The flow diagram of RVCS is shown in Fig 2 The system consists of a RPV recuperator(RVR), a RPV cooler(RVC), orifices and valves As illustrated in Fig 1 and Fig 2, a bypass flow is extracted from the blower outlet and flows downward through the tube side of the RVR, which is installed in the annular region outside the IHX, and is cooled down from 550t to 250 Then the cold bypass flow enters an annular channel outside the RVR and flows upward into the shell side of a little cooler (RVC) and is cooled form 250°c to 190 t , the 190 c cold gas enters the gap between the RPV and core vessel and is heated by the two vessel from 190 to 220x At last, the 220 X bypass gas flows upward through some vertical pipes and comes into the RVR shell side and returns to the blower inlet The main technical data of the RVCS is given in table 4...
