Mr. Harold R. Denton, Director Serial No. 479A Office of; Nuclear Reactor Regulation N0/JHL:acm Attn: Mr.' James R.' Miller. Chief Docket No. 50-339 Operating Reactors Branch No. 3 License No. NPF-7 Division of Licensing U. S. Nuclear Regulatory Commission Washington',D. C. 20555 Gentlemen:-

VIRGINIA ELECTRIC AND POWER COMPANY NORTH ANNA POWER STATION UNIT NO. 2 REACTOR VESSEL MATERIAL SURVEILLANCE TEST RESULTS In our letter dated August 16, 1984, Serial No. 479, we indicated that an amendment request would be submitted to the NRC by October, 1984 based on the-evaluation of the first capsule of the reactor vessel surveillance program for North Anna Unit No. 2. This. amendment request would revise the pressure-temperature limits and the operating period for the new limits.

During- the review of the proposed amendment request to the pressure-temperature climits, it- was determined that the effect on the PORV low teraperature protection setpoints to provide adequate over-pressurization

.. protection must be evaluated. To avoid multiple amendment submittals, we propose submitting the revised pressure-temperature limits, with any necessary PORV setpoint changes, by February, 1985. This will allow a combined submittal with the Unit 1 amendment request.

If you have further questions please contact us.

y truly yours,
