x REFUELING INFORMATION FOR HATCH UNIT 1 Hatch Unit 1 is scheduled to shutdown on 4-2-82, for its next refueling outage.
Startup from that outage is scheduled for 8-20-82.
Description of operation after refueling will require a
Technical Specification change concerning core thermal hydraulic limits.
No particular date for submitting proposed licensing action and supporting information has been named.
- However, the latest date for submittal will be 5-20-82.
There are 560 fuel assemblies in the core and none presently in the spent fuel storage pool.
The present licensed spent fuel pool storage capacity is 3021 fuel assemblies.
No requests for an increase in licensed storage capacity are anticipated in the near future.
The projected date of the last refueling that can be discharged to the spent fuel pool assuming the present licensed capacity is 1996.
