Name of facility:
Millstone 2 2.
Scheduled date for next refueling shutdown:
Currently.in end of cycle 7 refueling / maintenance outage.
3.
Schedule date for restart following refueling: December 1986 4.
Will refueling or resumption of operation thereafter require a technical specification change or other license amendment?
N_g 5.
Scheduled date(s) for submitting licensing action and supporting information:
Two Technical Specification change requests related to the Reactor Coolant System Flow Rate were submitted on October 24, 1986 and October 27, 1986. The Technical Specification change request to revise 10CFR50, Appendix G. Heat Up and Cooldown Curves, was submitted on October 20, 1986.
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 7.
The number of fuel assemblies (a) in the core and (b) in the spent fuel storage pool:
(a) In Core:
217 (b) 512 8.
The present licensed spent fuel pool storage capacity and the size of any increase in licensed storage capacity that has been requested i
or is planned, in number of fuel assemblies:
Currently 1112 The 1112 available locations reflects the re-racked Spent Fuel Pool.
The re-racking of the Unit 2 Spent Fuel Pool has been completed.
9.
The projected date of the last refueling that can be discharged to the spent fuel pool assuming the present licensed capacity:
l 1994, Spent Fuel Pool, Fuel Core off load capacity is reached.
1998, Core Full, Spent Fuel Pool.
These numbers are based on the recently re-racked Spent Fuel Pool.
