S. Nuclear Regulatory Commission Document Control Desk Washington, DC 10 CFR Part 21 Interim Report 20555'ubject:

R. E. Ginna Nuclear Power Plant Docket No. 50-244 The revision to 10 CFR Part 21, Section 21(a) made effective on 10/29/91, requires an. interim report; of any deviation for which an evaluation to determine reportahility impact is. unable to be completed. within 60 days of discovery.

A recent RG&E audit found that. evaluations for several deviations the need for interim reports had not yet were not timely and.

been considered.

to be implementation Itthat further, determined the cause of the problem deficiencies corresponding'to'he rule change.

The magnitude of the problem was 28 evaluations exceeding the 60 day duration. This total was derived from an audit sample, from the nearly 200 open Nonconformance Reports (NCR), and further investigation by. the NCR processing group. During the past four weeks a concerted effort was undertaken to complete the 28 evaluations. The following, tabulation presents the current status:

Evaluation Completed -- No Reportable Defect -- 25 Evaluation In Progress -- Included in Interim Report -- 2

Evaluation Completed; -- Reportable Defect -- 1 *

• Notice dated February 24 sent by facsimile The two deviations requiring additional evaluation time are described in Attachment A. The actual discovery date for'ach preceded the rule change that became effective 10/29/91. For these deviations, the 10/29/91 date which augments the actual discovery'ate was used to initiate the 60 day evaluation requirement. .Although these deviations were discovered prior to the rule change date, interim reports became necessary prior to 12/28/91 for evaluations continuing into 1992.

In addition to the review of NCRs, other corrective action systems which involve evaluations under. 10 CFR Part 21 have also been reviewed and found to be free of timeliness problems..

The following actions have been undertaken to ensure timely evaluation and interim reporting in, the future.

1. Assigned responsibilities and methods. for. processing an/

statusing deviations have been'larified in all applicable procedures, including Ginna Station and. Quality Performance.

2. Assigned responsibilities and instructions for performing 10 CFR 21 evaluations and. related interim reports have been clarified in existing Ginna. Station', Quality Performance and Nuclear Engineering Services procedures. These clarifications include. utilization of 10CFR 50.72 and, 50.73 criteria for performing evaluations of installed. basic components.

3. Responsibilities and requirements for 10 CFR 21, evaluations and related interim reports have been clarified. in relevant portions of Quality Assurance Manual Sections 15 and 16.

4. Target completion dates are assigned and tracked, for potential deviations to'ssure timely evaluations.

5. Training has been scheduled. for appropriate groups. In the interim, closer monitoring of the evaluation timeliness will be provided by the Quality Performance department.

In summary, corrective actions are sufficiently implemented, to assure timely evaluation of 10 CFR 21 deviations. Interim actions will remain until required. training is completed.

Further correspondence on the 2 items described in Attachment A will not be issued unless the evaluations are not completed as 21.

l1 Attachment A 10 CFR 21 Deviation Evaluation Extensions Deviation Discovery Date: 5/10/91 (10/29/91)

Description:

Several deficiencies with motor operated valves were noted as follows when test data was compared with calculations:

• V826B Measured thrust exceeded calculated weak link

'hrust.

• V738B - Calculated dp thrust exceeds thrust measured. by a static test.

• V871A Measured thrust in differential pressure test exceeds calculated motor stall thrust.

Valves have been found to be acceptable for interim use until further testing or repair is performed. (NCR 91-362)

Scheduled Evaluation Completion Date: 7/15/92 Deviation Discovery Date 8/21/91 (10/29/91)

Description:

During receipt inspection, two two inch Velan manual 1500 5 ASNE Class II valves were identified with gouges. Valves are not installed in the plant. Depth and significance of gouges are being evaluated. ,(NCR 91-481)

Scheduled Evaluation Completion Date: 7/15/92 m006
