The following subjects were discussed:
A.
The inspector stated t' tat the program does not define responsibilities for the analysis and rpproval for the testing results and for the preparation of the fin-1 report.
This was acknowledged with the cocaitment that these responsibilities would be defined.
Ihis item is unresolved. (retails, Paragraph 3)
B.
The inspector stated that the new revised procedure NIP 001 on site and used in testing programs did not thew evidence of review and approval by G.P.U. as required.
The CAI representative stated that the procedure had been reviewed and approved and that the signed copy was located in the GAI office in Reading, Pennsylvania.
The inspector was informed that the approved procedure would be available on site by December 6,1973. This item is unresolved.
(Details, Paragraph 4)
C.
The inspector stated that the Inservice Inspection plan notes in Attachment "C" that the G.P.U. Representative has control
of inspection activities. Evidence was not available to show any surveillance, inspections or audits performed that would show licensee activities in the performance of the testing.
The GPU
.
.
representative stated that inspection reports would be issued and (_
audits would be performed on the test data.
This is an open item. (Details, Paragraph 5)
D.
Four of the main steam welds were ultrasonically tested in response to the Atomic Energy Commission criteria for identification of postulated break locations in high energy piping systems. One of the four velds tested required weld repair.
Further testing of other welds is not planned.
This is an unresolved item. (Decails,

Persons Contacted G. Josephs - Gilbert Associate Inc. - ISI Program Manager C. James - Con Am - Ultrasonic Test Supervisor 2.
General This trip was made to the site for the purpose of inspecting the program for base line and inservice inspection.
3.
The program has attachments which list and define the re'sponsibilities of each of the groups which are involved with the base-line inspection of Metropolitan Edison: General Public Utilities Service Corporation, Gilbert Associates, Inc. and Con Am.
These attachments are very definitive in the outline of program management, tes ting procedures,
interface relations between groups, retention of records, etc.
However, the responsibility for the final review, approval of
,
test reports and the compilation of the final report was not defined.
,
4.
The review of the testing precedures revealed one of the procedures NIP 001 Con Am had been revised on the site and reissued.
The
,
revised edition was used to perform the U.T. testing.
Ihe revised procedure did not show that the required approval had been made by G.P.U.
The inspector was informed that the approval had been made by G.P.U. and that the signed copy of the procedure was located at the G.A.I. office in Reading, Pennsylvania and would be
,s (_,
issued to the site by December 6,1973.
5.
Attachment "C" of the inservice inspection plan stated that the GPU/QA site representative has control of inspection activities.
If in his judgement inspections are not satisfactory he may stop work until conflicts are satisfactorily resolved.
!
A review was made to determine the extent of GPU/QA involvement and activities in the performance of the actual testing performed or a surveillance activity to determine the compliance of the testing to the requirements of the approved procedures.
There was no documentation available to show any GPU/QA activity such as surveillance inspections, or auditing or involvement in this aspect of the testing program.

.
The licensee's response to the AEC request, " General Information Required for Consideratien of Effects of Piping System Break Outside Containment" of December 15, 1972 and supplemental letter dated June 1,1973 stated that a design review had been performed.
The design review identified the most highly stressed joints in these lines to be in the main steam lines. The licensee elected to (w

-4-O ultrasonically examine the 4 most highly stressed welds in the t
-
main steam line during the pre-operational base line inspection and to include these welds in future inservice inspections.
The inspector found that the licensee had ultrasonically examined main steam line welds MS50A-1, MS50B-1, MSS 1 and MS50-12. It was found that an unacceptable defect had been discovered in MS-50-12 on August 1, 1973.
This was documented in DR-1030 which identified MS-50-12 to be a Grinnell Company Shop Weld; the defect was
-
identified as 7/8 inches long and 3/8 inches below the finished surface of the weld. The weld defect was ground out and repaired
,
in accordance with UE&C Weld Procedures Nos. 1 and 20 and ultra-sonically reinspected and found to be acceptable. DR 1030 was
,
closed on September 6, 1973.
The inspector stated he could not find any commitment in the Technical Specifications to examine these welds in the inservice inspection.
The licensee stated that the Technical Specification would be revised to include the requirements for continuing
,
examination of the four velds. This matter is considered unresolved i
pending '.-erification of the inclusion of the 4 main steam line welds in the inservice inspection program.
