“华龙一号”首堆示范工程堆内构件流致振动试验影响总工期问题对策研究

“华龙一号”首堆示范工程作为原型堆须按《预运行和初始启动试验期间堆内构件流致振动综合评价大纲（RG1.20）》要求开展堆内构件流致振动堆内实测工作，经评估由此将引起关键路径增加约2.7个月的总工期。为消除试验相关工作对工期的影响，本文采用关键路径分析法对影响因素、应对措施、风险以及采取措施后的关联影响进行分析，提出可行的优化方案。分析结果表明，通过采取对关键路径工作的逻辑、工期进行优化调整方法后，可以消除试验对“华龙一号”首堆示范工程62个月总工期的影响。 

Study on Countermeasures for Effect of Flow-Induced Vibration Test of Reactor Internals in First Demonstration Project of HPR1000?on Total Construction Period

As the FOAK, HPR1000 is required to carry out the in-reactor measurement of flow induced vibration of reactor internals based on the regulation Comprehensive Vibration Assessment Program for Reactor Internals during Pre-operational and Start-up Testing (RG1.20) . The evaluation shows that this will result in additional 2.7 mouths in the construction period in the critical path. In order to eliminate the effect of test-related work on the construction period, this paper proposes a feasible optimization scheme by analyzing the influencing factors, countermeasures, risks and the associated effects after taking these measures. The analysis results indicate that the effect of test-related work on the construction period (62 months) of FOAK project can be eliminated by adjusting the logic of critical path and duration optimization.
