Dear Mr. Denton:

As a result of R. C. Arnold's discussions with you on April 22, 1982, regarding the TMI Steam Generator Program, he asked me to forward to you the charter and the r amposition of the Independent Third Party Review Group which we hese established. These documents are attached; the group has had its initial meeting on April 23, 1982.

Very t uly yours, i

ATTACHMENT 1 THIRD PARTY REVIEW OF TMI-1 OTSG REPAIR PROGRAM CHARTER I. PURPOSE It is the intended purpose of this " Third Party Review" (TPR) to provide o timely, independent, objective, safety evaluation of all activities defined in this charter for conformance to: 1) the NRC rules &

regulations governing the operation of TMI-1; and 2) the adequacy of the cteam generator repair program that will allow safe operation of the nuclear unit.

II. SCOPE The scope of this review is generally limited to activities associated with the identification of failure mechanisms and repairs of the TMI-l Once Through Steam Generators (OTSC's). The specific task areas to be reviewed are described in more detail in Section IV of this charter. It is the intent of CPUN Managemnt to fully develop and implement repairs to the THI-l OTSG's within the provisions of 10CFR50.59. It is expected that the TPR ill promptly notify GPUN Management of any circumstance tiot already identified by CPUN, that fails to meet these standards.

III. MEMBERSHIP The membership of the TPR body shall include individuals with expertise in the following specialty areas: -

A. Steam Cencrator Design and Performance - 1 member B. Chemistry - 1 member C. Materials - I member D. Stress Analysis - 1 member E. Safety Analysis - 1 member F. Plant Operations - 1 member C. Non-Destructive Examination - 1 member The TPR shall have a CPUN individual assigned as Secretary for the review. He will be the general interface for the TPR membership and CPUN. A Chairman will be elected and report the results of the review directly to the Vice President - Technical Functions in this assignment.

The Secretary will arrange for all review material, meetings and recordkeeping for the team. Any specific information requests within the scope of the TPR should be to the Secretary. The Secretary will be o non-voting member in any matters of the TPR seeking concensus cpinions.

i

O o .

r Members of the TPR will either be from outside the GPUN organization or from the portion of GPUN not responsible for the steam generator repair or TMI-l operat ions .

IV. SPECIFIC REVIEW AREAS A. Failure Analysis Program This program is intended to identify the cause of tube cracking and means to arrest it.

B. Eddy Current Examination Program This program is to develop and implement an eddy current examination method to identify the extent of the tube cracking problem.

C. OTSC Performance Evaluation It is the object of this effort to evaluate the impac t of the repair procedures on the performance of the steam generators, especially in the area of safety analysis.

D. Repair Criteria This program is intended to provide guidance concerning the type of repair to be done on the damaged tubes. ,

E. OTSG Repair Program s

This progran covers the actual repair of the steam generators.

V.  !!EETING FREQUENCY The TPR shall initially meet to receive a presentation by GPUN and its '

consultants on the current status and direction of the OTSG Repair Program. At that meeting, they will be presented with initial reference material that will enable them to assess products then available.

A second meeting will be scheduled by GPUN to make a final presentation j to the TPR prior to initiation of the final production repairs.

l Other meetings may be held at the discretion of the TPR.

VI. RECORDS The Secretary shall maintain records of all meetings of the TPR. The Secretary shall also maintain a record of all documents reviewed by the membership. Portions of the material may be proprietary in nature.

Appropriate arrangements shall be made to protect proprietary information when it is used.

8 Transcripts may be taken of the final review meeting and used as part of the documentation package a'isilable to the NRC in support of the OTSC Repair Program.

A final report will be prepared by the review team which summarizes its findings and conclusions regarding the safety adequacy of the repair program. The report should make an explicit finding that the approach proposed by CPUN is adequate if that is the conclusion of the review.
