| 内容記述 | tThe ITER blanket remote handling system (BRHS) will be operated in a high radiation environment(250 Gy/h max.) and must stably handle the blanket modules, which weigh 4.5 t and are more than1.5 m in length, with a high degree of position and posture accuracy. The reliability of the system canbe improved by reviewing the failure events of the system caused by high radiation. A failure mode andeffects analysis (FMEA) identified failure modes and determined that lubricants, O-rings, and electricinsulation cables were the dominant components affecting radiation hardness. Accordingly, we tried tooptimize the lubricants and cables of the AC servo motors by using polyphenyl ether (PPE)-based greaseand polyether ether ketone (PEEK), respectively. Materials containing radiation protective agents werealso selected for the cable sheaths and O-rings to improve radiation hardness. Gamma ray irradiation tests were performed on these components and as a result, a radiation hardness of 8 MGy was achievedfor the AC servo motors. On the other hand, to develop the radiation hardness and BRHS compatibility furthermore, the improvement of materials of cable and O ring were performed. | |||||
