BROWNS FERRY NUCLEAR PLANT (BFN) UNIT 3 - TECHNICAL SPECIFICATION (TS) APPROVAL SCHEDULE TO SUPPORT UNIT 3 RESTART I
l As you requested, we are providing in this letter the schedule for approval of TS changes necessary to support Unit 3 restart. To date, we have submitted to NRC'nine of the ;
fourteen changes. We expect to submit the remaining five' within the next six months. These TS changes require NRC +
approval to support system return to service and other major plant milestones.
The enclosure to this letter provides a schedule for each major plant milestone depicting the date NRC approval is needed for each TS change. . The NRC: approval need date for each change is based on the.affected system's return'to service date and plant milestone date. The dates provided are the "early-finish" dates from the current Unit 3 restart schedule. That is, they reflect the most optimistic schedule. In probabilistic terms, they represent milestone '
dates with a 10 percent confidence level.that can be achieved. We note that each of those milestones also has a completion date with a 90 percent confidence level that'is seventeen weeks later than the "carly-finish" date. .
