Inherent Safety Free-Scale Reactor KAMADO-FSR Estimation of Investment and Cost

We designed a new concept of an inherent safety and free-scale reactor, KAMADO-FSR, which uses a two-phase flow for cooling, similar to BWR (Boiling Water Reactor).The fuel assembly, consisting of a SiC block, is loaded in an atmospheric pressure reactor water pool.As the SiC block fuel assembly becomes a pressure boundary, the present reactor concept requires no pressure vessel.With the high thermal conductivity of SiC, the fuel assembly allows the coolant to become dry-out conditions, eliminating the need for steam drying equipment and improving safety performance.The power scale can be varied from 300 MWe to 1000 MWe without modularization, and the reactor's investment and cost can also be reduced significantly.
