UNITED STATES
NUCLEAR REGULATORY COMMISSION
WASHINGTON, D.C. 20555

Docket Nos. 50-3
and 50-247

Dear Mr. Cahill:
SUBJECT: NRC STAFF REVIEW OF RESPONSES TO I&E BULLETINS 79-06 AND 79-06A
We have completed a preliminary review of the licensee responses to I&E
Bulletins 79-06, 79-06A, and amendment 1 to 79-06A. The purpose of this
letter is to advise you of the potential problem areas, and to identify
related concerns which we believe require your further examination.
We have scheduled a meeting with owners of all operating plants having
Westinghouse designed nuclear supply systems. This meeting will be held on
May 30, 1979, in rooms P-110/114 at our Phillips Building office in
Bethesda, Maryland. You are expected to attend the meeting and be prepared
to discuss those matters identified below along with a schedule and
procedure for providing the information needed by NRC to complete the review
of these issues.
(1) Our preliminary review of the Bulletin responses indicates that a
number of the Bulletin items are not yet satisfactorily resolved.
Enclosure 1 provides a summary of our current assessment of the
responses to the Bulletins issued on Westinghouse plants.
(2) In certain instances, licensee responses differ, without apparent
justification, from the Westinghouse recommendations for individual
Bulletin items. We expect to resolve each such difference, as well as
licensee exceptions to specific Bulletin responses, prior to our
approval of the Bulletin responses. A copy of the Westinghouse
recommendations is provided as Enclosure 2.
(3) The Westinghouse advice is prescriptive on resetting of the high
pressure injection system and incomplete as to the need for keeping the
reactor coolant pumps running.

(4) We are finalizing a generic report on TMI-2 matters related to
Westinghouse operating plants. Although this report is not yet
complete, among other things, we expect that it will recommend further
analyses of transients and small reactor coolant system breaks, the
development of appropriate written procedure guidance to operators in
the use of these new procedures.
(5) In certain instances, licensees are using fuel and relying on safety
analyses, which were not provided by Westinghouse. As a result, it is
not clear to us what the respective roles of the licensees,
Westinghouse, the fuel suppliers, and/or other parties should be in
implementing those requirements described in item (4) above. We need a
clear and concise definition of their respective roles in these cases.
(6) The Advisory Committee on Reactor Safeguards (ACRS) has issued five
letters to the Commission as a result of their examination of the TMI-
2 accident. We need a clear and concise position from all licensees
with respect to each of the recommendations contained in these letters.
A summary of the ACRS recommendations is provided as Enclosure 3.
(7) Individual licensees have indicated an interest in meeting directly
with the staff regarding the Bulletin items for their facilities.
Experience to date has demonstrated that the staff does not have time
to meet individually with each licensee to resolve these items.
It is clear that there are a significant number of technical issues yet to
be resolved for a large number of Westinghouse operating plants. There are
limited resources available within the NRC staff to perform the necessary
work. This situation is exacerbated by the need to conduct similar and
concurrent activities with those owners of B&W, C-E, and GE designed
operating plants. At the same time, there is a need to resolve these matters
promptly.
To resolve the issues described above in a prompt and expeditious manner, we
believe there is a compelling need to establish an owner's group for
Westinghouse operating plants. We expect that such a group would be needed
for the remainder of calendar year 1979. Owner's groups have worked
effectively in the past in minimizing staff and industry resource
requirements to resolve other generic problems. We strongly urge you meet
with other owners of Westinghouse operating plants to consider the formation
of such a group prior to our meeting May 30. This will be one of the
principal agenda items at that meeting.
.

Please note that investigation of a number of areas related to the TMI-2
accident, including the long-term ACRS recommendations and long-term action
items from NUREG-0560, will be specifically included as part of the future
"Lessons Learned" staff activity. You can expect additional correspondence
in the future on these items.
If you require any clarification for the matters discussed in this letter
please contact Patrick D. O'Reilly, the staff's assigned project manager for
these activities on Westinghouse plants. Mr. O'Reilly may be reached on
(301) 492-7745.
Sincerely,
A. Schwencer, Chief
Operating Reactor Branch #1
