The USNRC issued Generic Letter 89-13, ``Service Water Problems Affecting Safety-Related Equipment`` to all nuclear power plant licensees which requires the implementation of a program to ensure that nuclear safety-related heat exchangers are capable of performing their intended functions. The heat exchangers on the standby emergency diesel generator (EDG) skids are covered by this requirement. PECo and SWEC have developed a program of testing and analysis to monitor the level of fouling in the EDG`s at the Limerick and Peach Bottom nuclear power plants in response to the Generic Letter. The development of an EDG heat exchanger test program is significantly more complex than for most other heat exchangers. This is because the process fluid flows are controlled by self-modulating thermostatic valves to maintain proper process temperature setpoints. As a result, under some test conditions the process flows may be reduced to as little as 20% of their design values. Flow changes of this magnitude significantly affect the performance of the coolers and obscure observation of the effects of fouling if not properly addressed. This paper describes the methods developed by PECo and SWEC to address this problem.
