| 摘 要： | 本文针对LOFTL2-5整体试验,用先进热工水力程序RELAP5/MOD3对其进行最佳估算模拟,分析验证了程序预测事故过程的能力;同时按照美国核管会10CFR50.46附录K的认证评价模型要求修改RELAP5/MOD3相关模型并进行模拟计算,通过对比程序修改前后对于预测值保守性的影响,分析了保守计算的PGT安全裕量,其结果可为验证并开发认证级LOCA安全分析工具提供参考.

| Abstract: | A best estimate calculation with advanced thermal-hydraulic program REALP5/MOD3 is made for integral test LOFT L2-5 to analyze and verify accident prediction ability of the program. Meanwhile,modifications on related models of the program have been made in compliance with the requirement of licensing evaluation models recommended by USNRC 10CFR50.46,Appendix K,with which simulation on LOFT L2-5 is carried out.By comparing conservatisms of calculation with original program and the modified one,analysis on safety margin of PCT prediction is delivered.The results may provide some references for verification and development of licensing LOCA safety analyzing tools. |
