Reporting Period: February 1995 REFUELING INFORMATION 1.
Name of facility: Arkansas Nuclear One - Unit 1 2.
Scheduled date for next refueling shutdown:. Entered refueling outane IR12 on February 14.1995 3.
Scheduled date for restart following refueling: Aoril 7.1995 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.10CFR Section 50.59)?
Technical Specification change to relocate additional cycle soccific parameters to the Core Operatina Limits Reoort (COLR).
5.
Scheduled date(s) for submitting proposed licensing action and supporting information:
Ibitchanne was submitted August 30.1994.
6.
Important licensing considerations associated with refueling, e.g., new or different fuel design or supplier, unreviewed design or performance analysis methods, significant clumges in fuel design, new operating procedures.
None planned 7.
The number of fuel assemblies (a) in the core and (b) in the spent fuel storage pool:
a)J12 b)2341 NOTE: The core was off-loaded on February 26,1995 for refueling outage IR12. The number of fuel assemblies in the core changed to 0 and the number in the spent fuel storage poolincreased to 922.
8.
The present licensed spent fuel pool storage capacity and the size of any increase in licensed storage capacity that has been requested or is planned, in number of fuel assemblies:
