摘要

Defining and achieving reasonable confidence in the validation of nuclear power plant control room designs is a complex challenge for many reasons: not the least of which is that validation is a test of strength rather than a test of truth. In 2015, the Nuclear Energy Agency, Committee for Safety of Nuclear Installations' Working Group on Human and Organizational Factors (WGHOF) hosted an experts' workshop to identify and critically examine potential means to address the challenge of achieving reasonable confidence in control room design validations. The experts' principal task was to answer four challenge questions. (1) What are the critical considerations in defining validation objectives and how do these impact achieving reasonable confidence? (2) What methods, approaches, resources, or rationales might be used for deriving performance requirements, selecting measures, and establishing acceptance criteria so as to support reasonable confidence? (3) What methods might be used to develop scenarios that maximize the amount and relevance of information in support of the validation conclusions and achieving reasonable confidence? (4) How should the validation results be aggregated and analyzed to determine the final validation conclusions? This paper provides an overview of the experts' responses to these challenges and briefly touches upon their implications for future directions.

(2)什么方法,途径,资源或理由可能被用于导出性能要求,选择的措施,并建立验收标准,以支持合理的信心? (3)可以使用什么方法来开发的方案,最大限度地支持验证结论,并实现合理信心的数量和信息的相关性? (4)应如何验证结果进行汇总和分析,以确定最终验证的结论?本文提供了专家们的这些挑战,并简要介绍了在他们的影响对未来发展方向的反应的概述。
