Inservice Inspection (ISI) Activities a.
ISI Program The ISI program was developed by a testing contractor (Combustion Engineering (CE)) and is based on the ASME B&PV Code,Section XI, 1974 Edition including the 1975 Summer Addenda.
The inspector's audit included the following documents to determine compliance with the aforementioned Code requirements.

ISI Procedure Review j
The inspector audited selected implementing nondestructive examination (NDE) procedures for technical adequacy and compliance with the applic-l able Code requirements.

Procedures audited included:
00000-ISI-029, Revision 2, " Generic Manual Ultrasonic Examination
--
Procedure."
--
6272-ISI-013, Revision 1, " Ultrasonic Examination for Pressurizer Vessel to Nozzle Welds."
6272-ISI-015, Revision 0, " Ultrasonic Examination Procedures for
--
Steam Generator Bottom Head Welds."
6272-ISI-020, Revision 1, " Ultrasonic Examination Procedures for
--
Primary Pipe System."
The inspector considered the above procedures with regard to criteria delineated in 10 CFR 50.55a(g) and requirements of Section XI of the ASME B&PV Code.
This included, but was not limited to, the parameters described below.
c.
Ultrasonic Examination, Manual Contact Technique The type of apparatus, including frequency range, is specified.
--
.
Examination coverage, beam angle and transducer size are specified.
--
--
Calibration is accomplished on notches and scanning sensitivity is defined and is consistent with the applicable ASME Code require-ments.
No items of noncompliance were identified.
d.
Equipment / Material Certification The inspector audited calibration records of UT instruments S/N 911372 and 773601.
The records included vertical linearity verification reports.
These reports showed that this verification was performed using a mini test block.
The calibration records were current and indicated that the equipment was calibrated properly.
Also, this audit included other certificates of compliance of other inspection material including spot check cleaner batch no. 78J050.
Certifications for this material indicated that the material had been tested in accordance with the Code requirements and had been released for use.
No items of noncompliance were identified.

e.
Personnel Qualification Records The inspector audited qualification records of personnel scheduled to perform NDE's during the current outage.
The records audited identified the discipline in which the individual had been trained and certified.
Additionally, physical examination records indicated whether visual aids were required during the examination.
No departure from SNT-TC-1A (the governing document) recommendations were identified.
No items of noncompliance with regulatory requirements were identified.
f.
Data Review and Evaluation The inspector reviewed the below listed nondestructive examination data to ascertain completeness and accuracy in accordance with the ASME, 8&PV Code,Section XI and regulatory requirements.

The inspector reviewed the above listed records to ascertain that the following items were included:
The methods, technique and extent of examination comply with the
.
ISI program and applicable procedures.
This review revealed an examination was performed using a calibration block (UT-6) which deviated from the committed requirements of the ASME Section XI Code in that the standard was flat versus the requirement to be of the same configuration as the examination surface.
NCR 2-123-80 had dispositioned the deviation "Use As Is" based on the Level III which stated that the use of calibration block UT-6 would not result in a degraded examination of the welds being inspected. In addition to the above deviat. ion, it was found by the inspector that a commitment was made to NRR to use Appendix III of the Winter 1975 Addenda to ASME, B&PV Code.
This appendix requires use of notches or slots to establish sensitivity.
The block UT-6 contains side drilled holes which were used for calibration.
After discussions with the licensee regarding disposition of the above item, the licensee committed to fabricate a calibration block representative of the examination surface and notches inserted in the top and bottom surface as required by the code.
The licensee committed to complete this before the next scheduled refueling outage.
This item will remain unresolved pending the inspector review to establish if any loss of sensitivity occurred during the examination.
(80-21-01)
The recording, evaluation and disposition of findings are in com-
.
pliance with the applicable NDE procedure.
No items of noncompliance with regulatory requirements were identified.

Unresolved Items Unresolved items are matters about which more information is required in order to ascertain whether they are acceptable items, items of noncompliance, or deviations. An unresolved item disclosed during the inspection is discussed in Section 2.f.
