STATE CORPORATION COMMISSION DIVISION OF ENERGY REGULATION Mr. Bart c. Buckley Senior Proj~ct-Manager October 12, 1989 Division of Reactor Projects II-2 Office of Nuclear Reactor Regulation Nuclear Regulatory Commission Washington, D.C. 20555
Dear Mr. Buckley:
BOX 1197 RICHMOND, VIRGINIA 23209 Thank you for your prompt response to our earlier questions regarding the September-14, 19 88 Surry Unit 1 outage.
Our investigation of this outage is continuing.
As you are aware, the NRC Inspection Report Nos. 50-280/89-16 and 50-281/89-16 was issued on September 22, 1989.
The last paragraph on page 24 of this report reads:
Early in the assessment
- period, the engineering organization had not demonstrated an adequate self-assessment capability.
A specific example was the lack of administrative control for the backlog of potential problem reports which were generated in the corporate offices.
Incorrect assessment of safety significance of outstanding issues was identified as a problem area.
This condition became obvious when significant safety issues (i.e.,
emergency diesel generator sequencing problems and control room envelope air conditioning/ventilation problems) were first addressed in the licensee's corrective action program approximately two years after they were identified.
For clarification purposes, please elaborate on that portion of the above paragraph that I have underlined.
Specifically, please respond to the following questions.
In the NRC's opinion, did Virginia Power perform a timely study of the IEIN 85-91 as it related to the Surry Power Plant?

Did Virginia Power make a correct and timely assessment of the emergency diesel generator sequencing problems?
Was Virginia Power's corrective action ( Surry Unit 1 shutdown) timely?
Once again, your cooperation is very much appreciated.
Your timely response will be quite useful in completing our investigation.
Should you have any questions, pl ease contact Mr. Massoud Tahamtani at (804) 786-4314.
WTL/mv Very truly yours, wt (
