Attachment 2 INSPECTION FINDINGS EVALUATION MATRIX The following pages summarize the results of the detailed evaluation of the inspection findings performed by our interdisciplinary task force prior to and subsequent to the May 21, 1986 meeting at Region III. For each modification package reviewed during the inspection, the task force addressed each deficiency as characterized by the inspection team throughout the inspection and at the interim debriefing on May 7, 1986.

The review addressed whether CECO. agrees with each finding as described by the inspectors, the safety significance of each finding, and short term and long teen corrective actions. The descriptions below provide additional background on the meaning of each column heading as intended by the task force participants.

NRC Issue - This column reflects the specific findings or deficiencies identified by the inspection team for each modification. The description of each deficiency represents the findings as characterized by the inspection teen members and communicated to our staff.

CECO. Agreement - This column indicates whether Commonwealth Edison agrees with each deficiency as characterized by the inspection team. In some cases, agreement is indicated on the basis that we concur that a deficiency exists with regard to the specific finding although we may not agree with the manner in which it was characterized. These conclusions represent the collective opinion of the inter-disciplinary task force based on discussions with plant personnel involved in the inspections and a review of the documentation associated with each mod package.

Safety Significance - This column represents the actual immediate safety significance of each individual finding in the judgement of the task force members. These conclusions are based on the accuracy of the findings as described by the inspection team, consideration of subsequent testing or documentation reviews that had not yet been performed and engineering evaluations of discrepancies. Note that this column reflects our perception of the immediate safety significance on an item-by-item basis and is not intended to reflect a collective review of the findings.

1329b l

l

Cp. erective Actions - The short term corrective actions reflect actions currently completed or in progress to resolve specific deficiencies. Long term corrective actions are indicated for some items. In many cases, identification of long term actions has been deferred pending completion of our task force investigations.

NRC Concern - This column reflects the more general areas of concern into which we believe the individual findings would be grouped by the inspection team.
