4月(yue)12日，中國核建承建的紅(hong)沿河(he)核電站二(er)期工程(cheng)再(zai)次迎來了重大節點，5號機組順(shun)利實(shi)現穹頂吊(diao)裝，正式由土建施工轉(zhuan)入安裝階(jie)段。
早上6時，隨著吊裝總指揮的一聲令下，重達166噸的穹頂由CC6800型吊機緩(huan)緩(huan)吊起，通過(guo)旋轉(zhuan)、落(luo)鉤(gou)、變(bian)幅、回轉(zhuan)等一系(xi)列施工，于7時2分成功吊裝就位，安全質量進度滿足要求。
紅沿河核電(dian)站(zhan)位于遼寧大連(lian)瓦房店市，規劃建(jian)設(she)(she)六臺百萬千瓦級核電(dian)機(ji)組(zu)。其中，一期(qi)(qi)工程(cheng)(cheng)四(si)臺機(ji)組(zu)已全(quan)面建(jian)成(cheng)，采用CPR1000壓水堆核電(dian)技術。二(er)期(qi)(qi)工程(cheng)(cheng)建(jian)設(she)(she)兩臺機(ji)組(zu)，采用ACPR1000核電(dian)技術。二(er)期(qi)(qi)工程(cheng)(cheng)5/6號機(ji)組(zu)施(shi)工方案(an)進一步(bu)優(you)化(hua)，在CPR1000技術方案(an)的基礎上增加了3項非能動(dong)設(she)(she)計改進，擁有應對類似福島的超設(she)(she)計基準事故(gu)工況的能力。
5號機組于(yu)2015年3月29日正式開(kai)工(gong)(gong)(gong)(gong)(gong)建設(she)，自開(kai)工(gong)(gong)(gong)(gong)(gong)以來，面對上游設(she)備滯后、設(she)計(ji)變更等困難及大風、嚴寒等不(bu)利因(yin)素，中核(he)華興紅沿(yan)河核(he)電項(xiang)目統籌策劃(hua)，精心施(shi)工(gong)(gong)(gong)(gong)(gong)，優化施(shi)工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)藝和工(gong)(gong)(gong)(gong)(gong)序。為確保(bao)此次穹頂吊裝(zhuang)的順(shun)利實(shi)現(xian)，項(xiang)目部(bu)(bu)根據一期工(gong)(gong)(gong)(gong)(gong)程施(shi)工(gong)(gong)(gong)(gong)(gong)經驗，結(jie)合紅沿(yan)河核(he)電實(shi)際，提前策劃(hua), 精密(mi)部(bu)(bu)署，制定了詳(xiang)實(shi)的吊裝(zhuang)方案，積極(ji)跟(gen)蹤(zong)施(shi)工(gong)(gong)(gong)(gong)(gong)重點，妥善解決施(shi)工(gong)(gong)(gong)(gong)(gong)難點，最終保(bao)證穹頂吊裝(zhuang)工(gong)(gong)(gong)(gong)(gong)作圓滿完(wan)成。
