Observation of Work and Work Activities, Unit 3 (73753)
The inspector observed work activities, reviewed certification records of NDE equipment and materials, and reviewed NDE personnel qualifications for personnel that had been utilized during the required ISI examinations during this outage.
The observations and reviews conducted by the inspector are documented below.
The inspector observed calibration activities and the in-process ultrasonic (UT) examinations of 4 High Head Safety Injection, 8" diameter, circumferential pipe welds being examined by EBASCO examiners.
These observations were compared with the applicable procedures and the ASNE BSPV Code in the following areas:
availability of and compliance with approved NDE procedures; use
0'
of knowledgeable NDE personnel; use. of NDE personnel qualified to the proper level; type of apparatus used; calibration requirements; search units; beam angles; DAC curves; reference level for monitoring discontinuities; method of demonstrating penetration; extent of weld/component examination coverage; limits of evaluating and recording indications; recording significant indications; and, acceptance limits.
The inspector conducted an independent ultrasonic verification examination, using EBASCO equipment, on portions of 3 of the Safety Injection welds previously observed being examined by the EBASCO ultrasonic examiners.
These examinations were conducted in order to evaluate the technical adequacy of the ultrasonic examination procedure being used by the licensee and to assess the validity of the information being reported by the ultrasonic examiners.
The verification ultrasonic examinations conducted by the inspector indicated that the procedure being used to conduct the examinations is adequate and the verification examination results compared favorably with the information being reported by the ultrasonic examiners.

specified method, penetrant materials identified; penetrant materials analyzed for halogens and sulfur; acceptable pre-examination surface; surface temperature; surface drying time prior to penetrant application; method of penetrant application; penetrant dwell time; method used for excess penetrant removal; surface drying prior to developing, if applicable; type of developer; examination technique; evaluation technique; and, reporting of examination results.
The NRC inspector re-evaluated one of the above observed welds following the PT examiners evaluation of the welds but prior to the developer being removed from the weld surfaces.
This re-evaluation was conducted in order to determine if the evaluations performed by the PT examiners was in accordance with the applicable procedure acceptance criteria and to determine if the examination results were being reported as required.
The re-evaluations conducted by the NRC inspector indicated that the proper evaluation was made by the PT examiners and that the examination results were being reported as required.
The inspector's review of the below listed liquid penetrant materials certification records indicated that the sulfur and halogen content of the material was within acceptable content limits.
Materials Batch Number Liquid Penetrant Cleaner/Remover Developer 89F06K, 89K039 87M025 888019 The inspector reviewed records indicating that a
10 pound lift test had been performed on magnetic particle (MT) alternating current (AC) yokes 1784 and 811.
The certification record for the lift test plate that was used to conduct the tests, No. 4, was reviewed to confirm the weight of the test plate.
A review of the magnetic particle material certification record for batch number 87D005 indicated the particles met the applicable specifications requirements.
The inspector observed one in-process visual (VT) examination.
This examination was being conducted on a
14" diameter Regenerative Heat Removal pipe, variable spring hanger, and included the hanger structural members.
This observation was made to:
determine whether the applicable drawing, instructions or travelers clearly specify the procedure to be used and that a
e
copy of the procedure is available in the area where the work is being performed; identify for record review the personnel performing the examination and ascertain whether they are qualified to perform the assigned task; determine whether the required tools and examination aids (as specified in the examination procedure)
are available at the work location; determine whether the specific areas, locations and extent of examination are clearly defined; determine whether the test attributes are as specified in the applicable test procedure; ascertain whether the defects are evaluated in accordance with the procedure requirements, correct acceptance criteria is used, and the inspection results are reported in a prescribed manner.
The NRC inspector conducted an independent examination of the item previously observed being examined by the EBASCO visual examiners.
This examination was conducted in order to evaluate the adequacy of the examination procedure being used by the licensee's contractor and to assess the validity of the, information being reported by the examiners.
This re-examination generally agreed with the results reported by the visual examiners.
Steam Generator Tubing Eddy Current Examination The inspector observed the EC activities indicated below.
The observations were compared with the applicable procedures and the Code in the following areas:
method for maximum sensitivity 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 recalibrated at predetermined frequency; required coverage of steam generator tubes occurs during the examination; acceptance criteria is specified or referenced and is consistent with the procedure or the ASHE Code; and, results are consistent with the acceptance criteria.
(a)
In-'process tube data acquisition, incIuding calibration confirmation and tube location verifications, was observed for 24 SG-B tubes.
(b)
In-process eddy current data evaluation, including calibration confirmation, was observed for
SG-8 tubes.
These observations included both primary and secondary data analysis.
The NRC inspector co-evaluated 14 of the SG tubes during the observations of the primary and secondary analyst's evaluations.
The sample of evaluations, some having reportable indications and some with no reported indications, was conducted in order to
'J0
confirm the validity of the reported tubing condition.
The co-evaluation analysis conducted by the inspector agreed well with the reported results.
Certification records for EC calibration standards Z-1545, Z-1546, and Z-1547 were reviewed for material type, correct fabr ication, and artificial flaw location and size.
(6)
The inspector reviewed personnel qualification documentation for
NDE examiners which included EC data collection and EC data analysis personnel.
These personnel qualifications were reviewed in the following areas:
employer's name; person certified; activity qualified to perform; current period of certification; signature of employer's designated representative; basis used for certification; and, annual visual acuity, color vision examination, and periodic recertification.
The NDE personnel appeared to be adequately qualified in all cases reviewed.
