SEQUOYAH NUCLRAR PLANT (SQN) UNIT 1 - RESPONSE TO QUESTION FROM AUGUST 4, 1988 COMMISSION MEETING During the course of the August 4,1988 meeting, TVA agreed to provide a response to a question asked by Commissioner Rogers on unit I restart work status. Based on our review of pages 32 and 33 of the transcript from the August 4,1988 meeting, we believe Commissioner Kenneth Rogers's question can be surnarized as follows:
Are any of the items scheduled to be complete by the end of the first unit 2 refueling outage not being done on unit 1 before restart?
In order to respond to this general question, the unit 2 cycle 3 (U2C3) refueling outage commitments in TVA's corporate commitment tracking system were reviewed against the unit I restart commitments, particular emphasis was placed on the programmatic commitments. Work common to both units was not considered because it would be scheduled for completion for both units at the same time. Based on our review, there are three specific programmatic areas scheduled for the U2C3 refueling outage that will not be completed by restart of unit 1.
They are:
1.
The Reactor Vessel Level Indication System (RVLIS) has been installed on both units. The performance of the RVLIS is currently being evaluated on unit 2.
Based on this evalu3 tion, final emergency procedures will be revised for both units to fully integrate RVLIS before startup from the U2C3 refue1 Lng outage.
2.
Inspections for vertical condult runs outside containment will be conducted during the first refueling outage after restart of each unit (unit I cycle A and U2C3 refueling outages). The inside containment inspections have been completed for both units to ensure that the testing performed for unit 2 restart is bounding.
3.
The 40-year qualification testing of silicone rubber cables for both units is scheduled to be completed before startup from the U203 refueling outage. Qualification testing for silicono rubber cables had been previously performed for a 10-y1ar qualified life to support restart of units 1 and 2.

- u.S. Nuclear Regulatory Commission 88 02 M It should be noted that the hanger work, mentioned by S. A. White in responding to Commissioner Rogers's question during the meeting, is scheduled for thrs second refueling outage after restart of unit 2.
This same work is scheduled for the first refueling outage after restart of unLL 1.
Because the first unit i refueling outage is scheduled to begin before the second unit 2 refueling outage, the unit 1 work will be completed before the unit 2 work.
