The new research reactor (abbreviated as "New Research Reactor"), which is planned to be installed at the Monju site, is a medium-power reactor whose main purpose is to utilize neutron beams, and its thermal power is less than 10MW. In order to achieve maximum performance under these conditions, the New Research Reactor needs to be designed taking into consideration various factors from various perspectives, such as a compact core design and a high-performance cold neutron source (CNS). In addition, to maximize the number of neutron beam instruments and irradiation devices to be installed in this New Research Reactor and to maximize their performance, various factors including requests from the users of those instruments/devices are being considered and a layout plan is being prepared in the reactor room. In the presentation, the current proposal for the layout of the utilization facilities and equipment for the New Research Reactor will be reported.
