摘　　要：随着自主三代核电技术的稳步推进,在建核电项目面临控制系统逻辑验证量大、工期长的问题,而现有验证方案源于二代加核电项目,限制了逻辑验证效率的提升。针对此问题,对国内二代加、自主三代核电项目的控制逻辑特点和验证策略进行分析和归纳,以总结现有方案在工程实践中存在的问题。在此基础上,从验证策略、组织模式、实施方法三个维度研究应对措施,提出了重构逻辑测试场景、引入仿真技术、建立自动化测试系统的改进方案。改进方案和原方案的效益对比结果表明,改进方案的工作量和工期均大幅减少。改进方案提升了逻辑验证的实施效率和工程效益,对工程实际问题提出了针对性解决措施。该研究对后续批量化推进三代核电项目工程建设具有参考价值。With the steady progress of independent third-generation nuclear power technology,nuclear power projects under construction are facing the problems of large volume and long duration of control system logic verification,while the existing verification scheme originates from the second-generation plus nuclear power projects,which restricts the enhancement of the logic verification efficiency.To address this problem,the control logic characteristics and verification strategies of the domestic second-generation plus and autonomous third-generation nuclear power projects are analyzed and summarized to summarize the problems of the existing schemes in engineering practice.On this basis,the countermeasures are studied from three dimensions of verification strategy,organization mode,and implementation method,and the improvement scheme of reconstructing logic test scenarios,introducing simulation technology,and establishing automated test system is proposed.The benefit comparision results between the improvement scheme and the original scheme shows that the workload and duration of the improvement scheme are reduced significantly.The improvement scheme enhances the implementation efficiency and engineering benefits of logic verification and puts forward targeted solution measures for actual engineering problems.The research is of reference value for the subsequent batch promotion of the engineering construction of third-generation nuclear power projects.
