该压力容器为反应堆主容器,安全级别为安全1级(SC-1)。容器的工作介质为去离子水,所选用的主体材料为SA-508Gr.3Cl.1钢锻件。容器设计标准为ASME第Ⅲ卷NB分卷,采用分析设计方法进行设计,其设计温度为300℃,设计压力为17.2 MPa,快中子辐照累计剂量小于1×10~(20)cm~(-2)。容器的设计、分析和计算必须考虑正常运行、预计运行事件,以及事故工况下的机械载荷、热载荷、腐蚀、浸蚀及辐照等作用,并进行评价。另外,设
The pressure vessel is the main reactor vessel and has a safety class of safety class 1 (SC-1). The working medium of the container is deionized water, and the selected main material is SA-508Gr.3Cl.1 steel forgings. The design standard of container is ASME Volume III NB sub-roll, which is designed by analytical design method. The designed temperature is 300 ℃, the design pressure is 17.2 MPa, the cumulative dose of fast neutron irradiation is less than 1 × 10 ~ (20) cm ~ ( -2). The design, analysis and calculation of the vessel must be considered and evaluated for normal operation, anticipated operational occurrences, mechanical loads, thermal loads, corrosion, erosion and exposure under accident conditions. In addition, suppose
