l REFUELING INFORMATION REQUEST

1. Name of Facility:

Three Mile Island Nuclear Station, Unit 1

2. Scheduled date for next refueling shutdown:

Unknown 3 Scheduled date for restart following refueling: Unknown

h. Will refueling or resumption of operation thereafter require a tecalical specification change or other license amendment?

If answer is ye5, in general, what vill these 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)? If no such review has taken place, when is it scheduled? Amendment No. 50, Cycle 5 reload, was approved on 3-16-79

                                                                                         ^^

5 Scheduled date(s) for submitting proposed licensing action and supporting infor=ation: N/A

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:

N/A , T. The number of fuel assemblies (a) in the core, and (b) in the spent fuel storage pool: (a) 177 ;7q (b) 208

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:

The present licensed capacity is 752. There are no planned increases at this time. 9 The projected date of the last refueling that can be discharged to the spent fuel pool assuming the present licensed capacity: 1986 is the last refueling discharge which allows full core off-load capacity (177 fuel assemblies).
