Cycle 5 was initiated in May 1985.
The next refueling shutdown is scheduled for June 1986.
3.
Scheduled date for restart following refueling.
August 1986 4.
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)?
' Cycle 6 details are still being reviewed.
A modified CPC program was installed in November af ter Technical Specification approval.
5.
Scheduled date(s) for submitting proposed licensing action and supporting information.
If required, submission will be by May 1986.
6.
Important licenring 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.
The fresh fuel will have a modification to the CEA guide tube wear sleeves which has been reviewed.
(Ref. SER dated September 7, 1984 for C-E Report LD-84-043).
A longer cycle and a change in in-core fuel management from out-in-in to in-in-out are also planned.
