Name of facility: Arkansas Nuclear One - Unit 2 2.
Scheduled date for next refueling shutdown. March 15, 1985 3.
Scheduled date for restart following refueling.
May 1985 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-th_ere 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)?
Planned software changes to Core Protection' Calculators have been l
submitted for review.
Technical Specification changes associated with these changes have been submitted for NRC review.
The Reload report is now under review to determine if there are any unreviewed safety t
questions associated with the core reload.
5.
Scheduled date(s) for submitting proposed licensing action and supporting information.
By March 1985 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.
Burnable poison rods will be used in reload fuel.
7.
The number of fuel assemblies (a) in the core and (b) in the spent fuel storage pool, a) 177 b) 168 8.
The present licensed spent fuel pool storage capacity and the size of I
any increase in licensed storage capacity that has been requested or is planned, in number of fuel assemblies.
