原子力機構は、JMTRを原子力の基盤技術を支える原子炉と位置づけ、2011年度から再稼働することを目指し、2007年度から改修に着手することを決定した。そこで、2007年度から4年間で原子炉機器の更新を実施し、2011年度から再稼動させるために原子炉機器の更新計画を策定し、現在、改修工事を実施している。本報では、継続使用する機器の選定基準及びその概要についてまとめるとともに、更新工事の工程の基本的な考え方についてまとめた。

Operation of the Japan Materials Testing Reactor (JMTR), a light-water-cooling tank-type reactor with a 50 MW thermal power, was stopped in August 2006, and now its refurbishment is on going. The reactor facilities are to be refurbished during four years from the beginning of FY 2007, and the renewed JMTR will be operated from FY 2011 until around FY 2030. As for the decision of the refurbishment, reactor facilities to be renewed and to be continuously used were selected from a viewpoint of ensuring safety, improvement of availability-factor, etc. The selected renewal reactor facilities were the reactor instrument and control system, cooling system, radioactive waste facility, power supply system, boiler, etc. Presented are the basic idea on selection of the renewal facilities, outline of these facilities and schedule of refurbishment work.
