9月26日8時(shi)56分(fen)，在15名來自(zi)田灣(wan)核電(dian)(dian)站周邊鄉鎮公(gong)眾代表的注目下，歷時(shi)1小時(shi)58分(fen)，田灣(wan)核電(dian)(dian)站4號機(ji)(ji)組(zu)穹頂(ding)吊裝順利(li)完(wan)成，標志(zhi)著田灣(wan)核電(dian)(dian)二(er)期工(gong)程提前26天(tian)從土(tu)建施(shi)工(gong)階(jie)段全面轉入(ru)設備(bei)安(an)裝階(jie)段。4號機(ji)(ji)組(zu)與同樣(yang)擁(yong)有“世界最(zui)大(da)、最(zui)重薄(bo)殼穹頂(ding)”的3號機(ji)(ji)組(zu)并肩而(er)立，是福島事(shi)故后(hou)我國核準獲批(pi)開工(gong)的首個核電(dian)(dian)項(xiang)目，也(ye)是繼(ji)田灣(wan)一期工(gong)程之后(hou)，中俄雙方繼(ji)續深化(hua)核能領域合作的又一重大(da)項(xiang)目。

田灣二(er)期(qi)工程以1、2號機(ji)組為參(can)考電(dian)(dian)站，繼(ji)續采用俄羅(luo)斯設(she)計(ji)制造的VVER-1000型反應(ying)堆，并在一期(qi)工程的基礎上進行了必(bi)要的設(she)計(ji)改進，進一步提高了機(ji)組的安全(quan)性(xing)、技術(shu)先進性(xing)、經(jing)濟型和(he)工程可實施性(xing)。單(dan)臺機(ji)組發(fa)電(dian)(dian)功率(lv)110萬千瓦，建設(she)工期(qi)62個月(yue)。

4號(hao)(hao)機(ji)組(zu)穹頂(ding)吊(diao)(diao)(diao)(diao)裝既有傳承也(ye)有創新(xin)。本次吊(diao)(diao)(diao)(diao)裝沿用(yong)了(le)整體吊(diao)(diao)(diao)(diao)裝方(fang)案，該方(fang)案在(zai)田灣核(he)電站3號(hao)(hao)機(ji)組(zu)中被首次采(cai)用(yong)，相較于1、2號(hao)(hao)機(ji)組(zu)反應堆廠房穹頂(ding)球帶(dai)和(he)球冠分兩次吊(diao)(diao)(diao)(diao)裝，整體吊(diao)(diao)(diao)(diao)裝能夠節約(yue)近2個月的工(gong)(gong)期，并大大降低了(le)施工(gong)(gong)過程中的安全風險(xian)，是VVER-1000型核(he)電機(ji)組(zu)工(gong)(gong)程建設史上的重(zhong)大創新(xin)和(he)里程碑。此(ci)次吊(diao)(diao)(diao)(diao)裝還(huan)創造(zao)性地解決了(le)3號(hao)(hao)機(ji)組(zu)吊(diao)(diao)(diao)(diao)裝過程中沒有遇到的場地不(bu)(bu)規則、空(kong)間狹窄、地基承載力不(bu)(bu)足等難題(ti)，為(wei)吊(diao)(diao)(diao)(diao)臂長度(du)138米(mi)的3200噸起重(zhong)機(ji)完成半(ban)徑(jing)95.2米(mi)的吊(diao)(diao)(diao)(diao)裝作業創造(zao)了(le)地面和(he)空(kong)間條件(jian)。

本次(ci)吊裝作業(ye)是(shi)在江蘇核(he)(he)電(dian)有(you)限(xian)(xian)(xian)公司統一協(xie)調(diao)下(xia)，由中(zhong)(zhong)(zhong)國核(he)(he)電(dian)工(gong)(gong)(gong)程有(you)限(xian)(xian)(xian)公司田(tian)(tian)灣(wan)核(he)(he)電(dian)項(xiang)目部組(zu)(zu)織，北(bei)京四達貝克(ke)斯工(gong)(gong)(gong)程監理有(you)限(xian)(xian)(xian)公司田(tian)(tian)核(he)(he)監理部、中(zhong)(zhong)(zhong)國核(he)(he)工(gong)(gong)(gong)業(ye)華興建(jian)(jian)(jian)設(she)有(you)限(xian)(xian)(xian)公司田(tian)(tian)灣(wan)項(xiang)目部、中(zhong)(zhong)(zhong)國核(he)(he)工(gong)(gong)(gong)業(ye)中(zhong)(zhong)(zhong)核(he)(he)機(ji)械工(gong)(gong)(gong)程有(you)限(xian)(xian)(xian)公司田(tian)(tian)灣(wan)核(he)(he)電(dian)項(xiang)目部及中(zhong)(zhong)(zhong)國核(he)(he)工(gong)(gong)(gong)業(ye)二三(san)建(jian)(jian)(jian)設(she)公司連云港項(xiang)目部等單位共(gong)同實(shi)施(shi)，在各(ge)方的通力協(xie)作下(xia)，共(gong)同推進了田(tian)(tian)灣(wan)核(he)(he)電(dian)4號(hao)機(ji)組(zu)(zu)穹頂吊裝的提前完(wan)成，縮短了工(gong)(gong)(gong)程建(jian)(jian)(jian)設(she)工(gong)(gong)(gong)期(qi)。4號(hao)機(ji)組(zu)(zu)自2013年9月27日開工(gong)(gong)(gong)以來，工(gong)(gong)(gong)程建(jian)(jian)(jian)設(she)各(ge)節點目標(biao)均(jun)按(an)期(qi)或(huo)提前完(wan)成。

田灣核電是(shi)中俄核能合(he)作(zuo)的(de)標(biao)志性工程。二期工程的(de)順利(li)推(tui)進，有(you)利(li)于進一(yi)步加(jia)深中俄兩國(guo)政治互信、推(tui)動經貿往來、加(jia)強戰略合(he)作(zuo)，并將在持續(xu)推(tui)動地方(fang)經濟建設(she)和我(wo)國(guo)核電事(shi)業安全高效發展中發揮重要作(zuo)用。

江蘇省、連(lian)云港(gang)市等地方政府和(he)有關部(bu)門(men)，國家核安(an)全監管部(bu)門(men)，以及股東方、監理公司、中外(wai)參建(jian)單位(wei)的領導和(he)代表現場觀摩(mo)了(le)本次(ci)吊(diao)裝(zhuang)作業。
