Name of facility: Arkansas Nuclear One - Unit 2 2.
Scheduled date for next refueling shutdown.
January 1988 3.
Scheduled date for restart following refueling. March 1988 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)?
No.
However, reload fuel design is in the planning stage.
5.
Scheduled date(s) for submitting proposed licensing action and supporting information.
If required, Technical Specification change requests will be submitted before December 1987.
6.
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.
None are expected.
7.
