10月(yue)19日17時42分，歷(li)時14天，國家科技重大專(zhuan)項——全球(qiu)首座(zuo)高(gao)溫氣冷堆(dui)核(he)電(dian)示范(fan)工程首堆(dui)一(yi)(yi)回路冷態功能試驗一(yi)(yi)次成功。

不同于其他堆型的(de)(de)冷態功(gong)能(neng)試(shi)驗(yan)，高(gao)(gao)溫(wen)氣冷堆核電示范工(gong)程(cheng)(cheng)(cheng)冷態功(gong)能(neng)試(shi)驗(yan)采(cai)用壓(ya)縮空氣作(zuo)為(wei)試(shi)驗(yan)介質，分臺階(jie)加壓(ya)至最(zui)高(gao)(gao)試(shi)驗(yan)壓(ya)力8.9MPa進行一回(hui)路壓(ya)力邊(bian)界強度性能(neng)試(shi)驗(yan)，然后(hou)降至8.0MPa保(bao)壓(ya)24小時以上測量一回(hui)路泄(xie)漏(lou)率，同時考察一回(hui)路壓(ya)力容器(qi)在(zai)壓(ya)力作(zuo)用下的(de)(de)變形和(he)位移，并對支承(cheng)系統的(de)(de)有效性作(zuo)出(chu)初步(bu)判斷。試(shi)驗(yan)結(jie)果表明，示范工(gong)程(cheng)(cheng)(cheng)首堆各項指標(biao)均滿足設(she)計要求，有效檢驗(yan)了示范工(gong)程(cheng)(cheng)(cheng)核島設(she)備制造和(he)安(an)裝質量的(de)(de)可靠性，為(wei)加快高(gao)(gao)溫(wen)氣冷堆產業(ye)化推(tui)廣，實現全球第四代核電技術引領(ling)邁出(chu)了關鍵一步(bu)。

為(wei)確保(bao)冷試節(jie)點的順(shun)(shun)利(li)(li)實現(xian)，面(mian)對突如其來的新冠肺炎疫(yi)情(qing)，中(zhong)核能源迅速理順(shun)(shun)全(quan)年(nian)工(gong)(gong)(gong)(gong)作計(ji)劃及重(zhong)難點，大力采(cai)取施(shi)工(gong)(gong)(gong)(gong)激勵措施(shi)，加強現(xian)場(chang)施(shi)工(gong)(gong)(gong)(gong)管(guan)理，充分調(diao)動(dong)起(qi)現(xian)場(chang)項目(mu)部和施(shi)工(gong)(gong)(gong)(gong)單位的生(sheng)產積極性。圍繞(rao)冷試先決條件(jian)和全(quan)年(nian)工(gong)(gong)(gong)(gong)作目(mu)標，中(zhong)核能源現(xian)場(chang)項目(mu)部開啟全(quan)員全(quan)時段工(gong)(gong)(gong)(gong)作模式，帶領現(xian)場(chang)施(shi)工(gong)(gong)(gong)(gong)團隊(dui)順(shun)(shun)利(li)(li)完(wan)成三殼(ke)組對、主氦風(feng)機(ji)安裝、電纜敷(fu)設(she)、燃料裝卸系統改造、反(fan)應堆廠房封閉、應急柴油機(ji)安裝等重(zhong)大工(gong)(gong)(gong)(gong)程節(jie)點目(mu)標，一回路壓(ya)力試驗(yan)相關系統全(quan)部按期移交(jiao)調(diao)試，為(wei)實現(xian)示(shi)范工(gong)(gong)(gong)(gong)程首堆冷試目(mu)標提(ti)供了(le)有(you)力保(bao)障。

中核二三公司高溫堆(dui)項目(mu)部(bu)(bu)在常態(tai)化做好(hao)疫情(qing)防控工作的同時，全面落實(shi)質量控制、安(an)全值守、進度保障(zhang)等要求，黨員帶(dai)頭踐行“我(wo)為冷試(shi)(shi)做貢(gong)獻”行動，全員投(tou)入，協同攻(gong)堅(jian)(jian)，先后打贏了“雙堆(dui)三殼組對”“雙堆(dui)主氦風機安(an)裝試(shi)(shi)車”等關鍵(jian)節點的攻(gong)堅(jian)(jian)戰，高質量按時完成(cheng)首(shou)堆(dui)冷試(shi)(shi)全部(bu)(bu)系(xi)統移交，為首(shou)堆(dui)冷試(shi)(shi)一次成(cheng)功奠(dian)定了堅(jian)(jian)實(shi)基礎。

目(mu)前(qian)，高溫氣冷堆核電示范(fan)工程第二臺反應堆一(yi)回路冷態(tai)功能試驗也已于10月19日凌晨開(kai)始。“雙(shuang)堆冷試”年度目(mu)標的實現(xian)，將為后續熱(re)態(tai)功能試驗及裝料奠定(ding)堅實基礎。
