RIOHMOND, VIRGINIA 2 3 2 61 January 28, 1977 Mr. Benard C. Rusche Director of Nuclear *Reactor Regulation U. S. Nuclear Regulatory Commission Washington, D. C.

20555 Attention:

Mr. Robert W. Reid, Chief Operating Reactors Branch No. 4

Dear Mr. Rusche:

Docket No. 50-280 License No. DPR-32 We acknowledge receipt of Mr. K. R. Goller's letter, dated January 19, 1977, which forwarded Amendment No. 29 to the license for Unit No. 1 at the Surry Power Station and also the Safety Evaluation which provided the technical basis for the amendment action.

We note a qualification in the Amendment which is inconsistent with the technical conclusions of the Safety Evaluation, which could have an adverse impact on our ability to provide essential power during a critical demand period in our service area.

Accordingly, and for reasons as* stated below, we are requesting an Amendment to Operatin*g License DPR-32 to provide for an additional four (4) day extension beyond ~he time limits imposed by Amendment No. 29.

Details in support of this request are as follows.

On January 19, 1977, the NRC Staff advised Vepco by telephone that as of that date Surry Unit No. 1 was restricted to twenty (20) days of effective full power days of operation (EFPD) pending Vepco submission of and Staff review and approval of responses to two additional technical questions regarding steam generator tube integrity.

The following day we received, via tel'ecopier, a copy of Mr. Goller's le.tter of January 19, 1977, lessenclosures.

We noted that the time limit restriction was stated in that letter as 1120. equivalent power days".

Nevertheless, based on telephone discussions with the Staff we had no reason to assume that we did not have a twenty (20) effective full power day restriction and our unit availability planning proceeded on that basis with a scheduled unit availability time/date 1 imit of 11:00 p.m. February 12~ 1977 for Surry Unit 1.

We recognized that our submittal of the two outstanding reponses on steam generator integrity had to be made sufficiently in advance of ihat date to permit a minimum of a week's review by the staff.

Our planned submittal was, and remains, February 4, 1977, a date which accomodates to the above schedule.

However, when we received Mr. Goller 1s January 19th letter on January 25, 1977, we noted that the operational restriction in Amendment No. 29 was stated in terms of 1120 equivalent days of operation from January 19, 1977...*****

with a primary coolant temperature greater than 350<?F11

• Based on Unit 1 operations since January 19, 1977, this results in an advance of the expiration period to approximately 8:00 p.m. on February 8, 1977.

We wish to assure you that we are doing everything possible to expedite our submittal to the Staff of that technical information which is out-standing; however, we recognize that further questions within the framework of j_()35

-Mr *. Bena rd. C. Rusche 1/28/77 2

the two identified in Appendix A to the Safety Evaluation m_ight also sti 11 be raised by the Staff.

In view of the above and our firm belief that the technical infor-mation and the stated conclusions of our January 14, 1977 *submittal warrant at the very least an authorized twenty (20).effective full power day period of operation, we urgently request a four (4) day (EFPD) extension beyond the limit imposed b*y Amendment No. 29 to our Unit 1 License. *we do this to safeguard the availability of a valuable generating unit during an unprecendented energy demand period on the east cost of the U. S. in general and within the Vepco System in particular, under circumstances where nuclear safety will not be degraded.

We would appreciate your cooperation in this matter.

Very truly yours,

\\.
