4月12日(ri)，中國核建承(cheng)建的紅沿(yan)河核電站二期工程再次迎來(lai)了重大節(jie)點(dian)，5號(hao)機組順(shun)利實現(xian)穹(qiong)頂吊裝(zhuang)，正式由土建施工轉入安(an)裝(zhuang)階段。
早(zao)上(shang)6時，隨著吊裝總(zong)指(zhi)揮(hui)的一(yi)(yi)聲(sheng)令(ling)下，重達(da)166噸的穹頂由CC6800型吊機緩緩吊起(qi)，通過旋轉(zhuan)、落鉤、變幅、回轉(zhuan)等一(yi)(yi)系列施工，于7時2分成(cheng)功吊裝就位，安全質量進度滿足要(yao)求。
紅(hong)沿(yan)河核(he)電(dian)(dian)站(zhan)位于遼寧大連瓦房店(dian)市，規劃建設(she)(she)六臺百(bai)萬千瓦級核(he)電(dian)(dian)機(ji)組(zu)。其中，一(yi)期(qi)(qi)工(gong)(gong)程四臺機(ji)組(zu)已全面建成，采用(yong)CPR1000壓水堆核(he)電(dian)(dian)技術(shu)。二期(qi)(qi)工(gong)(gong)程建設(she)(she)兩臺機(ji)組(zu)，采用(yong)ACPR1000核(he)電(dian)(dian)技術(shu)。二期(qi)(qi)工(gong)(gong)程5/6號機(ji)組(zu)施工(gong)(gong)方案進一(yi)步優化，在(zai)CPR1000技術(shu)方案的基礎上增(zeng)加(jia)了3項(xiang)非能動設(she)(she)計(ji)(ji)改(gai)進，擁有應對類似福島的超(chao)設(she)(she)計(ji)(ji)基準事故工(gong)(gong)況的能力。
5號機組于2015年3月29日正(zheng)式開(kai)工(gong)(gong)(gong)(gong)建設(she)(she)，自(zi)開(kai)工(gong)(gong)(gong)(gong)以來，面對上游設(she)(she)備滯后、設(she)(she)計變更等困(kun)難及大風、嚴寒等不利因素，中核華興紅沿(yan)河(he)核電項(xiang)目統籌(chou)策(ce)劃，精心施(shi)(shi)工(gong)(gong)(gong)(gong)，優化施(shi)(shi)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝和工(gong)(gong)(gong)(gong)序。為確保此次(ci)穹頂吊裝的(de)順利實現，項(xiang)目部根據(ju)一期工(gong)(gong)(gong)(gong)程施(shi)(shi)工(gong)(gong)(gong)(gong)經(jing)驗，結合紅沿(yan)河(he)核電實際，提前策(ce)劃, 精密部署，制定了詳(xiang)實的(de)吊裝方案，積極跟蹤(zong)施(shi)(shi)工(gong)(gong)(gong)(gong)重點(dian)，妥(tuo)善解(jie)決(jue)施(shi)(shi)工(gong)(gong)(gong)(gong)難點(dian)，最終保證穹頂吊裝工(gong)(gong)(gong)(gong)作圓滿完成。
