Will refueling or resumption of operation thereafter require a technical specification change or other license amendment?.If answer is yes, what, in general, will.there be? If answer is no, has the reload fuel design and core configuration been reviewed by your Plant Safety Review Committee to determine whether any unreviewed safety questions are associated with the core reload (Ref. 10 CFR Section 50.59)?
Unknown at this time.
Cycle design has not-been finalized.
