- 出版タイプ: NA高温工学試験研究炉(HTTR)の原子炉施設の非常用電源設備として、ガスタービンエンジンの非常用発電機が設置されている。非常用発電機の性能の維持管理を目的に、分解点検や保守管理を設備設置時から現在に至るまで実施し、改良,改善を行ってきた。主な改善として、今まで行ってきたガスタービンエンジンの起動時間の監視に、起動時における排気最高温度を追加監視することにより、その劣化の程度を十分に推測できること及び急激な劣化の発生を判断できるようになった。The emergency power feeders of the High Temperature Engineering Test Reactor (HTTR) have gas turbine generators which are composed of gas turbin engines, generators and current breakers. The gas turbine generators have been overhauled and maintained to keep the performance. The maintenance technology was upgraded by improving their parts and surveillance method on the basis of the operational and maintenance experience. It can be clarified that the deterioration levels and the sudden deterioration timing are judged at an early stage by measuring the max exhaust temperature at the time of start in addition to check the starting time of the Gas Turbine Engines.
