COMPLETED BY: J. L. Darlino TELEPHONE: (714) 368-6223 MONTH: May 1993 i

1. Scheduled date for next refueling shutdown.

Cycle 7 refueling outage is forecast for June 5,1993.

2. Scheduled date for restart following refueling.

Restart from Cycle 7 refueling outage is forecast for August 1903.

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

Yes. -

What will these be?

The following Technical Specification change is desired in support "

of work being performed during the Unit 2 Cycle 7 refueling outage.

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.

4. Scheduled date for submitting proposed licensing action and supporting information.

l Proposed Change on RCS Leakrate was submitted November 20, 1992.

5. Important licensing considerations associated with refueling, e.g. new or different fuel design or supplier, unreviewed design or performance analysis ,

methods, significant changes in fuel design, new operating procedures.  ;
