The inspector conducted en independent ultrasonic verification examination, using SCS equipment, on portions of. 3 of the pressurizer safety and relief valve welds previously observed being examined.

These examinations were conducted in order to evaluate the technical adequacy of the ultrasonic examination i

procedure being used by the licensee and to assess the validity

'

of the information being reported by the ultrasonic examiners, j

The verification ultrasonic examinations conducted by the inspector indicated that the procedure being used to conduct the i

examinations' is adequate and the verification examination l

results compared favorably with the information being reported

-

by the ultrasonic examiners.

The following ~ listed ultrasonic equipment and materials certification records were reviewed:

131-D-307A, ISI-D-319A, and ISI-D-315A (2) The inspector observed. the in process liquid-penetrant (PT)

examinations of 2 circumferential piping-welds. One weld was a 4" safety injection system weld, weld number. 3 on sketch 151-11201-29. and the other was a 2" main loop crossover drain line weld, weld number 1 on sketch ISI-11201-031.

In addition-to the 2 welds = above, the-inspector observed the in process examination of an integral attachment weld to a 6" safety injection' system pipe.

This attachment weld was designated as weld number 27 on sketch SIS-11204-039. These observations were-

.

compared with the applicable procedure and the ASME B&PV Code in the following areas:

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 the main coolant-loop crossover drain line weld and the integral attachment weld following the PT examiners evaluation of the welds but prior to the developer being removed from the weld surfaces. These re-evaluations were conducted in order to determine if the evaluations performed by the PT examiner 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 87A045 Cleaner / Remover 89L01P, 89E04K Developer 88H043 (3) The inspector observed the in-process magnetic particle (MT)

examinations of 3 steam generator number 4 auxiliary feedwater circumferential welds, numbers 40, 41, and 42.

These

- !

observations 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.

During the examination of weld 40, two exial direction linear indications, one approximately 3"

long and the other i

approximately 7" long in the pipe spool piece adjacent to the weld, were detected by the examiners.

Final disposition of these indications had not been determined at the conclusion of this inspection.
