Inservice Inspection (ISI) activities 14.
Data Review and Evaluation The inspector reviewed nondestructive examination (NDE) data included within the below' listed ASME categories per tables IWB-2500 and IWC-2520.
The review was conducted to ascertain completeness and accuracy in accordance with the ASME Code and regulatory requirements; the ASME categories. included:
B-A B-K-1 B-B B-K-2
.B-C B-M B-D B-0
~B-E-C-C B-F C-E-1 B-G-1 C-E-2 B-G-2 C-F B-H C-G
B-5 Also the inspector reviewed the NDE data for the welds included in sample number 3 of the licensee's augmented examination program for the isolation condenser system and reviewed repair records for weld NE-1-15.
This weld was selected because it had been rejected and replaced as a result of the augmented program. The repair weld trave-1er and associated quality records were reviewed for completeness and accuracy.

-3-For all of the above, the methods, technique and extent of examinations were found to comply _with the 1983 ISI program and its applicable procedures.
However, this review revealed that several welds on the reactor vessel bottom head were not listed within the licensee's ISI Program (i.e. welds 3-562-A thru F).
Further-investigation revealed that relief from the Code-required volumetric examination for these welds had been2 granted by the NRC in a letter dated June 28, 1983, with the
' understanding that an alternative visual examination be performed
"
during vessel hydrostatic tests in accordance with station procedure
'602.4.007 Rev. 3.
Following discussions with the inspector, the licensee agreed to-list these visual examination requirements within the ISI program.
Results: No violations were identified.
B '.
Procedure Review The inspector reviewed the following NDE procedures for technical adequacy and content:
a Liquid Penetrant Examination Procedure MTIS-007 Rev 3 Magnetic Particle Examination Procedure MTIS-004 Rev 3 Ultrasonic Examination Procedure MTIS-013 Rev 3 Results: No violations were identified.
C.
Document Review The inspector reviewed the following documents in order to establish the basis for judging the acceptability of the licensee's ISI program:
1983 Inservice Inspection Final Report Schedule for the April 1986 Outage Relief Request Letters dated June 28, 1983 and May 22, 1985 GPUN Technical Data Reports 571 and 657
- cs GPUN Letter dated June 5,1981

Subject: ASME Year and Addenda for ISI.
i GPUN Augmented Inspection Procedure SP-1302-23-006 This review revealed that the following fifteen overlaid safe end welds have not been surface or volumetrically examined due to as-welded surface conditions:
10 recirculation system welds 2 isolation condenser supply line welds 2 core spray line welds I control rod drive hydraulic system return line weld

However the inspector noted that GPUN has committed to develop an-adequate examination technique for these bimetallic safe end nozzle welds, in order to satisfy.the requirements of Generic Letter 84-11 by April 1986 outage.
Results: No violations were identified.

Equipment Calibration
,.
The inspector verified the calibration records for the below listed equipment used for ISI examinations during the 1983 outage:
Ultrasonic
Kaulkramer-- Branson USL-38 Serial Number 211050 USL-37 Serial ~ Number 211581 Magnaflux P5710 Serial Number 821646 Sonic Mark 1 FTS-1 Serial Number 780839 Magnetic Particle Magnaflux Yoke Serial Number 6034-11 Magnaflux Yoke Serial Number 6034-10 Magnaflux Yoke Serial Number 6035-1 Results: No violations were identified.
