大亚湾核电站18个月换料启动物理试验改进

Improvements on Startup Physics Test Program for Daya Bay Nuclear Power Station with 18 Months Fuel Cycle

综述了大亚湾核电站实施18个月换料和低泄漏堆芯装载方案后,启动物理试验技术和试验方案的改进,并给出对试验结果的分析和评价。

The paper issues the improvements on the test technology and program for Daya Nuclear Power Station startup physics tests, and gives the analysis and evaluation for test results. It's proved the success for the execution of 18-month fuel cycle project. It's also valuable as a reference to other nuclear power plants in the respect of startup physics test, which would change the loading pattern to low leakage reload.
