摘　　要：验证与确认是软件生命周期中的重要环节,反映软件研发真正走向实际应用的过程,是软件从“书架”走向“货架”的重要标志。基于核电厂包括CNP300、M310、CNP650、BEAVRS和HPR1000在内的5种型号商用压水堆共计48个运行循环的实际测量数据,对NECP-Bamboo软件进行了验证与确认。结果表明,采用NECP-Bamboo软件计算获得的控制棒价值、温度系数、临界硼浓度和组件功率分布等堆型关键参数的计算值与实测值误差均能满足工业限值的要求。各个型号堆型相应关键参数误差的95%置信区间范围汇总如下:临界硼浓度为[-37.80,35.39]ppm,控制棒的价值为[-6.18%,3.68%],温度反应系数为[-3.27,2.99]pcm/K,组件相对功率在大于和小于0.9时分别为[-0.64%,-0.12%]和[1.18%,2.94%]。The verification and validation(V&V)are important aspects in the life cycle of engineering software,and reflect the process of software development to practical application.They are also significant symbols of software from"bookshelf"to"goods shelf".In this paper,V&V for the software NECP-Bamboo were carried out based on the actual measurement data of five types of commercial pressurized water reactors,including CNP300,M310,CNP650,BEAVRS and HPR1000,for a total of 48 operation cycles.The results show that the errors between the calculated values and the measured values of the key reactor parameters,such as control rod worth,temperature coefficient,critical boron concentration and assembly power distribution,obtained by using NECP-Bamboo can meet the requirements of industrial limits.The 95% confidence interval range of the corresponding key parameter errors of various types of reactors is summarized as follows:[-37.80,35.39]ppm for critical boron concentration,[-6.18%,3.68%]for control rod worth,[-3.27,2.99]pcm/K for the reactivity coefficient of temperature,[-0.64%,-0.12%]for the assembly power distribution when the relative power is greater than 0.9,and[1.18%,2.94%]for that when the relative power is less than 0.9.
