The feasibility study of a distributed small reactor system has been performed in JAERI for the utilization of the heat source for public welfare, especially for air-conditioning and hot water supply, from the view point of use expansion of nuclear energy. In this report, the optimization of heat supply system including the set up and analysis of the model city are studied for the prediction of short and long term heat demand in the heat supply area. It is important process for understanding the whole system image to estimate the suitable heat source scale for the heat demand of the heat supply area, which is within a 5-km radius from heat supply source. From the analysis, it is clear that two or more set of the nuclear reactors based on 100 MW thermal power are suitable. Furthermore, it is indicated that the introduced reactor system can be utilized for more than 30 year and the heat reserve system is indispensable. This results show the feasibility of a small reactor system for district heat-and cooling supply.
