Hitachi-GE Nuclear Energy Ltd. (Hitachi-GE) has developed a conceptual design for the Double MS: modular simplified & medium small reactor (DMS) under the sponsorship of The Japan Atomic Power Company. The DMS is one of the small-to-medium sized reactors (SMRs) of boiling water reactor (BWR) type, which has been predicted to overcome almost all economy of scale concerns when compared to proven conventional advanced BWR (ABWR) technologies. The DMS design was dedicated to generate electric power, and in order to enhance flexibility for usage of the DMS, the University of Saskatchewan, Hitachi-GE and Hitachi Ltd. (Hitachi) have collaborated on a joint research and development (R&D) initiative to study the utilization of heat and steam from the balance of plant (BOP) for thermal utilization (TU) applications such as district heating, process heating, etc. Based on the DMS of the 300MWe class, Hitachi is developing heat balance evaluation tools for the BOP system and the intermediate heat exchanger (IHX) system which is implemented for heat transfer from the BOP to the TU application in order to detect radioactive materials from the BOP and to prevent leakage to the TU applications. In this paper, a part of the IHX system heat balance simulator for the co-generation DMS is described.
