21日15时9分,我国自主三代核电“华龙一号”全球首堆——中核集团福清核电5号机组首次达到临界状态,标志着机组正式进入带功率运行状态,向建成投产迈出了重要一步。

据介绍,核电站核反应堆临界类似常规火电厂锅炉的点火过程,也如同心脏起搏。临界后,作为反应堆的“心脏”——堆芯将开始持续“跳动”,反应堆处于带核平衡运作状态。

经国家核安全局批准,华东核与辐射安全监督站核查释放,福清核电5号机组开始反应堆达临界操作。通过稀释一回路硼浓度和提升控制棒操作,反应堆首次达到临界状态。

机组临界过程中,福清核电及各参建单位严格按照技术规程操作,全过程平稳有序,系统运行参数正常。

“华龙一号”全球首堆首次达到临界状态

21日15时9分,我国自主三代核电“华龙一号”全球首堆——中核集团福清核电5号机组首次达到临界状态,标志着机组正式进入带功率运行状态,向建成投产迈出了重要一步。

据介绍,核电站核反应堆临界类似常规火电厂锅炉的点火过程,也如同心脏起搏。临界后,作为反应堆的“心脏”——堆芯将开始持续“跳动”,反应堆处于带核平衡运作状态。

经国家核安全局批准,华东核与辐射安全监督站核查释放,福清核电5号机组开始反应堆达临界操作。通过稀释一回路硼浓度和提升控制棒操作,反应堆首次达到临界状态。
