Refurbishment works of the JMTR was carried out in plans from FY2007 to FY2010 and finished all refurbishment work on schedule in this year. Regarding the management and operation of the JMTR, the periodical inspection of facilities based on the law, maintenance and partial renewal works of facilities were carried out, and the fabrication of the fuel for restart has been carried out. As for the management and operation of irradiation facilities, maintenance and partial renewal works of facilities were also carried out. In the hot laboratory, voluntary periodical inspection, maintenance and post-irradiation examinations of irradiated materials were carried out. As for the radiation control at the JMTR facility, irradiation facility and hot laboratory facility, the limit of the radiation exposure dose defined by the safety regulation works were carried out safely under far below. This report describes the FY2010 activities on above mentions.

During the FY2006 (April 2006 to March 2007), the Japan Materials Testing Reactor (JMTR) was operated for three operation cycles from 162nd cycle to 165th cycle. Various irradiation tests and post-irradiation examinations (PIEs) were performed for studies on Irradiation Assisted Stress Corrosion Cracking (IASCC) of light-water-reactor internals, development of the fusion blanket, basic materials researches, radioisotope production, and so on. The operation was stopped by 165th cycle according to schedule. And maintenance work and preservation work of the facilities has been started for the refurbishment of the JMTR. Renewal of equipments and aging management of equipments and reactor facilities were carried out according to long-term maintenance plan which was based on periodical evaluation related to maintenance and safety management of reactor facilities.
