【摘  要】针对某核电厂RRI/SEC板式换热器旁路改造后无法按照传热系数来进行换热器性能评价的现状，论文给出了一种使用热负荷来评价换热器性能的方法，在曲线上方的试验数据说明换热器性能合格，可以实现冬季运行时换热器试验不需要进行运行模式切换。

【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.
