Dear Chaiman Hendrie:
I understand that the Nuclear Regulatory Commission has authorized the replacement of defective steam generators at Virginia Electric and Pcwer Company's Surry Nuclear Power Plant.
Further, I understand that this is the first nuclear plant repair of its type to be performed. Turefore, I would appreciate receiving infomation on the nature of the problem and the repair procedure involved.
Specifically, it would be helpful if you could supply answers to the following questions:
1.
How widespread is the problem of steam generator tube denting, and what are the safety implications involved?
2 How has NRC dealt with the problem in the past, and what future activities (and levels of effort) are planned to resolve this safety issue?
3.
Please describe the NRC environmental and safety review procedure which led to the authorization of this repair work. Were these reviews subject to public hearings or comment?
4.
Please describe the steam generator replacement procedure which is being employed.
5.
What environmental and safety precautions is NRC requiring prior to and during replacement activities? To what extent will NRC review and monitor this effort?
6.
What will be done with the defective steam generator parts?
hb t are the associated environmental and safety risks involved in the s orage and/or disposal of these parts?

Joseph M. Hendrie Page 2 7.
Will the steam generator supplier, Westinghouse, pay for this damage repair or are the costs to be passed on to the VEPCO consumer?
8.
Are other nuclear power plants scheduled to undergo similar replacement repairs?
If so, which ones, and when?
Mr. Chainnan, this infonnation will be useful to the Subcomittee on Nuclear Regulation in its ongoing oversight of commercial nuclear regulatory activities. As the replacement procedures at Surry have already recently commenced, your timely response to these questions would be greatly appreciated.
Sincerely, M
Gary rt Chai
