【摘要】：中國實(shí)驗(yàn)快堆(CEFR)以鈉作為冷卻劑。事故余熱排放系統(tǒng)是CEFR快堆的專設(shè)安全設(shè)施,在反應(yīng)堆出現(xiàn)地震、系統(tǒng)供電全部中斷、全部蒸汽發(fā)生器給水中斷的事故工況時,將堆芯余熱通過空氣冷卻器非能動地排放到最終熱阱。CEFR事故余熱排出系統(tǒng)設(shè)計(jì)溫度為550℃,運(yùn)行溫度最高為516℃,全部為雙層管道,管道內(nèi)運(yùn)行介質(zhì)為高溫的液態(tài)金屬鈉。通過對事故余熱排放系統(tǒng)進(jìn)行熱應(yīng)變測量和數(shù)據(jù)分析,掌握系統(tǒng)管道的應(yīng)力應(yīng)變情況和監(jiān)測系統(tǒng)運(yùn)行狀態(tài)的應(yīng)力變化。
[Abstract]:China Experimental Fast reactor (Cefr) uses sodium as the coolant. The accident waste heat discharge system is a special safety facility for the CEFR fast reactor. In the case of an earthquake in the reactor, the power supply of the system is completely interrupted, and the supply water of all steam generators is interrupted. The reactor core waste heat is discharged into the final heat trap. CEFR accident residual heat discharge system inactively through the air cooler. The design temperature is 550 鈩，
