Areas Discussed i
Mr. Paperiello stated that the purpose of the enforcement conference was
to emphasize the seriousness of the violations, and to look to the future to ensure that the root causes of these violations were identified and that sufficient attention was placed on all quality programs as well as l
correcting the maintenance and modification programs to ensure that these
'
types of violations would not occur in the future.
Mr. Phillips then presented a brief description of the violations that were identified by categorizing them into the four Appendix B Criteria of 10 CFR Part 50 which were not adequately implemented. Attachment 1 is a copy of the overheads which were used to make this presentation.
The licensee presented a detailed review of the corrective actions that i
l had been initiated subsequent to the inspection, as well as their assessment of root cause and corrective actions for the future. The
.
handouts used for this presentation are included as Attachment 2 to this report. The licensee stated that the violations identified were accurate
'
and were caused primarily by the change in status from being a construction
!
site to an operational site; however, there was disagreement on the safety significance of the event, with the licensee representatives stating that the safety significance was minimal because hardware problems would have surfaced during startup or preoperational testing of the systems, rather than when the components were called upon to perform a safety function.
.
'
Although not specifically addressed in the licensee's handouts, licensee
,
representatives indicated that a lot of training on the conduct of 10 CFR
!
l 50.59 reviews was being conducted to improve the level of these reviews.

Licensee representatives stated that they felt escalated enforcement action would be unnecessary, since the NRC had already gotten the licensee's attention regarding the problems in the maintenance and modification areas.
The enforcement conference concluded with the NRC stressing the importance of the licensee's quality assurance program to be involved in reviewing programs to find deficiencies, and the licensee representatives stating the intent to correct the problems identified and to have a top rate maintenance program.
