VIRGINIA ELECTRIC AND POWER COMPANY NORTH ANNA POWER STATION UNITS NO. 1 AND 2 REACTOR VESSEL MATERIALS SURVEILLANCE PROGRAM On April 30, 1985, Virginia Electric and Power Company requested amendments in the form of changes to the Technical Specifications, to Operating Licenses NPF-4 and NPF-7 for North Anna Units No. 1 and 2, respectively.
The proposed changes involved updating the pressure-temperature limit curves to be applied during heatup and cooldown, in accordance with 10 CFR 50 Appendices G and H.
Also presented in our April 30 submittal were the evaluation reports associated with removal of the first capsules for the Reactor Vessel Materials Surveillance Program.
On Tuesday, September 24, 1985, in a Telephone Conference with the NRC staff regarding our submittal, Mr. Barry Elliot of the h7C requested that we supply the capsule withdrawal schedule associated with the Vessel Materials Surveillance Program, or commit to a date for supplying a program which would, as far as practicable, be in compliance with the latest revision of 10 CFR 50 Appendix H.
In a subsequent telephone call on October 1, 1985, we committed to supplying the details of an updated surveillance program for North Anna Units 1 and 2 by April 15, 1986. The purpose of this letter is to provide written confirmation of that verbal commitment.
As we discussed during our September 24 conference, we are currently performing a thorough programmatic review of our Vessel Materials Surveillance Programs for both our North Anna units in light of the most recent versions of 10 CFR 50 Appendices G and H, American Society for 8510290253 851021 DR ADOCK 050C0338 goal m
