ENCLOSURE 1 REVISED SUPPLEMENTAL RESPONSE TO NRC/OIE REGION II INSPECTION REPORT NOS.
50-327/86-46 AND 50-328/86-46 Because of continued NRC concerns about the Sequoyah Plant Operations Review Committee (PORC), NRC Region II management requested a meeting with Sequoyah plant management on February 26, 1987. The Region II management concerns primarily dealt with PORC quorum and composition, PORC members' personal knowledge of issues, and impact of PORC activities on the members' other duties as managers. Sequoyah Acting Plant Manager, L. M. Nobles, presented several enhancements and corrective actions during the meeting. This revised supplemental response to violation 50-327 -328/86-46-07 provides these enhancements and corrective actions as part of the violation response.
NRC had questioned if the composition and quorum of PORC was in accordance with technical specifications since it allowed multiple individuals to act as a single PORC member. For example, the Sequoyah technical specifications list the " Maintenance Supervisor" as a PORC member. Sequoyah has an Instrument, Electrical, and Mechanical Maintenance Supervisor.
Plant procedures were written to allow any one of these three supervisors to act as a PORC member, l
but only one at a time.
NRC considered that this activity increased the j
actual number of PORC members and, therefore, the PORC quorum should have been I
increased.
In order to resolve this concern, Sequoyah has defined in plant procedure SQA21 each PORC member listed ln the technical specifications as a single position within the plant organization. Sequoyah pD..
marmgement does not consider that this earlier practice had adversely impac sd the effectiveness of PORC.
NRC management expressed concerns that procedures which were routed through the informal PORC process, and not presented and discussed during the actual PORC meeting, were being voted.on without each PORC member having personal knowledge of the procedure revisions.
In order to address this concern, a requirement to provide PORC members with either a written or verbal summary of each procedure revision was evoked on February 25, 1987, and for alized in procedure AI-4 on March 10, 1987. This enhancement will provide the PORC members present at the PORC meeting the opportunity to become knowledgeable of the procedure revision. To further enhance this process, procedure revisions are requested to be scheduled, as much as possible, in advance of the PORC l
meeting.
Another concern of NRC management involves the amount of time which PORC activities require the FORC member to spend away from normal managerial activities. To redude this impact on manager's time, a list of individuals who are qualified to' review procedures and explain the changes to PORC members has been added to SQA21. These qualified individuals will prepare a wrillen 1

~
summary, or present a verbal summary, of the item before PORC for approval.
By providing additional. personnel to ' aid in procedure review, the PORC members should be provided with. additional time to perform normal duties and be personally knowledgeabl6 of the item.
As r. long-term enhancement, Sequoyah has recently submitted a technical specification change tc. provide foe a Oualified' Reviewer PORC system. This change was submitted along with final draft procedures for implementation of the new PORC proposal. This change will formalizo the concept presently being implemented and will renove the formal PORC process from routine procedure changes. The proposed PORC changes will significantly decrease the impact on l' ORC members' managerial time.
These interim changes should resolve NRC concerns of the Sequoyah POEC process and provide for incrossed confidence in PORC activities. All of the above corrective actions and enhancements (except NRC issuance of the proposed technical specification change) are in place at this time. The proposed PORC technical specification chunge sill be implemented upon NRC issuance and will be the long-term corrective action to resolve the present PORC concerns.
