Dear Sirs:
Subject:
Palo Verde Nuclear Generating Station (PVNGS)
Unit 3 Docket No. STN 50-530 Response to Confirmatory Action Letter File: 93-056-026 By letter dated October 4, 1993, (Reference 1), the NRC required that Arizona Public Service Company (APS), provide a written summary of the results of the re-analysis of Eddy Current Testing (ECT) data from Unit 3 third refueling outage (3R3), and the basis for disposition of ail newly identiTied indications.
Based on ECT data from the recent Unit 2 refueling outage, a decision was made to re-evaluate the ECT data from Unit 1 and Unit 3. The re-evaluation of 3R3 rotating pancake coil (RPC) data was performed for specific midspan indications.
This re-evaluation focused on tubes in row 90 and higher and in the area between 07H and the first vertical strap (VS). The findings of the RPC evaluation resulted in the decision to review all of 3R3 bobbin coil eddy current data in the area described above.

U. S. Nuclear Regulatory Commission ATTN: Document control Desk Response to Confirmatory Action Letter Page 2 The enclosure to this letter contains APS's response to the Confirmatory Action Letter, a map of the tubes re-evaluated in Steam Generators 31 and 32, a cumulative report of the non-quantifiable indications (NQI's), possible deposits (PDP's), bowing (BOW), and possible axial indications (PAI's).
Also included are actual Eddy Current graphics of notable indications identified during re-evaluation.
The Unit 3 ECT data re-evaluation was performed using the guidelines as modified for the Unit 1 fourth refueling outage (1R4),
based on the lessons learned from Unit 2.
Should you have any questions, please contact Richard A. Bernier at (602) 393-5882.

ENCLOSURE RESPONSE TO CONFIRMATORYACTION LETTER

'NRC REQUEST'ou will continue to review the Unit 3.ECT data to identify indications which were not identified in refueling outage 3R3 by bobbin coil ECT. Although not documented in your September 29, 1993, letter, you will provide a written summary of the results of this review, and your basis for disposition of all newly identified indications, to the NRC by October 12, 1993. This data and the experience of the Unit 1 ECT inspection willbe used to define the scope of the inspection in Unit 3. The final scope of Unit 3 ECT inspection will be provided to the NRC prior to commencing the inspection.
APS RESPONSE'he Unit 2 Steam Generator Tube Rupture Event Analysis identified an arc-shaped region of the PVNGS Steam Generators susceptible to thermal hydraulic conditions which could create an environment conducive to Outer Diameter Stress Corrosion Cracking (ODSCC).
A re-evaluation of Motorized Rotating Pancake Coil (MRPC) data acquired in the arc of interest during the third refueling outage Unit 3 (3R3), which took place in Fall 1992, was conducted as a result of the findings of the ECT data from 2R4.
During this review, two indications were observed in Steam Generator 31 which could not be characterized due to the use of a single coil pancake probe, and as a conservative measure, all available bobbin data for rows 90 and higher, were reviewed for both Steam Generator 31 and 32.
This review included bobbin data for 3072 tubes in Steam Generator 31 and 1358 tubes in Steam Generator 32.
The review was conducted using the analyst guidelines similar to those developed for the 1R4 outage based on lessons learned from the 2R4 outage ECT inspections.
Each analyst was trained and tested to these guidelines prior to analyzing 3R3 bobbin data.
The results of this review are attached to this response.
The disposition of indications in Steam Generator 31 includes three which have shown no change from previous data, one plugged tube, one weak non-quantifiable indication (NQI), one short (0.34") possible axial indication (PAI) and one NQI with absolute drift.
The three indications which have not changed since the previous outage in 1991, do not appear to be actively growing defects.
The plugged tube is not in service and, therefore,
'ot a concern.
Based on the critical flaw size analysis performed by APS, the short PAI would not be expected to rupture for Main Steam Line Break (MSLB) pressure, even if it penetrates through wall.
The R144C57 tube NQI has some characteristics unique among the NQI's found which cannot be resolved without MRPC inspection.
The absolute drift signal in the area around the NQI is approximately four to eight inches in length and may be indicative of intergrannular attack or stress corrosion. cracking, and there is indication of a deposit on the tube at the elevation of the NQI.
However, the bobbin probe does not allow the analyst to determine if the deposit and NQI are at the same azimuth, and an MRPC inspection is necessary to resolve the issue.
f The NQI in Steam Generator 32 is weak, and it was not evident in the 1991 data of 3R2.
It requires MRPC to further characterize it.
APS analysts have completed the review of ECT data from 3R3, the results of which are included in the following pages.
This data and the Unit 1 ECT data, which is being gathered during the ongoing refueling outage, will be used to determine if additional actions are necessary for the continued operation of Unit 3.,
With over 80% of the arc of interest in both Unit 1 Steam Generators inspected, there has been no pattern of axial indications identified in Unit 1
~ Although the inspection in Unit 1 is not complete at this time, the evidence from the Unit 1 inspection supports the hypothesis that enough differences exist between the units to conclude that accelerated tube degradation, as experienced in Unit 2, is not expected to occur in Unit 1 and Unit 3.
As stated in Reference 2, administrative controls on primary coolant dose equivalent iodine and enhanced leak detection methods provide assurance of prior warning to a tube rupture event and limit offsite dose consequences to less than 10CFR100 limits.
In summary, the continued operation of Unit 3 until the proposed midcycle outage does not present an undue risk for the following reasons:
the PAI identified by RPC in Steam Generator 31 (R99C148),
is short and may be volumetric; the evidence from Unit 1
inspections in progress do not presently show the Unit 2 failure mechanism to be fully transportable; enhanced leakage monitoring improves our ability in the identification of the precursors to a tube rupture event; and the safety assessment discussed in Reference 2, demonstrates that even in the unlikely event of a MSLB with consequential multiple tube ruptures, with.the proposed administrative limits on reactor coolant system dose equivalent iodine, and the reduction in the CPC variable overpower setpoints, the resulting offsite doses are less than 10CFR100 limits.
