摘要
最佳估算加不确定性方法能够消除常用方法所导致的过度保守性。基于RELAP5程序的最佳估算加不确定性分析方法,在充分吸收不确定性分析方法经验基础之上,考虑了初始条件、边界条件以及模型不确定性,以统计方法得到满足概率要求的结果。并将该方法应用于再淹没试验NEPTUN数据的分析,证明各不确定性参数的选取及评价的正确性。
Best estimate plus uncertainty method could be used to eliminate the over-conservatism in the current method and gain more safety margin. In the current paper, uncertainty method which has considered the effect of the initial conditions, boundary conditions, and model uncertainties has been developed based on the best estimate code RELAP5. This method was used to analyze the NEPTUN reflood experiment. The results showed that the new method was reasonable.
