2. Scheduled oste for restart following refueling.

]

Restart from Cycle < cefueling outage is forecast for April 15, 1995.

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

Yes What will these be?

A. A proposed change to the Technical Specifications has been requested which will revise the minimum water level in the refueling cavity with only one train of shutdown cooling operable.

B. A proposed change to the Technical Specifications has been requested to revise the allowed Linear Heat Rate from 13.9 to 13.0 kw/ft.

C. A proposed change to the Final Safety Analysis has been requested to remove the diversity requirement of the pressurizer pressure transmitters ,

providing input to the shutdown cooling open pennissive interlock.

D. Proposed change to the Technical Specifications (PCN 431), revising the ,

automatic reset of the low pressurizer pressure bypass, has been revised  !

to simplify the request. -
