EPR机组首堆试验项目选取与实施

为满足国家核安全局（NNSA）、国际原子能机构（IAEA）、美国核管会（NRC）、英国核安全局（ONR）和法国核安全局（ASN）对新型压水堆核电厂首堆试验的相关要求，本文通过分析欧洲先进压水堆（EPR）机组的新设计理念和新设计特点并结合已建成压水堆核电机组的工程实践，提出了采用控制变量确定选取原则并通过五步选取流程确定首堆试验项目的方法。实践证明，该方法不仅可确保首堆试验选取与确定工作顺利有效的开展，还能使新概念设计和具有新特性物项的性能得到充分和完整的验证，保证了新堆型核电站后期安全稳定地运行，该方法也适用于华龙一号在内的其他压水堆核电技术路线。 

Selection and Practice of First of a Kind Test for EPR Unit

In order to meet the requirements of NNSA, IAEA, NRC, ONR and ASN on the first of a kind test for the new type PWR nuclear power plant, based on the analysis of new design concepts and new design features of the EPR unit and the engineering practice of PWR, this paper proposes a method to determine the first of a kind test by using the control variable selection principle and the five-step selection process. Project practice has proved that this method can ensure the smooth and effective implementation of the commissioning program, and can completely verify the new concept design and the performance of new characteristics, so as to ensure the safe and stable operation of the reactor nuclear power plant. This method can also be applied to other types of PWR nuclear power technology like HPR1000.
