快堆蒸汽发生器的传热管在沸腾传热恶化区会产生温生脉动,温度脉动可能加速换热管的腐蚀,也会导致管子上的交变热应力的出现,从而影响蒸汽发生器的使用寿命,因此本文对沸腾传热恶化区蒸汽发生器换热管的温度脉动特性进行了研究。重点讨论了水/汽侧压力、质量流速、钠侧 The heat transfer tube of the fast reactor steam generator will produce thermophilic pulsation in the deterioration area of ​​boiling heat transfer. The temperature pulsation may accelerate the corrosion of the heat exchange tube and also lead to the occurrence of alternating thermal stress on the tube, thus affecting the steam generator Therefore, this paper studies the temperature pulsation characteristics of the heat transfer tube of steam generator in the deterioration area of ​​boiling heat transfer. Focus on the water / steam side pressure, mass flow rate, sodium side
