SUMMARY
OF APRIL 7, 1994 MEETING On April 7, 1994, a public meeting was held between the NRC and CECo (the licensee) to discuss CECo's approach for improving their operability assessment process. A list of attendees is enclosed (Enclosure 1). provides a chronology of the discussions.
Most of the interest was in reviewing the operability flow model (final two pages of Enclosure 2).
Particular points of discussion were: (1) the licensee's rationale for addressing equipment operability in the process before addressing equipment degradation; (2) the key role of the shift engineer in the process.
During the discussion, the NRC staff noted that revision 1 to Generic Letter 91-18, regarding the resolution of degraded and nonconforming conditions and on operability, will not have any significant changes.
The intent of the revision is to clarify those portions that, during the application of GL 91-18 may have been confusing, and to address items that were identified during the
./
GL 91-18 workshops.

June 1989 -
January 1990 -
October 1990 -
BACKGROUND CECo Operability Task Force formed Nuclear Operations Directive on "Conduct of Operations" revised Procedure for Engineering Operability Evaluations (QE-40.1) issued November 1991 -
Generic Letter 91-18 issued January 1992 -
July 1992 -
Revision to QE-40.1 issued Communications Protocol issued to strengthen Engineering/Operations interface December 1992 -
Nuclear Operations Division Reorg_anization February 1994 -
Operability Assessment Improvement Action Plan developed
DEFINITION OF ISSUES The following issues, experienced to a varying degree from site to site, form the basis for the need to improve the process:
Ownership for ultimate determination of operability not clearly established Distinction between Operability Determination (decision) and Evaluation (supporting arguments) unclear Timeliness not always commensurate with safety significance Lack of early involvement of Operations personnel Process not well linked with Integrated Reporting Program (Division-wide problem identification, reporting and resolution process)
Threshold for documentation too high Existing procedures not consistent with post reorganization conduct of business Confusion due to separate "Operations" and "Engineering" procedures
OPERABILITY ASSESSMENT IMPROVEMENT ACTION PLAN Multi-Disciplined Team Approach "World Class" Process
DISCUSSION OF REVfSED PROCESS Process flow model created to visual!ze the process Final draft of flow model developed Critical process enhancements Distinction between Determination VS. Evaluation clearly established Ownership is clear Integration with IRP early Operations involvement documentation threshold clarified formalizes confirmatory engineering evaluation for initial determination
