The da a was being recorded in order to establish the orientation and dimensions of the indication necessary in order to determine the accepta-bili ty o'f the indication relative to the acceptance criteria in ASME B&PV Code Section XI. This particular indication appeared to be very near the interface between the RV ferritic steel plate base material and the stainless steel cladding on the inside surface of the R Subsequent discussions with AP, SCS, and W personnel disclosed that an additional small indication had been noted during the Weld #6 examination. This indication is located approximately 323" below the RV flange, some 48" below the other indicatio Further discussions with the licensee disclosed that during this inspection, volumetric indications were detected during the examination of Weld #7, the other lower shell course longitudinal weld. Also, indications were detected during an ISI examination in 1984, in the Loop 2, outlet nozzle-to-shell weld, designated as Weld 21 on drawing ALA-1-1100, and this weld is scheduled to be examined during this inspectio The licensee has decided to enlist the aid of an additional ultrasonic inspection system, UDRPS, to assist in the

! indication dimensioning and positioning process because the ir.dications adjacent to Weld 6 appear to be very near the l

'

clad /basemetal interface and may have to be declared surface indications under the standards for evaluation in l the ASME B&PV Code and may possibly fall into a rejectable l categor Also, the licensee wishes to utilize the UDRPS I to better characterize the indications noted in Weld 21.

Not all of the RV weld examinations had been completed by the end of this inspection and the final dimensioning and subsequent disposition of the dctected indications had not been completed. The inspectors informed the licensee that in order to track and later review the final disposition of the currently known indications and any other indications that might be identified during the remaining RV examinations, that the following item would be opened and identified as IFI 50-348/88-14-01, Fina l Disposition of Reactor Vessel Indication (b) In association with the examinations of the reactor vessel welds utilizing the W remote examination tool, the inspectors reviewed the "Reactor Vessel Examination Program Plan" to confirm the extent of weldment coverage, calibration requirements, search units, search unit overlap requirements, beam angles, DAC curves, reference level for indication detection, and indication recording limit (c) The circumferential examination of Welds 16 thru 20, on Sketch ALA-2-4101, required the use of a 30 shear wave examination because a 45 sound beam does not extend to the I.D. of the pipe due to the ratio of pipe 0.0 /I.D. ard the thickness of the pipe wall. The inspectors observed and independently verified the ultrasonic equipment calibration on calibration Block Number ALA-030 with the 30 shear wave probe and observed portions of the circumferential examination of these welds with the 30 shear wav (2) The inspectors conducted an ultrasonic verification examinaticn, using W equipment, on portions of Weld 16, Sketch ALA-2-410 The examination was performed in order to evaluate the technical adequacy of the ultrasonic examination procedure being used by

the licensee's contractor to perform ultrasonic examinations and to assess the validity of the information being reported by the ultrasonic examiners, The verification examination indicated

! that the procedure used to conduct the examinations appears to l be adequate for the application and the reported information compared favorably with the verification examinatio (L) The following listed ultrasonic equipment and materials certification records were reviewed:

tested to the requirements of Section XI of the ASME Code and that the examinations and tests be completed during each of four ten-year intervals. The ten-year intervals are calculated from the start date of commercial operation of the facilit The date of commercial operation for Farley Unit 1 is December 1,1977, and the first interval examinations and testing should have been completed in 1987. However, since Section XI of the ASME Boiler and Pressure Vessel Code allows extension of the interval of up to one year so that the interval can be made to correspond to a plant's outage schedule, the final completion date allowed by the code fer the first interval examination and testing on Unit 1 will be December 1, 1988. However, the licensee's hydrostatic program for the first interval was complete and testing in progress this outage was for the first period of the second interva The inspector reviewed the ISI program for ASME Code Class 1, 2 and 3 components, the ten year inspection plan for ASME Class 1 and 2 components, the ten year inspection plan for ASME Class 3 components and six hydrostatic test procedures. Test procedure interfaces of systems were confirmed and select relief requests were also examined to determine if the licensee had invoked the relief granted as requeste The six ASME Class 2 hydrostatic test procedures listed below were reviewed for technical content and the hydrostatic boundaries were re-established on drawings using the procedure's valve line-up sheets to verify test completenes Test N Procedure N Description of Test Hydro No. 8 FNP-1-STP-16 CVCS Low Pressure Letdown Hydro No. 9 FNP-1-STP-16 VCT, Connecting Lines and Charging Pumps Suction Hydro No. 11 FNP-1-STP-160.11 Letdown Line from 600 PSI Piping to VCT Hydro No. 13 FNP-1-160,13 Train 8 Main Steam, Main Feedwater, Aux.

procedures were well written, valve lineup sheets listed all valves within the test and second verifications of the valve positions were performe Test boundary changes required because of the mode of operation were reconcile Responsible test personnel were knowledgeable of their systems and test requirements and final test records were complete and auditabl However, the inspectors review did reveal two findings that the licensee was requested to take action on because they affected the second interval program. These findings and the initial verbal licensee responses are as follows: Valve QV-198 was listed in first interval plan as a test boundary valve. This valve was identified on Drawing D-175039 as QV-19 Further review revealed the plan to be accurate and the drawing to be in erro This drawing error was also carried over to the second interval drawings. The licensee committed to revise the drawing to clarify the valve's identificatio The licensee's action will be tracked with Inspector Followup Item 50-348/88-14-02, Valve QV-198 is Incorrectly Identified on CVCS Drawing 0-175039 Rev. 22 Sheet The inspector reviewed the second interval plan to determine if the tests performed during the first interval, to the 1974 Edition of the ASME Code, were scheduled correctly with the requirements of the 1983 Edition of the Code that will be used for the second interval test The inspectors discovered that the tests were not scheduled in accordance with Table IWC-2500-1, Note 5, of the 1983 Edition of the Cod The licensee stated that the seccnd interval tests were scheduled as delineated in the plan to prevent too many tests falling in the last period of the interva The licensee however, agreed that a relief request or plan modification was applicable and agreed to take appropriate corrective action. This item will be tracked with Inspection Followup Item 50-348/88-14-03, Second Interval Hydrostatic Test Schedulin In addition to the above, the inspectors reviewed the program and relief requests for Class 3 components. The review of relief requests was conducted only on Class 3 components because the licensee had requested relief from the hydrostatic test requirements on the entire Class 3 program with the exception of portions of the auxiliary feedwater system and portions of the chemical and volume control systam. The inspector's review revealed that the actual relief requests were not definitive and lacked technical basis. In addition, NRC's Safety Evaluation Report for the service water, component cooling water, and chemical and volume control systems was written such that, it appeared to the inspectors that the NRC reviewer had not granted relief to the extent requested in the progra The licensee contacted the inspectors by telephone on April 18, 1988, and stated that NRC (NRR) would be contacted to determine whether the extent of the relief requested for these systems, had been grante Clarification would also be requested of the Safety Evaluation
