Abstract: The turbine of SCWR is supercritical and impulse which rotors are made of materials maturely used in the turbines of supercritical thermal power plants.The turbine’s seal steam is from clean steam source.In order to realize the sliding pressure startup,the thermal system includes a startup and shut down system which supply sufficient flow for the reactor in startup and shut down phase.This paper describes the turbine and thermal system of SCWR.
