4' bservation of York and Work Activities Unit 2(73753)

'The inspector observed work activities and reviewed certification records of equipment, materia'3, and NDE personnel which had been and will be utilized .during the required ISI examinations during this outage. The observations and reviews conducted by the inspector are

, documented belo (1) Ultrasonic (UT) Examination (a) The inspector observed calibration activities and the in process ultrasonic-examinations being conducted on the welds indicated below. The observations were compared with the applicable procedures and the Code in the following areas: availability of ~ and compliance with approved NDE procedure; use of knowledgeable NDE personnel; use of NDE personnel qualified to the proper level; t' pe y of apparatus used; extent of coverage of weldment; calibration requirements; search units; beam angles; DAC curves; reference level for monitoring discontinuities; method of demonstration; recording significant indications; and, acceptance limit Weld ID ISI Item N NI2F-529 B09.011.415 2NI2F-531 B09.011.416 2NI2F-532 B09.011.417 ,

While observing the examination of the above listed welds, '

the NRC inspector became ' concerned with the examinations because the geometric reflectors, that had been reported during the previous UT examination in October 1979, were not being observed during this examination of weld 2NI2F-529 and the geometric reflectors that had been reported on weld 2NI2F-531 were not clearly discernable nor at an amplitude that would warrant there being recorded.

i Also, in both cases, the UT signal from these areas had a very high noise level signal, however, this is not particularly unusual for stainless steel material.

l Following completion of these examinations, the NRC l: inspector expressed his concern to the ISI supervisor. The

'

ISI supervisor indicated that there had been a similar l

problem on an additional weld and that the resson for the L differences in the UT examinations had not yet been resolve The NRC inspertor requested that two sets of UT equipment

! be calibrated. One set was to utilize the transducer used l for the above examinations on a alffer-T.c UT instrument and l

-3 the other set was to utili7e a different transducer on the UT instrument. that sas used during the examination Following these calibrations, weld 2NI2F-529 was to be re-examined to deteroine if the examination differences could be attributed to a faulty transducer or possible a UT instrument proble During the UT equipment calibrations mentioned above, the UT examiner discovered that he had inadvertently been using a 5.0 MHz transduce; instead of a 2.25 MHz transducer for his examinations which could account for the differences because the 1979 examinations had been made using a 2. 25 MHz transducer. The use of 5.0 MHz transducer is permitted by procedure and code for these examinations, however, the 2.25 MHz transducer has superior penetration power and is used almost exclusively when examining stainless steel material. Discussions with the UT examiner indicated that he had been unaware of his error and had intended to use a 2.25 MHz transducer f ar these examinations in an effort to match the equioment used during the 1979 examination Following the calibration of two sets of equipment with one set utilizing the 5.0 MH7 transducer used during the current examinations and the other set utilizing a 2.25 MHz transducer, the NRC inspector observed portions of the re-exsmination of weld 2NI2F-52 The re-examination indicated no change with the 5.0 MHz transducer, however, with the 2.25 MHz transducer the geometric :sflectors that hau been reported during the 1979 examination were very evident and correlated very closely with the 1979 examination reported result The NRC inspector discussed the above findings with the ISI supervisor and requested that all of the welds that had been examined with a 5.0 MHz transducer be re-examine These re-examinations were accomplished during this L

inspection and the NRC inspector reviewed the re-examination results. The current examination utilizing a 2.25 MHz transducer and the reported 1979 UT results were compared and there did not appear to be any significant discrepancies between the two examination (b) The NRC inspector conducted an ultrasonic verification examination, using B&W equipment, or, portions of the below listed welds. The examinations were performed in order to

! evaluate the technical adequacy af the ultrasonic

! examination procedure being used , the licensee's contractor to perform ultrasonic examinations and to assess i the validity of the information being reported by the l ultrasonic examiners.
