SUBJECT:

REQUEST FOR SUPPLEMENTAL INFORMATION - PALO VERDE UNIT 3, FOR RCS PRESSURE-TEMPERATURE LIMITS DURING HEATUP AND COOLDOWN Submittal of the Unit 3 Technical Specifications is expected in the near future.

To facilitate the staff's review of the TS concerning RCS Pressure-Temperature limits during heatup and cooldown some supplemental information will be required.

The specific information needed by the staff to complete the evaluation is identified in the attached enclosure.

We ask that you provide the requested information by December 31, 1986.

If you have any questions regarding this letter please contact Michael Davis at (301)-492-8897.

Sincerely,
