Inservice Ins ection - Review of Pro ram
'a ~
Pro ram'
royal The Inservice Inspection (ISI) program plan was submitted to the NRC:NRR for review and approval in licensee letter ANPP-33266-EEYB/
KLM of August 26, 1985.
The NRR response to this initial submittal is contained in Safety Evaluation Report (SER), Supplement No. 9, of December 12, 1985.
The SER response was a preliminary conclusion stating that the sample of welds and component supports selected for inservice examination significantly exceeds the requirements of ASME Code Section XI, 1980 Edition, including addenda through winter 1981.
The NRR latest response to the ISI program plan is contained in an October 21, 1987, letter from Mr. E. A. Licitra to Mr. E.
E.
Van Brunt, Jr.
The Unit 2 ISI plan is described in a document entitled, "Inservice Inspection Program Summary Manual," Program No. ISI-2, Revision',
of May 29, 1986.
The ISI program review was documented on a cover sheet which indicated the following:
a technical review, Engineering Manager's approval, Authorized Nuclear Inservice Inspector's (ANII) concurrence, and the Plant Review Board's approval.
The ANII services were procured from the Kemper Group under the Lumbermens Mutual Casualty Compan b.
Pro ram Or anization Administrative Procedure No.
73AC-OZZ10 entitled,
"ASME Section XI Inservice Inspection," Revision 2, of March 30, 1987, establishes the methods for preparing, controlling, and implementing the ISI program.
This procedure requires the ISI program summaries (plans and schedules)
to be submitted to the NRC at least 90 days (or as required by the operating license) prior to the first refueling outage for each specific unit.
This procedure also defines the responsibilities of the persons involved with the final evaluation and acceptance of the ISI results.
This information is documented in the "ISI Summary Report."
Section 5.6.1 requires the following records to be stored and maintained for the life of the plant:
ISI Program Summaries, ISI Summary Reports, all Examination Data Sheets and associated material, and equipment and personnel certifications.
The licensee's repair and replacement program is addressed in Administrative Procedure No. 30AC-9ZZ01, Appendix G.
Appendix G
meets the requirements for a Repair Program as specified in Article IWA-4000 of the ASME Code Section XI and IWA-7000 for a Replacement Program.
'dministrative Procedure No. 73AC-OZZ21, entitled, "Qualification and Certification of NDE Personnel,"
Revision 4, of April 13, 1987, establishes the qualification, training, certification, and recertification of NDE personnel at al'1, levels.
This procedure, for personnel qualification, is consistent with ASME Section XI and
'NT-TC-lA ( 1980 Edition) requirements.
c ~
ua1 it Assurance Pro ram The "Operations Quality Assurance Criteria Manual," Criterion 9, addresses requirements for the control of special processes.
This requirement is implemented by Administrative Procedure Nos.
6N417.12.00, Revision 3, entitled, "Quality Monitoring Activities,"
and 6N417. 13.00, Revision 2, entitled, "Quality Auditing."
Section 4.1.5 of the latter procedure requires a matrix be developed to assure that all required Technical Specification audits are covered.
This is addressed in Audit Scoping Matrix 9, which covers audits of special processes including the ISI program.
The inspector verified that these audits or monitoring activities are conducted by qualified QA personnel.
The QA program also contains provisions to oversee contractor/subcontractor ISI activities.
During this Unit 2 outage, quality monitoring ISI/NDE reports were performed on special processes on February 15, 16, and 23, 1988, and March 3, 1988.
No violations or deviations were identified.
3.
Inservice Ins ection - Review of Procedures The latest revisions of the following NDE procedures were reviewed by the inspector to assure compliance with the ISI program:
a.
73TI-9ZZ06, Revision 3, of February 9, 1988,
"Wet Magnetic Particle Examination."
b.
73TI-9ZZ12, Revision 1, of October 12, 1987, "Ultrasonic Examination of Nozzle Inner Radius Areas."
'.
73TI-9ZZ17, Revision 1, of September 3, 1987, "Visual Examination of Welds and Bolting."
d.
73TI-9ZZ18, Revision 2, of September 3, 1987, "Visual Examination of Supports Components."
All procedures specified qualification and certification of NDE personnel in accordance with 73AC-OZZ21 or another approved program.
The methods of recording, evaluating, and dispositioning findings and reporting requirements were addressed in the procedures in accordance with the applicable Code requirements.
The technical content, such as, method of examination, extent, and technique, were adequately described in conformance with the requirements and guidance of ASME Code Section V.
No violations or deviations were identified.
Inservice Ins ection - Observation 'of Work and Work Activities The inspector reviewed the qualification and certification records of the NDE personnel performing the ISI examinations.
All personnel appeared qualified in accordance with ASME Section XI requirements.
In conjunction with these examinations, the inspector reviewed the equipment certifications,. and these were found acceptable.
5.
Due to scheduling changes, the licensee was not able to perform any ISI examinations during this inspection.
ISI examinations are scheduled later during this outage, and these will be observed by NRC inspectors and reported on in Inspection Report No. 50-529/88-10.
No violations or deviations were identified.
Inservice Ins ection - Data Review and Evaluation The inspector reviewed all the available NDE ISI data sheets generated during this outage, on approximately 350 ISI examinations, that had been reviewed and approved by a Level III reviewer and an ANII.
Only a couple of discrepancies were found on report numbers 88-2131 and 88-2132, in that these MT repor ts identified the wrong pipe size.
These two discrepancies were administrative in nature and did not contain any safety-related concerns and were corrected by the licensee when identified.
At the time of this inspection, out of the approximately 350 ISI examinations performed, ten rejected examinations were identified.
Eight of the ten reje'cted examinations were found by magnetic particle testing (MT), one by liquid penetrant testing (PT)
and one visual test (VT) found a loose lock nut.
The licensee was in the process of performing corrective action and reinspection, and had already cleared and accepted five of the eight rejected MT examination t
No violations or deviations were identified.

~Ei M ti The inspector met with the licensee management representative denoted in paragraph 1 on March 25, 1988.
The scope of the inspection and the inspector's findings as noted in this report were discussed.
