摘　　要：应用根据Wilks公式发展的抽样统计方法及VIPRE-W程序计算DNBR和出口含汽率的参数不确定性,再结合模型与DNB关系式不确定性,得到DNBR的设计限值为1.220。与RTDP方法得到的DNBR限值进行比较,得出此方法能得到更多的DNBR裕度。The parametric uncertainties of DNBR and exit quality were calculated using sampling statistical method based on Wilks formula and VIPRE-W code.Then the DNBR design limit and exit quality limit were got by combining with the uncertainties of models and DNB correlation.This method can gain the more DNBR margin than RTDP methodology which is developed by Westinghouse by comparison of these two methods.
