几十年来，使用积分实验的核数据调整在为反应堆设计人员和燃料循环分析人员提供具有降低和验证的不确定性的核数据方面发挥着至关重要的作用，以便在满足安全和经济要求的同时进行设计优化。应仔细界定调整方法、积分试验的选择和协方差数据评估，以便作出适用于各种系统的可靠和实际上可接受的调整。自2005年以来，经合组织-NEA成立了一系列专家组，以调查关键的科学问题并为应用提供建议。本文件讨论了这些专家组最近取得的主要成果，并指出了前进的道路。
Nuclear data adjustments using integral experiments play since several decades a crucial role in providing reactor designers and fuel cycle analysts with nuclear data with reduced and validated uncertainties in order to allow design optimization while meeting safety and economics requirements. Adjustment methods, choice of integral experiments and covariance data assessment should be carefully defined in order to produce credible and physically acceptable adjustments, applicable to a wide range of systems. The OECD-NEA has established a series of Expert Groups since 2005 to investigate the key scientific issues and to provide recommendations for applications. The present paper discusses the major results of the most recent of these Expert Groups together with an indication of the path forward .
