核压力容器 meaning in English

nuclear pressure vessel

Finite element analysis on cylindrical pressure vessel with hillside nozzles
承压热冲击对核压力容器强度的影响
The program fearpv is applied to 3 - d transient sealing analysis of nuclear pressure vessel during the total process , including bolt pretensioning process , heating and compression process , thermostated heating and constant pressure process , and the cooling and decompressing process . according to the analysis and computational results in this thesis , although the actual structure and work conditions of the pressure vessel in nuclear power station are much more complex than that of the pressure vessel model , the program fearpv still can get quite good convergence on the plasticity and
由本文分析计算可知，虽然电站核压力容器的结构及计算工况较压力容器模拟体复杂得多，然而反应堆压力容器瞬态密封有限元分析程序对塑性迭代和接触迭代仍具有很好的收敛性，数值稳定性好，得到的结果具有良好的规律性，在升温、升压、恒温、恒压、降温和降压等过程中其规律和压力容器模拟体基本相似。
