| Objective To conduct pressure vessel design and analysis based on the heating-reactor, named Heating-reactor of Advanced low-Pressurized and Passive Safety system (HAPPY). Methods The design followed the design philosophy of inte-grating developed technologies, passive safety and high economic efficiency. According to the characteristics of HAPPY200, the pressure vessel design was conducted based on the requirements on reactor physics, thermal hydraulics and etc. The pressure vessel design was evaluated by the ASME Boiler and Pressure Vessel Code (ASME B&PVC). It was a 200MWth two-loop low-pressurized water reactor with low thermal parameters. The whole reactor vessel was deployed inside a shielding and cooling pool with thermal insulation measure. The design temperature and pressure were 120 ℃ and 1.6 MPa. Stainless steel was adopted for the pressure vessel and the thickness was 35 mm. Results The result obtained from the structure was smaller than the limit required in ASME B&PVC criteria. Conclusion The pressure vessel design of HAPPY200 fills the requirements from reactor physics, thermal hydraulics and etc. The stress analysis of the pressure vessel also meets the ASME B&PVC criteria. |
