VIRGINIA ELECTRIC AND POWER COMPANY RicHmIMOND, VIRGINIA 23261 Re: 10 CFR 2.202 February 28, 2003 Secretary, Office of the Secretary of the Commission Serial No.:
03-143 U.S. Nuclear Regulatory Commission NL&OS/ETS ATTN: Rulemakings and Adjudications Staff Docket Nos.: 50-338 Washington, D.C. 20555-0001 50-339 License Nos.:NPF-4 NPF-7 Gentlemen:
VIRGINIA ELECTRIC AND POWER COMPANY NORTH ANNA POWER STATION UNITS 1 AND 2 ANSWER TO ORDER FOR INTERIM INSPECTION REQUIREMENTS FOR REACTOR PRESSURE VESSEL HEADS AT PRESSURIZED WATER REACTORS DATED FEBRUARY 11, 2003 On February 11, 2003, the Nuclear Regulatory Commission (NRC) issued an Order for Interim Inspection Requirements for Reactor Pressure Vessel Heads at Pressurized Water Reactors licensees.
The Order requires specific inspection of the reactor pressure vessel (RPV) head and associated penetration nozzles at pressurized water reactors (PWRs).
The Commission stated that the actions in the Order are interim measures, necessary to ensure that licensees implement and maintain appropriate measures to inspect and, as necessary, repair RPV heads and associated penetration nozzles. The Order required that licensees immediately start implementation of the requirements of the Order and respond to specific actions within twenty (20) days of the date of the Order.
In accordance with Section V of the Order and 10 CFR 2.202, Virginia Electric and Power Company (Dominion) hereby submits its answer to the Order.
Dominion consents to the Order as described in Section IV and does not request a hearing.
The North Anna Units 1 and 2 RPV replacement head penetration nozzles have thermal sleeves installed that could preclude 100 percent inspection coverage of the penetration nozzle base material in the area of the J-groove weld as required by Section IV.C(3)(b) of the Order. The thermal sleeves for the replacement RPV heads were designed and installed to reduce the possible interferences associated with ultrasonic or eddy current examination of the inside diameter of the penetrations; however, until the first inspections required by the Order are performed, the exact limitation on coverage cannot be established.
If 100 percent coverage of the area of interest cannot be
obtained during inspection of the penetration nozzles, Dominion will seek relaxation from the inspection requirements in Section IV.C(3)(b) of the Order at that time.
If you have any questions, please contact Mr. Thomas Shaub at (804) 273-2763.
