VinorNrA ELECTRIC AN D l' OWE H COM I% NY nicmrown,v:nonnu 20261 October 31, 1979 Mr. Harold R. Denton, Directc- Serial No. 885 Office of Nuclear Reactor Regulation LQA/ESG: sir Attn: Mr. O. D. Parr, Chief Light Water Reactors Branch No. 3 Docket No. 50-339 Division of Project Management U. S. Nuclear Regulatory Commission Washington, DC 20555

Dear Mr. Denton:

In accordance with 10 CFR 50.55(b), the Virginia Electric and Power Company hereby requests that Construction Permit No. CPPR-78 be extended by revising the latest completion date for construction of North Anna Unit No. 2 to December 1, 1980-When we last requested extension of the construction permit (Sep tember 26, 1978), we noted that our official fuel load date was December 22, 1978, but that we considered April 1,1979 to be more realistic. Accordingly, we requested a construction permit expiration date of December 1,1979 to allow for any unforeseen factors which could further delay construction completion.

Since that time, various f actors have resulted in a need to further ex-tend the constructic, normit. Several construction or engineering related items delayed the crmpletion of construction, as outlined in Attachment 1 In addition, licensing delays as a result of the Three Mile Island accident have prevented issuance of an operating license by the date originally anti-cipated. These delays have included the NRC Staff's three month noratoriua on licensing, the extensive reviews conducted by the NRC Lessons Learned and Bulletins and Orders Task Forces, and the Commission decision to review all license applications after their approval by the Staff.

Based on our estimates of time required for completion of construction items required for fuel loading, operator testing and relicensing now required by the Staff, and reviews necessary for Staff approval of an Operating License, we have established December 2,1979 as the new Load Fuel date. However, since the schedule impacts of the requirement for Commission approval of our applica-tion, as well as the various investigations of the Three FEle Island accident now underway, are uncertain, the construction permit should be extended to allow for fur ther dela;3. We, therefore, request that Construction Pernit CPPR-78 be extended to December 1,1980. Since this request only involves activities already reviewed and approved by the Commission, and construction of the unit is essentially complete, no significant hazard or change in environmental impact would result from its approval.

ATTACHMENT 1 NORTH ANNA UNIT NO. 2 MAJOR PROJECT DELAY ITEMS CONTRIBUTING TO REVISION OF FUEL LOAD DATE FROM 12-22-78 TO 12-02-79

1. Additional or modified pipe hanger designs and final stress analysis for various Category 1 piping systems were a major factor in delaying con-struction completion. These additions / changes were required as a result of engineering studies or reviews including Higher Service Water and Coa-ponent Cooling Water Temperatures, Higher Service Water Flows to Charging Pump Coolern, Nozzle Loads and Equipment Support Reactions,Scismic Re-analy-sis of Main Steam Valve House, Annulus Rack Seismic Review.

Delay: 18 weeks

2. Additional High Energy Whip Restraints (SI piping in containment)

Delay: 6 weeks

3. Resolution of Overheating of Recirculation Spray Pump Motors Delay: 8 weeks

4. Reserve Station Service Transformer cable feed modifications Delay: 13 weeks NOTE: The above delay items were overlapping, and represent an allocated portion of the total delay. If these had occurred individually in series, the sched-ule impact would have been more severe.
