REVIEW OF DESIGN STUDIES FOR HIGH PERFORMANCE LIGHT WATER REACTORS
Light water reactors operating under supercritical pressure conditions have been selected as one of the promising future reactor concepts to be studied by the Generation Ⅳ International Forum. Having a single phase coolant, a boiling crisis in the core can be avoided. The high core outlet enthalpy will increase efficiency and the specific power of the steam cycle. Moreover, the once through steam cycle reduces the plant complexity and thus costs. A first option considered in this context is a pressurized water reactor with 380℃ core exit temperature, having a closed primary loop and achieving 2％ pts. higher net efficiency and 24％ higher net specific turbine power. Core and assembly designs have been worked out and a reactor pressure vessel has been designed accordingly. A higher advantage can be gained from core exit temperatures around 500℃ which require a multi step heat up process in the core with intermediate coolant mixing, and which achieve 44％ net efficiency or more. The paper will provide a review of recent design approaches for such High Performance Light Water Reactors.
