1. Scheduled date for next refueling shutdown. ,

Cycle 7 refueling outage began June 5,1993. -

2. Scheduled date for restart following refueling.

Restart from Cycle 7 refueling outage is forecast for August 29, 1993.

3. Will refueling or resumption of operation thereafter require a Technical Specification change or other license amendment?

Yes.

What will these be?  ;

A change has been requested to Technical Specification 4.4.5.2.1 to allow a delay in performing an RCS inventory balance during plant transients. Although not required, NRC approval of this change is desired prior to startup from the Unit 2 Cycle 7 outage.
