Design and safety concepts of an integral reactor for nuclear cogeneration power plant

An integral reactor concept of 330 MW thermal power for nuclear cogeneration plant is under development at Korea Atomic Energy Research Institute (KAERI). The reactor will be utilized as an energy source for seawater desalination as well as for small scale power generation. Advanced technologies such as intrinsic and passive safety features are implemented in establishing the design concepts to enhance the safety and performance. Research and development including laboratory-scale tests are concurrently underway to evaluate the characteristics of various passive safety concepts and provide the proper technical data for the conceptual design. This parer describes the preliminary safety and design concepts of the integral reactor for nuclear cogeneration plant. Salient features of the design are extended fuel cycle, once-through helical steam generator, self-pressurizer, and seismic resistant fine control CEDMs, passive residual heat removal system, and steam injector driven passive containment cooling system
