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.
