4月26日凌晨02:09分，中國(guo)核建(jian)(jian)中核五(wu)公司(si)承(cheng)建(jian)(jian)的巴基斯坦恰(qia)希(xi)瑪(ma)核電二號(hao)機組（以下(xia)簡稱(cheng)C2機組）滿功率試(shi)驗(yan)(yan)各(ge)項參數穩定，滿功率試(shi)驗(yan)(yan)重大(da)里程(cheng)碑節點提前完成，標志(zhi)著巴基斯坦恰(qia)希(xi)瑪(ma)核電二號(hao)機組由中方(fang)調試(shi)階(jie)段轉向巴方(fang)臨(lin)時驗(yan)(yan)收階(jie)段。
自(zi)2011年(nian)3月14日C2機(ji)(ji)組(zu)首次并網成(cheng)功(gong)(gong)(gong)以來，參建單(dan)位一步步順利實現了15%、30%、50%、75%電(dian)(dian)(dian)功(gong)(gong)(gong)率(lv)負荷(he)臺階試(shi)驗(yan)(yan)(yan)(yan)(yan)，先后(hou)(hou)完成(cheng)了汽輪機(ji)(ji)機(ji)(ji)械超速(su)(su)和電(dian)(dian)(dian)超速(su)(su)試(shi)驗(yan)(yan)(yan)(yan)(yan)、反應堆功(gong)(gong)(gong)率(lv)手自(zi)動(dong)(dong)切換試(shi)驗(yan)(yan)(yan)(yan)(yan)、功(gong)(gong)(gong)率(lv)量(liang)程核(he)測(ce)儀(yi)表校正(zheng)試(shi)驗(yan)(yan)(yan)(yan)(yan)、電(dian)(dian)(dian)站主要參數設(she)計值確(que)認校正(zheng)試(shi)驗(yan)(yan)(yan)(yan)(yan)、汽機(ji)(ji)重(zhong)要閥門(men)動(dong)(dong)作試(shi)驗(yan)(yan)(yan)(yan)(yan)、負荷(he)變(bian)動(dong)(dong)試(shi)驗(yan)(yan)(yan)(yan)(yan)、功(gong)(gong)(gong)率(lv)分布測(ce)量(liang)，功(gong)(gong)(gong)率(lv)系數測(ce)量(liang)、甩負荷(he)試(shi)驗(yan)(yan)(yan)(yan)(yan)、堆芯(xin)穩態性能試(shi)驗(yan)(yan)(yan)(yan)(yan)、電(dian)(dian)(dian)站性能試(shi)驗(yan)(yan)(yan)(yan)(yan)、熱(re)平衡(heng)試(shi)驗(yan)(yan)(yan)(yan)(yan)等測(ce)試(shi)和實驗(yan)(yan)(yan)(yan)(yan)。在后(hou)(hou)續即(ji)將完成(cheng)的(de)機(ji)(ji)組(zu)100小時(shi)可靠性示范運行(xing)后(hou)(hou)，即(ji)可滿足臨時(shi)驗(yan)(yan)(yan)(yan)(yan)收的(de)必要條件。在此期(qi)間(jian)，為了安全達到臨時(shi)驗(yan)(yan)(yan)(yan)(yan)收的(de)條件，堆芯(xin)熱(re)停(ting)堆3次，冷停(ting)堆1次，計4次小修(xiu)。在中原公司的(de)組(zu)織(zhi)下，各(ge)單(dan)位通力協作，不辭(ci)辛勞(lao)、晝夜搶修(xiu)，各(ge)項缺陷迅(xun)速(su)(su)得到消除(chu)，保證(zheng)了功(gong)(gong)(gong)率(lv)曲線上升的(de)圓滿成(cheng)功(gong)(gong)(gong)。
