| 摘 要： | 核电厂安全级设备在质量鉴定过程中的样机选型代表性直接关系到将样机鉴定结论外推至电厂实际安装设备的合理性。围绕IEEE标准中的安全级电气设备鉴定样机代表性准则和选型方法进行讨论,重点讨论了选型方法的优化和改进,在标准选型方法的基础上提出了一种基于相关系数的样机代表性计算方法,应用该计算方法所得的鉴定样机选型结果具有符合标准要求、代表性可量化且选型结果准确等特点。

Correlation Coefficient Method to Calculate the Nuclear Safety Equipment Qualification Sample Representativeness |
| |
| Abstract: | The representativeness of nuclear safety equipment qualification sample is directly related to that whether the qualification conclusion can be extrapolated to the actual equipment. The qualification sample repr-esentativeness criteria in IEEE standard and the sample selection method are discussed. A sample representa-tiveness calculation method based on correlation coefficient is proposed. The sample representativeness obtained by the method can be quantified and the results are accurate. |
