JMTR (Japan Materials Testing Reactor) has started refurbishment of reactor facilities from FY2007, and the renewed and upgraded JMTR will start from FY2011. Control system of the JMTR has been used for 42 years since first criticality in 1968. Distributed control system (DCS) introduced in this project will enable the operators to monitor and control the entire plant information on a unified platform and realize digitalization / integration of various data. In addition, adoption of large screens will make it possible to show versatile information collectively, and it will lead to increase operability, visibility and assistance for plant operators. For the reactor control room, new layout design is introduced based on desired ergonomics. This report summarizes the outline of refurbishment project on plant control upgrading from analog control panels to the latest distributed control system (DCS).
