Abstract
The four methods are used to simulate component cooling water plate heat exchanger in Fuqing unit 1&2 nuclear power plant, they are criterion number heat exchange formula, HTRI (Heat Transfer Research Institute) heat transfer factor empirical formula, Matin heat transfer factor empirical formula and A.Muley heat transfer factor empirical formula. The minimum difference of heat exchange area is calculated by using criterion number heat exchange formula compard with the operation data in Fuqing unit 1&2 nuclear power plant . So this method is used to analyse component cooling water plate heat exchanger in HPR1000 nuclear power plant, the heat exchanger supplied by factory comply with the engineering request,such as both in normal operation condition and in LOCA condition, the heat exchanger should remove enough heat to sea water. The problem in nuclear power plant that component cooling water subcool caused by sea water temperature subcool is a general issue for low-temperature site in winter. It supplied three measures to settle the problem, using the above method, the treatment of this problem for HPR1000 is chosed, and the calculation results of heat exchanger is given, the issues of plant unsafety operation and unplanned outage caused by component cooling water subcool is resolved.
