9月26日8時(shi)56分(fen)，在(zai)15名來(lai)自田灣(wan)核(he)電(dian)站周邊(bian)鄉鎮公眾(zhong)代表的注目(mu)(mu)下(xia)，歷時(shi)1小時(shi)58分(fen)，田灣(wan)核(he)電(dian)站4號(hao)機組穹頂吊裝順利完(wan)成(cheng)，標志(zhi)著田灣(wan)核(he)電(dian)二期工(gong)(gong)程提前(qian)26天(tian)從土建(jian)施工(gong)(gong)階(jie)段全(quan)面轉入(ru)設備安裝階(jie)段。4號(hao)機組與同樣擁有(you)“世界最(zui)(zui)大(da)、最(zui)(zui)重薄殼(ke)穹頂”的3號(hao)機組并肩而立，是福島事故后我國核(he)準獲(huo)批開工(gong)(gong)的首個核(he)電(dian)項目(mu)(mu)，也是繼田灣(wan)一期工(gong)(gong)程之后，中俄雙方(fang)繼續深化核(he)能領域合(he)作的又一重大(da)項目(mu)(mu)。

田(tian)灣二期工(gong)(gong)(gong)程(cheng)(cheng)以1、2號機(ji)組為參考電站，繼續采用(yong)俄羅斯設計制造的(de)VVER-1000型反應堆(dui)，并(bing)在一期工(gong)(gong)(gong)程(cheng)(cheng)的(de)基礎上進(jin)行了(le)必要的(de)設計改進(jin)，進(jin)一步提高了(le)機(ji)組的(de)安全性、技術先進(jin)性、經濟型和工(gong)(gong)(gong)程(cheng)(cheng)可實施性。單臺機(ji)組發電功(gong)率110萬千瓦(wa)，建設工(gong)(gong)(gong)期62個月。

4號(hao)機(ji)組(zu)穹(qiong)(qiong)頂吊(diao)(diao)裝(zhuang)(zhuang)既(ji)有傳承也有創新(xin)。本(ben)次吊(diao)(diao)裝(zhuang)(zhuang)沿用(yong)了整體吊(diao)(diao)裝(zhuang)(zhuang)方案，該方案在田灣核電(dian)(dian)站3號(hao)機(ji)組(zu)中被首(shou)次采用(yong)，相較于1、2號(hao)機(ji)組(zu)反應堆廠房(fang)穹(qiong)(qiong)頂球(qiu)帶和球(qiu)冠分兩次吊(diao)(diao)裝(zhuang)(zhuang)，整體吊(diao)(diao)裝(zhuang)(zhuang)能(neng)夠節約近2個月的(de)(de)工(gong)期，并(bing)大大降低(di)了施(shi)工(gong)過程中的(de)(de)安(an)全風(feng)險，是VVER-1000型核電(dian)(dian)機(ji)組(zu)工(gong)程建設史上(shang)的(de)(de)重(zhong)大創新(xin)和里(li)程碑。此次吊(diao)(diao)裝(zhuang)(zhuang)還創造(zao)性地(di)解決了3號(hao)機(ji)組(zu)吊(diao)(diao)裝(zhuang)(zhuang)過程中沒(mei)有遇到的(de)(de)場地(di)不規則、空(kong)間(jian)狹窄、地(di)基(ji)承載力不足等難題，為吊(diao)(diao)臂長(chang)度138米(mi)的(de)(de)3200噸起(qi)重(zhong)機(ji)完成半徑95.2米(mi)的(de)(de)吊(diao)(diao)裝(zhuang)(zhuang)作業創造(zao)了地(di)面和空(kong)間(jian)條件。

本次吊(diao)裝作(zuo)業(ye)是在江(jiang)蘇核(he)電(dian)(dian)有(you)限(xian)公(gong)司(si)(si)統(tong)一協調下，由中(zhong)(zhong)(zhong)國核(he)電(dian)(dian)工(gong)(gong)(gong)(gong)程有(you)限(xian)公(gong)司(si)(si)田灣(wan)核(he)電(dian)(dian)項(xiang)目(mu)(mu)(mu)部(bu)組織(zhi)，北京四(si)達貝克(ke)斯(si)工(gong)(gong)(gong)(gong)程監理有(you)限(xian)公(gong)司(si)(si)田核(he)監理部(bu)、中(zhong)(zhong)(zhong)國核(he)工(gong)(gong)(gong)(gong)業(ye)華興建(jian)設(she)有(you)限(xian)公(gong)司(si)(si)田灣(wan)項(xiang)目(mu)(mu)(mu)部(bu)、中(zhong)(zhong)(zhong)國核(he)工(gong)(gong)(gong)(gong)業(ye)中(zhong)(zhong)(zhong)核(he)機(ji)械工(gong)(gong)(gong)(gong)程有(you)限(xian)公(gong)司(si)(si)田灣(wan)核(he)電(dian)(dian)項(xiang)目(mu)(mu)(mu)部(bu)及中(zhong)(zhong)(zhong)國核(he)工(gong)(gong)(gong)(gong)業(ye)二三(san)建(jian)設(she)公(gong)司(si)(si)連(lian)云港項(xiang)目(mu)(mu)(mu)部(bu)等單位共(gong)同實施，在各(ge)方的通力協作(zuo)下，共(gong)同推進了田灣(wan)核(he)電(dian)(dian)4號機(ji)組穹頂吊(diao)裝的提前(qian)完成(cheng)，縮短了工(gong)(gong)(gong)(gong)程建(jian)設(she)工(gong)(gong)(gong)(gong)期。4號機(ji)組自2013年9月27日開(kai)工(gong)(gong)(gong)(gong)以來，工(gong)(gong)(gong)(gong)程建(jian)設(she)各(ge)節(jie)點目(mu)(mu)(mu)標(biao)均按期或提前(qian)完成(cheng)。

田(tian)灣核電(dian)是中(zhong)俄核能合作(zuo)的(de)標志性(xing)工程。二期工程的(de)順利(li)推進(jin)，有(you)利(li)于進(jin)一步加深(shen)中(zhong)俄兩國政治互信、推動(dong)經貿往來(lai)、加強戰略(lve)合作(zuo)，并將在(zai)持(chi)續(xu)推動(dong)地(di)方(fang)經濟建設和我國核電(dian)事業安全(quan)高(gao)效發(fa)(fa)展(zhan)中(zhong)發(fa)(fa)揮重要(yao)作(zuo)用。
