近日，隨著整體(ti)頂蓋的(de)(de)鍛造(zao)結束，國(guo)(guo)(guo)內首套(tao)ACPR50S實(shi)驗(yan)堆(dui)全(quan)套(tao)反(fan)應堆(dui)壓力容器鍛件在國(guo)(guo)(guo)機集(ji)團所屬(shu)國(guo)(guo)(guo)機重型裝(zhuang)(zhuang)備集(ji)團股份有限公(gong)司(si)（以下簡(jian)稱“國(guo)(guo)(guo)機重裝(zhuang)(zhuang)”）二重裝(zhuang)(zhuang)備完成了鍛造(zao)工序(xu)。該(gai)實(shi)驗(yan)堆(dui)是(shi)(shi)我國(guo)(guo)(guo)自(zi)主設(she)(she)計(ji)的(de)(de)、具有完全(quan)自(zi)主知識產權的(de)(de)一種(zhong)新型海(hai)上浮動(dong)反(fan)應堆(dui)，也是(shi)(shi)我國(guo)(guo)(guo)海(hai)上浮動(dong)核(he)電站建設(she)(she)領域的(de)(de)首堆(dui)。
ACPR50S實驗堆壓力容(rong)器(qi)鍛件主要(yao)包括：整體頂蓋(gai)、下(xia)封頭、法蘭接管段(duan)筒(tong)(tong)體、堆芯(xin)段(duan)筒(tong)(tong)體。整套鍛件是(shi)二(er)重(zhong)裝(zhuang)備首(shou)次(ci)承制(zhi)，且均(jun)需評定(ding)，技術指標要(yao)求嚴格，制(zhi)造難度大。
該項(xiang)目(mu)從運行(xing)之初，就(jiu)受(shou)到了二重(zhong)裝備高度重(zhong)視。前(qian)期，鑄(zhu)鍛(duan)(duan)所工(gong)(gong)(gong)(gong)藝人(ren)(ren)(ren)員對產(chan)品圖紙、技(ji)術資料進行(xing)了仔(zi)細消化(hua)，并針(zhen)對技(ji)術條件(jian)中一些難點問題、嚴(yan)苛要求及(ji)時與用戶溝通。為實現(xian)(xian)異形件(jian)的(de)(de)仿形鍛(duan)(duan)造(zao)，工(gong)(gong)(gong)(gong)藝人(ren)(ren)(ren)員通過(guo)(guo)設(she)計(ji)工(gong)(gong)(gong)(gong)裝并結合計(ji)算機模擬手段(duan)不(bu)斷對工(gong)(gong)(gong)(gong)藝過(guo)(guo)程進行(xing)優(you)化(hua)。今年四月中旬，各工(gong)(gong)(gong)(gong)件(jian)相(xiang)繼(ji)開始投(tou)料，進入生(sheng)產(chan)階段(duan)。在(zai)生(sheng)產(chan)過(guo)(guo)程中，為確保產(chan)品制造(zao)的(de)(de)工(gong)(gong)(gong)(gong)藝可靠性及(ji)操(cao)作現(xian)(xian)場的(de)(de)工(gong)(gong)(gong)(gong)藝執(zhi)行(xing)性，鑄(zhu)鍛(duan)(duan)所牽頭組織了系統性工(gong)(gong)(gong)(gong)藝評審，會(hui)同相(xiang)關車間(jian)進行(xing)了詳細的(de)(de)工(gong)(gong)(gong)(gong)藝交底，并在(zai)鍛(duan)(duan)前(qian)對整個鍛(duan)(duan)造(zao)過(guo)(guo)程進行(xing)風險(xian)識(shi)別，編制詳細的(de)(de)風險(xian)防范措施(shi)。在(zai)制造(zao)環節中，工(gong)(gong)(gong)(gong)藝技(ji)術人(ren)(ren)(ren)員進行(xing)了全面、及(ji)時的(de)(de)現(xian)(xian)場技(ji)術服務(wu)，保證(zheng)了項(xiang)目(mu)的(de)(de)順利推進。
