【摘? 要】針對某核電廠RRI/SEC板式換熱器旁路改造后無法按照傳熱系數(shù)來進(jìn)行換熱器性能評價的現(xiàn)狀，論文給出了一種使用熱負(fù)荷來評價換熱器性能的方法，在曲線上方的試驗(yàn)數(shù)據(jù)說明換熱器性能合格，可以實(shí)現(xiàn)冬季運(yùn)行時換熱器試驗(yàn)不需要進(jìn)行運(yùn)行模式切換。

【Abstract】The performance evaluation of RRI/SEC plate heat exchanger in a nuclear power plant can not be evaluated according to the heat transfer coefficient after the bypass modification， aiming at this situation， the paper puts forward a method to evaluate the performance of heat exchanger by using heat load， the test data above the curve shows that the performance of heat exchanger is qualified， which can realize the heat exchanger test in winter without switching operation mode.
