台山核电厂1、2号机组设计可利用因子核算

Verification of Taishan NPP units 1&2 design availability factor

台山核电厂1、2号机组NIEP合同附件5L2.1要求:燃料循环长度大于等于18个月时,20年运行时间内的年平均设计可利用因子为92%。本文分析了EUR第2卷第18章中的性能评价方法,修正其计算公式中的错误,并通过核算台山核电厂1、2号机组设计可利用因子验证修正后的计算公式的正确性。本文可供设计新核电厂时确定和评价设计可利用率性能指标参考。

Appendix 5L 2.1 nuclear island engineering N- supply contract （NIEP） of Taishan NPP Units 1＆2 requires： the average design availability factor is 92%, for a fuel cycle≥8 months, over a 20 year-period. The performance assessment methodology in EUR Volume 2, Chapter 18 is analyzed and the error in the EUR formula is modified, which is validated by verifying Taishan NPP Units 1＆2 design availability factor. It can be used as a reference for determining and evaluating the design availability factor performance indicator for a new nuclear power plant design.
