Dear Mr. Danna:

In Reference (a), the NRC provided the public the opportunity to comment on the proposeddetermination that the license amendment request involves no significant hazards consideration. Crediting the functionality of the service water system during the period when the cooling tower in unavailable while in Modes 5 and 6 in the current refueling outage is appropriate. The preventivemaintenance on the cooling tower is an important activity to maintain the long term health of thecooling tower. Performing this activity during a refueling outage is appropriate as the risk to the public health and safety is extremely low and the administrative controls to return the cooling towerto operation in the unlikely event of the loss of the ocean supplied service water system provide thenecessary defense in depth.

I have reviewed the response to the three questions provided by the licensee in Reference (a) andconcur that the proposed change does not involve a significant reduction in the margin of safety.

I encourage the NRC to issue the exigent amendment to the Operating License.

Michael Ossing
