Inservice Inspection The inspector reviewed documents, records and examination activities, as indicated below, to determine whether ISI was being conducted in accordance with applicable procederes, regulatory requirements, and licensee commitments.
The applicable code fnr ISI is the American Society of Mechanical Engineers Doiler and Pressure Vessel (ASME B&PV) Code,Section XI,1980 edition with addenda through Winter 1980.
Duke Power Company (DPC) NDE personnel performed the liquid penetrant (PT), magnetic particle (MT), and radiographic (RT) examinations, while Babcock and Wilcox (B&W) personnel, assisted by DPC personnel, conducted the majority of the ultrasonic (UT) examinations. Steam generator (SG) tubing eddy current (EC)
examination data collection was accomplished by DPC personnel with B&W personnel performing the primary data analysis and Zetec and DPC personnel performing a secondary data evaluation.

Only current revisions were reviewed during
.
this inspection.
(2) The inspector reviewed the Ultrasonic (UT) procedures to ascertain whether they had been reviewed and approved in accordance with the licensee's established QA procedures.
The procedures were also reviewed for technical adequacy and conformance with ASME,Section V. Article 5 and other licensee commitments / requirements in the following areas:

(3) The inspector reviewed the Eddy Current -(EL) procedure for technical content relative to:
multichannel examination unit, multichannel examination indication equipment is specified, examination sensitivity, material permeability, method of examination, method of calibration and calibration sequence, and, acceptance criteria.
(4) The inspector reviewed the Radiographic (RT) procedure to determine whether it contained sufficient information to assure that the following parameters were specified and controlled within the limits permitted by the applicable code, or any other l
specification requirement:
type of material to be radiographer; material and weld surface condition requirements; type of rcdiation source, effective focal spot or effective source size; film brand or type; number of films in cassette; minimum source to film distance; type and thickness of intensifying screens and l
' --
filters; quality of radiographs; film density and contrast for single and composite viewing; use of densitometers for assuring compliance with film density requirements; system of radiograph identification; use of location markers; methods of reducing and testing for back-catter; selection of penetrameters including penetrometer placement; number of penetrameters; shims under penetrameters; radiographic technique for double wall viewing; and, evaluation and disposition of radiographs.

(5) The inspector reviewed the liquid penetrant (PT) procedure to ascertain whether it had been reviewed and approved in accordance
,
with the licensee's established QA procedures. The procedure was l
also reviewed for technical adequacy and conformance with ASME,Section V, Article 6, and other licensee requirements in the i
l following areas:
specified method; penetrant materials analyzed for sulfur; penetrant material identification; penetrant I
materials analyzed for total halogens; surface temperature; acceptable pre-examination surface conditioning; method used for pre-examination surface cleanir,g; surface drying tin.e prior to penetrant application; method of penetrant application; penetrant dwell time; method used for excess penetrant removal; if
i
'
applicable, surface drying prior to developer application; type of developer; examination technique; evaluation techniques; and, procedure requalification.
c.
Observation of Work and Work Activities, Unit 2 (73753)
l The inspector was unable to observe in-progress examination activities during this inspection because all examinations had been completed.
The inspector conducted independent examination verifications, using the licensee's equipment, in the areas of radiography and cddy current.
The inspector also reviewed NDE equipment certification records and reviewed NDE personnel qualifications for personnel that
,
l had been utilized during the required ISI examinations during this
,
outage.
The independent verifications and reviews conducted by the l
inspector are documented below.
(1) The inspector independently evaluated 131 radiographic films for the 5 Main Steam, 3 Main Feedwater, and 2 Auxiliary Feedwater systems pipe welds that were radiographer under the licensee's ISI program.
These evaluations were conducted in order to determine if the radiographic quality was in accordance with the
applicable procedure and ASME Code requirements and to specifically verify the following: penetrometer type, size, and l
placement; penetrometer sensitivity; film density ar.d density variation; film identification; film quality; weld coverage; and,
'
disposition of the welds radiographer.
The inspector's evaluation of these radiographs indicated that the welds were properly examined and that the radiographs were adequately evaluated.
However, during these reviews, differences were noted between the ISI plan and some of the welds relative to the thickness of the weld being radiographer.
While reviewing the 5 Main Steam welds, the inspector noted that the weld thickness noted on the radiographic technique sheets for three of the welds were different from the weld thickness stated in the ISI plan.
Because the difference between the ISI plan thickness and the pipe weld thickness shown on the radiographic technique sheets resulted in a change in penetrometer requirement l

by the ASME code, the inspector requested an explanation from knowledgeable licensee personnel.
The thickness of 2 of the
>
I welds had beei, determined ultrasonically and the third weld thickness had been established by physical measurement.
All three of the welds were determined to be thicker than what was j
stated in the ISI plan and as a result of this determination the l
penetrometer. requirement was based on the actual weld thickness.
l The inspector reviewed the two ultrasonic thickness reports and the statement of physical measurement for the third weld.
The l
l change of penetrometer requirement in all three cases was in accordance with the ASME code.
The licensee is revising the ISI plan to reflect the actual weld thickness for these three welds.
The inspector confirmed the calibration watus for Densitometers MCQA-1479 and MCQA-1640 to ascertain whether the documentation was complete and accurate.
The inspector verified the qualifications for S radiographic examiners.
The qualifications were reviewed for the following:
employer's name; person certified; activity qualified to perform; effective period of certification; and, annual visual acuity and periodic decertification.
(2) The inspector independently evaluated the EC examination dd,t for 100 SG tubes.
A random sample of 25 tubes.in each of tle * SG's were evaluated in order to determine adherence to the applicable procedures and the Code in the following areas:
method for maximum sensitive is applied; method of examination has been recorded; examination equipment has been calibrated in accordance with the applicable performance reference; amplitude and phase angle have been calibrated with the proper calibration reference and is recalibrates at predetermined frequency; required coverage of steam generator tubes occurs curing the examination; acceptance criteria is specified or referenced and is consistent with the procedure or the ASME Code; and, results are consistent with the acceptance criteria.
The inspector's evaluation indicated that the tubes appeared to be correctly evaluated by the analysts and that any noted indications were being reported as required.
d.
Data Review and Evaluation, Unit 2 (73755)
(1) Records of completed ISI nondestructive examination:s for 30 PT, 10 MT, 27 UT, and 10 RT examinations were selected and reviewed to ascertain whether:
the methods (s), technique, and extent of the examination complied with the ISI plan and applicable NDE procedures; findings were properly recorded and evaluated by qualified personnel; programmatic deviations were recorded as required; personnel, instruments, calibration blocks, and NDE materials (penetrants, couplants) were designated.

(2) The inspector reviewed the eddy current data analysis results and l
a sample of associated completed records for 200 SG tubes. Fifty tubes from each of the four SG's were selected for this review.
The reviews were compared with the applicable procedures and the ASME B&PV Code in the following areas: the multichannel eddy current examination equipment has been identified; material permeability has been recorded; method of examination has been recorded; and, results are consistent with acceptance criteria.
No discrepancies were found which would have significant impact on the results of the examinations.
I In the areas inspected, violations or deviations were not identified.
