3月13日(ri)，白鶴灘(tan)水電站順利(li)通過蓄水前樞紐工程安全鑒(jian)定，標(biao)志著向(xiang)“七(qi)一”蓄水發(fa)電目標(biao)又(you)邁出堅實(shi)一步(bu)。

蓄(xu)(xu)水(shui)前安全(quan)(quan)鑒定是對白鶴灘(tan)水(shui)電站樞紐工程建設全(quan)(quan)過程的(de)(de)(de)全(quan)(quan)面(mian)檢查(cha)，是對工程蓄(xu)(xu)水(shui)條(tiao)件的(de)(de)(de)總體評價，是蓄(xu)(xu)水(shui)驗收(shou)的(de)(de)(de)重要前置程序。

為做好此次安(an)全(quan)鑒(jian)定，中國水利水電(dian)建(jian)設(she)工(gong)(gong)(gong)(gong)程(cheng)(cheng)咨詢(xun)有限公司組織了涵(han)蓋水工(gong)(gong)(gong)(gong)、防洪(hong)、地質(zhi)、施(shi)工(gong)(gong)(gong)(gong)、金結、監(jian)(jian)測(ce)等6大(da)專業，由(you)26名專家(jia)組成的專家(jia)組。從3月2日專家(jia)組啟動(dong)工(gong)(gong)(gong)(gong)作以(yi)來，通過資料閱研和(he)現場(chang)查勘，并(bing)與工(gong)(gong)(gong)(gong)程(cheng)(cheng)參建(jian)各方充分討論(lun)交流(liu)(liu)，經過歷(li)時12天的持續工(gong)(gong)(gong)(gong)作，形(xing)成了蓄水前(qian)安(an)全(quan)鑒(jian)定結論(lun)意見：“白(bai)鶴灘(tan)(tan)水電(dian)站(zhan)樞(shu)(shu)紐(niu)工(gong)(gong)(gong)(gong)程(cheng)(cheng)建(jian)設(she)形(xing)象(xiang)面(mian)貌和(he)計(ji)(ji)劃安(an)排可(ke)滿足2021年(nian)4月導(dao)流(liu)(liu)底(di)孔(kong)下(xia)閘、水庫蓄水以(yi)及2021年(nian)汛(xun)(xun)期防洪(hong)度汛(xun)(xun)形(xing)象(xiang)面(mian)貌要求(qiu)。白(bai)鶴灘(tan)(tan)水電(dian)站(zhan)樞(shu)(shu)紐(niu)工(gong)(gong)(gong)(gong)程(cheng)(cheng)建(jian)筑(zhu)物設(she)計(ji)(ji)符(fu)合規范規定；已完土建(jian)工(gong)(gong)(gong)(gong)程(cheng)(cheng)、金屬(shu)結構工(gong)(gong)(gong)(gong)程(cheng)(cheng)、安(an)全(quan)監(jian)(jian)測(ce)工(gong)(gong)(gong)(gong)程(cheng)(cheng)的施(shi)工(gong)(gong)(gong)(gong)及制造(zao)和(he)安(an)裝質(zhi)量總(zong)體滿足設(she)計(ji)(ji)、國家(jia)和(he)行(xing)業有關(guan)技術標準(zhun)及工(gong)(gong)(gong)(gong)程(cheng)(cheng)合同文件(jian)的要求(qiu)。設(she)計(ji)(ji)復核及已有監(jian)(jian)測(ce)成果表明，大(da)壩等樞(shu)(shu)紐(niu)建(jian)筑(zhu)物工(gong)(gong)(gong)(gong)作性態正常，工(gong)(gong)(gong)(gong)程(cheng)(cheng)區邊坡和(he)近壩庫岸整體穩定，導(dao)流(liu)(liu)底(di)孔(kong)過流(liu)(liu)正常。導(dao)流(liu)(liu)底(di)孔(kong)下(xia)閘方案、水庫初期蓄水方案、工(gong)(gong)(gong)(gong)程(cheng)(cheng)防洪(hong)度汛(xun)(xun)方案和(he)措施(shi)總(zong)體可(ke)行(xing)，導(dao)流(liu)(liu)底(di)孔(kong)下(xia)閘準(zhun)備(bei)工(gong)(gong)(gong)(gong)作基本就緒(xu)。據此，白(bai)鶴灘(tan)(tan)水電(dian)站(zhan)樞(shu)(shu)紐(niu)工(gong)(gong)(gong)(gong)程(cheng)(cheng)具備(bei)導(dao)流(liu)(liu)底(di)孔(kong)下(xia)閘蓄水的條件(jian)。”

此次(ci)安全鑒定(ding)(ding)過程(cheng)(cheng)中，3月11日(ri)至16日(ri)還同步開展(zhan)了工程(cheng)(cheng)輸水(shui)(shui)(shui)發(fa)電(dian)系(xi)統專項(xiang)安全鑒定(ding)(ding)現場檢查。現場檢查意見認為(wei)，“白(bai)鶴(he)灘(tan)水(shui)(shui)(shui)電(dian)站輸水(shui)(shui)(shui)發(fa)電(dian)系(xi)統工程(cheng)(cheng)已基本具備尾水(shui)(shui)(shui)系(xi)統充(chong)水(shui)(shui)(shui)條(tiao)件，以及(ji)2021年5月實施首批機組(zu)(zu)引(yin)水(shui)(shui)(shui)系(xi)統充(chong)水(shui)(shui)(shui)的條(tiao)件，機組(zu)(zu)段充(chong)水(shui)(shui)(shui)可根據機組(zu)(zu)安裝調試要求適時安排。”標志(zhi)著白(bai)鶴(he)灘(tan)工程(cheng)(cheng)已具備開展(zhan)機組(zu)(zu)啟動驗收(shou)的條(tiao)件。

后續，工(gong)程蓄水驗(yan)收(shou)委員會將(jiang)在(zai)此次安全(quan)鑒(jian)定(ding)和同期開展的(de)專項質(zhi)量監督結論意見的(de)基礎(chu)上，組織工(gong)程蓄水驗(yan)收(shou)工(gong)作。白(bai)鶴灘(tan)水電站已做好蓄水發電準備，進入“七一”發電倒(dao)計(ji)時。
