DOCKET NOS. 50-445 AND 50-446 INSPECTION REPORT NOS. 50-445/85-07 AND 50-446/85-05 CLARIFICATION OF SUPPLEMENTAL RESPONSE TO NOV 445/8507-01 AND 446/8505-01 REF: 1) TUGC0 letter TXX-4727 from W. G. Counsil to E. H. Johnson dated April 2, 1986

2) TV Electric letter TXX-6211 from W. G. Counsil to the NRC dated January 28, 1987 Gentlemen:

In further review of our supplemental letter identified in Reference 2, we have determined that a clarification to the subject response is required. The supplemental request for information for Notice of Violation 445/8507-01 and 446/8505-01 (Reference 2) has been restated to aid in understanding our

revised response.

NOTICE OF VIOLATION ITEM 1 (445/8507-01 AND 446/8505-01)

SUPPLEMENTAL REQUEST FOR INFORMATION We find that the corrective steps taken and results achieved do not indicate that the installation of the replacement RTE-Delta Potential Transformer tiltout assembly was reinspected and accepted. Also, there is no indication that these deficiencies were documented on a nonconformance report for Units 1 and 2.

REVISED SUPPLEMENTAL RESPONSE TO ITEM 1 In our response, we noted the deficiencies involving the Unit 1 RTE-Delta Potential Transformer Tiltout assemblies were corrected using startup work permits. We failed to note that inspections and the acceptance of completed work are inherent in the startup work permit program. We have confirmed these activities were accomplished as documented on the completed work permits (Z-2912 & Z-2914).

l REVISED SUPPLEMENTAL RESPONSE TO ITEM 1 - CONT'D i As noted in our review of a previous NRC finding (445/8407-01), the program for managing 10CFR21 defects was not positively controlled. In some cases, and the case of the RTE-Delta 10CFR21 notice involved in this finding, the deficiencies were corrected without nonconformance reports. Our current programs for reportability evaluation and nonconformance control are specified in procedures NE0 CS-1, " Evaluation of and Reporting of Items / Events under 10CFR21 and 10CFR50.55(e)," and NE0 3.05, " Reporting and Control of Nonconformances." Procedure NE0 CS-1 requires personnel to notify the Site Coordinator upon receipt of 10CFR21 information. The Site Coordinator is required to transmit the documented information concerning a potentially 1

significant item to the appropriate manager in the Nuclear Engineering and Operations group. Procedure NE0 3.05 states that Engineering and Operations are responsible for initiating or requesting Nonconformance Reports (NCRs),

where required, for identified nonconformances. These programs should ensure that 10CFR21 notifications are evaluated and any required NCRs are initiated.

Our previous response incorrectly indicated that the Ur.it 210CFR21 deficiencies were corrected in August 1985. The work was actually completed in September 1985 and QA/QC review of the work packages was completed in April 1986.

Very truly yours, i
