-life in-core neutron detector was developed from 1973 through 1978 and since then, it has been applied to the prototype heavy water reactor "Fugen" as a local power monitor. More than 10 year's operation experience of the detector proved its performance as was expected. The detector is a fission chamber of regenerative type whose tube is made of zircaloy-2 metal for neutron economy. In-core neutron detectors for the local power monitor are placed in heavy water moderator of 50 c. The in-core conditions bring a high level thermal neutron flux environment. It tends to hurt the lineality and shorten the life time of the detectors because of rapid burnup of the neutron conversion material($^{235}$U)in thedetector compared to the light water reactors.These problems were solved by some improvements and it was demonstrated that the detector had the performance of high linearity and long-life characteristics.; None
