Mr. B. H. Crier September 22, 1980 BVPS: JAW:979 Page 2 No cause is known at present for the loss of cooling water. The consequences of this event were minimized due to the availability of the temporary fire pump, the short period of time that the diesel fire pump was inoperative after the motor-driven pump failure, and the motor driven pump could have been run for a short time if an emergency arose.
Very truly ycurs,
