摘要
改进型三环路压水堆核电机组辅助蒸汽供应系统在某些情况下偶尔会出现压力不稳定的情况。为了确定短时间压力波动是否影响常规岛用户的正常运行,文章对下游用户的运行特点和运行参数进行分析。通过计算比较用户与辅助蒸汽的换热量,理论验证了当常规岛部分辅助蒸汽压力下降到最小值0.45MPa时,也能够满足下游长期用户的使用需求。
In order to determine whether the short time pressure fluctuation will affect the normal operation of regular island users,the operation characteristics and parameters of downstream users are analyzed.By calculating and comparing the heat exchange between the user and the auxiliary steam,the theory proves that when the auxiliary steam pressure of the regular island part drops to the minimum value of 0.45mpa,it can also meet the demand of long-term downstream users.
