Subject:
Vendor Interface for Safety-Related Components - Generic Letter No. 90-03 Gentlemen:
i Reference (b) requested Licensees to review their present' vendor interface programs and modify their programs as necessary to assure the program elements-set out in the generic letter are met.
Licensees undertaking the. actions were requested to confirm that they have examined their vendor interface programs, that their programs either-already include both of the elements set out'in the generic letter or that the elements have.been scheduled for implementation.
Maine Yankee's vendor interface program was initially addressed in response to Generic Letter 83-28 (Reference (c)) by Reference-(d). Additional'information on our program was provided to the staff by References (e) and:(f).
On May 12-16, 1986, Region I conducted a special inspection of Maine Yankee on various -
j activities including vendor interface.
Subsequently by Reference (h), the NRC issued its Safety Evaluation of our vendor interface program and= accepted our response to the vendor interface portion of Generic Letter 83-28. The last paragraph of the Safety Evaluation is quoted:
" Based on the licensee's commitment.to fully implement the NUTAC/VETIP guidance, the actions described in their procedure for vendor interface, and the conclusions and findings of-the referenced staf.f inspection, the staff concludes that the licensee's actions are consistent with the NRC position for Action 2.2.2 of Generic Letter 83-28 and, therefore, acceptable."

In that Maine Yankee already has an acceptable vendor interface program, Reference (b) does not constitute a relaxation of requirements for Maine Yankee.
Pather, the requirement for a vendor interface program for non-NSSS vendors of key safety-related components represents an expansion to our existing program.
Nanetheless, we recognize the importance of having current, up-to-date technical information to operate and maintain the plant and therefore we support the intent of this expanded vendor interface program.
Thus, in response to Generic Letter 90-03, Maine Yankee has examined its vendor interface program against both of the elements set out in the generic letter. -The NRC vendor interface program elements and Maine Yankee's response to each element are as. follows:
NRC Element (a):
A program with the NSSS vendor as described in the VETIP, which covers all the safety-related components within the NSSS scope of supply.
This program should include provisions for assuring receipt by the licensee / applicant of all technical information provided by the NSSS vendor.
Maine Yankee Response (a):
Combustion Engineering (CE) (NSSS Vendor) develops Technical Bulletins which are sent by CE requesting a signed form be returned to CE acknowledging receipt.
4 If they don't receive an acknowledgement form, they follow-up to ensure receipt.
At Maine Yankee, these Technical Bulletins are entered into our Operational Assessment System (0AS) for internal resolution and action as appropriate.
Each of the CE Technical Bulletins received in the past year and the associated 0 ass were reviewed to verify that the recommendations in the bulletins received the-proper Maine Yankee review and action. No unsatisfactory conditions were noted.
CE was contacted to determine if those components listed on the CE Scope of Supply were included within their Technical Bulletin program.
In response, CE indicated that CE did not have any responsibilities to provide any vendor information, that the Technical Bulletin program was entirely voluntarily on their part, and there are not any requirements as to what is included within that program. Although-CE provides no commitment with respect to their Technical Bulletin program, it generally is considered responsive to providing technical information on those safety-related components in the Scope of Supply, it does assure receipt and no further action is considered necessary.
NRC Element (b):
'l A program of periodic contact with the vendors of other key safety-related -
components not included in Element (a) above.

MaincYankee UNITED STATES NUCLEAR REGULATORY COMMISSION MN-90-97 Attention: Document Control Desk Page 3 Maine Yankee Response (b):
Maine Yankee, using the Maine Yankee (PRA-developed) equipment importance ranking, identified the major components of equipment with safety significance.
These were identified independent of whether the component is in the CE Scope:of Supply. This ensures that those components in the CE Scope of Supply for which CE is not the OEM are properly addressed. These components were then further identified as to Model No., Serial No. and vendor. This.resulted in a PRA-based-listing of the key safety related component vendors that potentially should be included in the vendor interface program.
The next step was to determine whether each component vendor periodically has 0&M information available to send to Maine Yankee for our component. There were 165 identified components and the initial contact process with the vendors to determine if they have update information available is ongoing.
It is expected that for many vendors, update information for the model installed at Maine Yankee will not be available. Those that do provide update information will constitute the vendors that should be added to the i
program.
(
The expanded PRA-based vendor interface program based on those vendors who do provide update information for key safety-related components including a documented telephone contact procedure will be incorporated into Maine Yankee Procedure 0-06-7 and effective by January 1, 1991.
Should you have any questions on this issue, please contact us.
Very truly yours,
