Re: Final copy Farley AITNRC slides.ppt The updates you suggest look good to me. Thanks. -David>>> Stephen Alexander 09/19/2007 10:00 AM >>>Again, in my view, the short version language will be a bit confusing to laymen. Attached is a suggested version -not longer -not to worry -but simpler language.

It reads as follows: On September 4, 2007 In support of planned maintenance on the 1 B component cooling water (CCW) pump, the licensee needed to start another pump.The Cutler-Hammer breaker for the IC CCW pump failed to close when the licensee attempted to start the pump.On September 5, 2007 Since the 1 B pump was out of service for maintenance and the 1 C breaker had failed to close, the licensee needed to start the remaining CCW pump, the 1A. Upon attempting to start the 1A CCW pump, its Allis-Chalmers breaker failed to close, but, as it turned out, for a un-related reason.>>> Karen Cotton 09/19/2007 7:36 AM >>>Thanks, Karen CC: Mike Franovich; Robert Martin S"13
