Development of Integrated Modular Water Reactor

Abstract

The primary strategy in the development of small-scale reactors is to construct a new design concept which satisfies the requirements of enhanced safety, capital cost reduction and proliferation resistance. For this goal, a reactor vessel with an integrated primary system configuration is chosen as the most optimum reactor configuration in the present work. This configuration adopts natural circulation and self-pressurization systems, which eliminate pressurizer, reactor coolant pumps and all loop pipings. In addition to these basic designs, the innovative technologies of Hybrid Heat Transport System (HHTS) and Stand-alone Direct Heat Removal System (SDHS) have been developed to improve economy and safety. This plant is named as Integrated Modular water Reactor (IMR).
