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 and an exem) tion from  !

10 CFR 50 Appendix J has been requested to permit deferring tie '

Integrated Leakrate Testing.

C. 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. ,

i D. A proposed change to the Final Safety Analysis has been requested to i remove the diversity requirement of the pressurizer pressure transmitters providing input to the shutdown cooling open permissive interlock. ,

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

automatic reset of the low pressurizer pressure bypass, has been revised i to simplify the request.
