A simulator for materials testing reactors was developed in order to utilize for a nuclear human resource development and to promote the partnership with developing countries which have a plan to introduce nuclear power plant and/or experimental research reactor. The simulator is designed based on JMTR, and simulates normal, transient and accident conditions, and also irradiation tests such as material testing under BWR condition. The simulator is composed of a computer system, control panels with large-size displays for reactor control, process control, irradiation facility control and an instruction. In the simulation, the reactor is operated with cooling system for 30 days a cycle at 50 MWth same as the JMTR. Outputs, such as neutron flux, temperature and flow rate in the core are shown in real time in collaboration with Excel.
