7月(yue)21日0時5分，由中國能建(jian)天津(jin)電建(jian)參(can)建(jian)、廣東院(yuan)參(can)與設計的(de)我(wo)國首(shou)座海島核電工(gong)程(cheng)——福建(jian)寧德核電站(zhan)4號(hao)機組(zu)順利通過168小時試運(yun)行，具備商運(yun)條件，標志著寧德核電站(zhan)一(yi)期工(gong)程(cheng)建(jian)設圓滿完成。

寧德核電4號機組(zu)(zu)于7月14日0點5分開(kai)始(shi)進入168小時示范運(yun)行試驗階段。在此期(qi)間，機組(zu)(zu)完成了汽(qi)輪機額定出力性(xing)(xing)能考核試驗、蒸汽(qi)發(fa)生(sheng)器濕度測(ce)量試驗、廠用電率等(deng)系列性(xing)(xing)能考核試驗，機組(zu)(zu)啟動期(qi)間未(wei)發(fa)生(sheng)非(fei)計劃停機停堆事(shi)件，整(zheng)體運(yun)行狀態良(liang)好(hao)。

寧(ning)德(de)核電(dian)工程從2008年2月(yue)18日1號機(ji)組開工，到(dao)今天4號機(ji)組具(ju)備商運(yun)條件，歷時(shi)八年，寧(ning)德(de)核電(dian)一期(qi)項(xiang)(xiang)目全面建成。寧(ning)德(de)核電(dian)一期(qi)項(xiang)(xiang)目實施了“18個月(yue)換料”、“廠(chang)址附(fu)加后備電(dian)源柴(chai)油(you)發(fa)電(dian)機(ji)組設(she)計改進(jin)”等16項(xiang)(xiang)重大技術(shu)改進(jin)，率先(xian)使用的自(zi)主化全范(fan)圍模擬機(ji)達到(dao)國際先(xian)進(jin)水平，主管道自(zi)動焊打破國外技術(shu)封(feng)鎖，項(xiang)(xiang)目綜(zong)合國產化率達到(dao)80%，為帶動我(wo)國核電(dian)產業鏈整體(ti)自(zi)主化能力提(ti)升具(ju)有重要意義。
