-Observation of Work and Work Activities, Unit 2(73753)
The inspector-observed in-process examination activities. - conducted independent verification examinations, reviewed certification records of NDE materials, and reviewed NDE personnel qualifications-for personnel that had been utilized during the reauired ISI examinations
during this - outage.
The observations, independent examination verifications, and reviews _ conducted by the inspector are documented-below.
(1) The_ inspector observed calibration activities and the in-process
,
ultrasonic (UT) ~ examinations being conducted on 4 Main Steam System welds.
These observations were compared. with. the
.
applicable procedures and the ASME B&PV Code in the following areas: availability of and compliance with approved NDE procedures;. use of knowledgeable ' NDE personnel;. use of NDE personnel qualified to the proper level; type of apparatus used; calibration requirements; scarch 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 DPC equipment, on portions of 2 of the Main Steam. welds. previously observed being examined.
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.
The following listed ultrasonic equipment and materials certification records were reviewed:

2.25 MHz (2) The inspector observed the in-process magnetic particle-(MT)
examinations of 4 Main Steam system circumferential pipe-welds.
The observhtions were compared-with the applicable procedures and the Code.-in the following areas:
examination methods; contrast of dry powder particle color with background; surface temperature; suspension medium for wet particles,-.if applicable; viewing conditions; examination overlap and directions; pole or
,
prod spacing; current or lifting power (yoke); and acceptance criteria.
The inspector conducted MT verification examinations, using DPC equipment, on portions of 2 of the welds previously observed i
being examined.
The examinations were conducted in order to evaluate the technical adequacy of the examination' procedure being used by the licensee to perform examinations and to assess.
the validity of the information being reported by the MT examiners.
The information reported by the MT examiners compared favorably with the verification examinations.
The inspector reviewed documentation indicating that a 10 pound l
lift test had been performed on magnetic particle alternating-
-
'
current yoke MCQA-2 The certification record for the lift. test plate that was used to conduct the test, MCQUA-26041, was:
reviewed to confirm the weight of the test plate.
A review of the magnetic particle material certification record for batch _ numbers 84E010 and 890030 indicated the particles met the applicable specifications requirements.
!
(3) The inspector evaluated 24 radiographic films for RHR Heat Exchanger weld 2RHR-2A-2-3, that had been radiographed under the-licensee's ISI program, 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: penetrameter type, size, and placement; penetrameter sensitivity; film density and density variation;

-(4) 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 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 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 ASME Code; and, results are consistent'with the
-
acceptance criteria.
(a)
In-process tube-data acquisition, including calibration
. confirmation and tube location verifications, was observed for 29 SG-C tubes and 15 SG-D tubes.
r (b)
In-process eddy current data evaluation, including
',
calibration confirmation, was observed for 27 SG tubes.
Primary data-analysis, being conducted by B&W, was observed i
for 11 SG tubes. ' Secondary data analysis, being conducted-by DPC, was observed for 17 SG tubes.
!
(c)
In-process eddy current data evaluation resolution of differences in analysis for reported indications noted by the primary and secondary analysts was observed for 2 steam-generator C tubes.
The inspector co-evaluated' 12' of the SG tubes during the -
,
observations of the primary and secondary analysts evaluations, 10 in SG-C, and-2 in SG-D.
The sanple of evaluations, some having reportable indications and some with no reported indications, was conducted in order to confirm the validity of the reported tubing condition.
The co-evaluation 'analyris conducted by the inspector agreed well with the reported results.
Certification records for EC calibration standards Z-7590 and Z-7877 were reviewed for material type, correct fabrication, and artificial flaw location and size.
!
(5) The inspector reviewed personnel qualification documentation for 28;NDE personnel which included DPC and B&W EC data collection and'EC data evaluation personnel. These personnel qualifications were reviewed in the following areas:

All personnel qualification documentation reviewed indicated that the examiners were qualified for the examinations -being conducted.
d.
Data Review and Evaluation,. Unit 1 (73755)~
(1)' Records of 52 completed ISI nondestructive examinations were selected and reviewed to ascertain whether:
the methods (s),
technique, and. extent of the examination complied with the ISI l
plan 'and, cpplicable NDE procedures; findings were properly j
-
recorded and evaluated by qualified personnel; programmatic j
deviations were recorded as required; personnel, instruments,
calibration blocks, and NDE materials (penetrants, ccuplants)
were designated.
(2) The inspector reviewed the eddy current data analysis results.
.
and a -sample of associated completed records for over 800 SG tubes,'. approximately 200 tubes from each of the four steam
generators.
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.
'
All 'of the examination reports reviewed appeared to contain the-l required examination information including disposition of
'
indications,-if any.
'In the areas inspected,' violations or deviations were not identified.-

Licensee Action on Previously Opened Items (Closed) Inspector Followup Item 50-369, 370/89-15-01, Walking In Cable Trays.
This item resulted from NRC inspectors observing plant personnel using cable. trays as pathways and subsequent discussions with those penonnel which indicated that not all plant personnel are cognizant of '.ianagement's position that using cable trays as a pathway is unacceptable.
The inspector reviewed documents and attendance sign in sheets which indicated that management had transmitted to plant personnel, through memorandum, bulletins, and standup. safety meetings, that the practice of using cable trays as pathways by plant personnel is unacceptable.
Based on the review of the above, this item is considered closed.
