REFUELING INFORMATION ,

DOCKET NO. 50-293 NAME: Pilarim i COMPLETED BY: R.L. Cannon TELEPHONE: (508)830-8321  !

REPORT MONTH June 1996 i Tha following refueling information is included in the Monthly Report as requested in an NRC letter to BECo, dit:d January 18,1978:

l For your convenience, the information supplied has been enumerated so that each number corresponds to  ;

equivalent notation utilized in the request. i

- 1. The name of this facility is Pilgrim Nuclear Power Station, Docket Number 50-293.

l

2. Scheduled date for next re'aeling shutdown: February 1,1997.

3. Scheduled date for restart following next refueling: March 14,1997.

4. Due to their similarity, requests 4, 5, & 6 are responded to collectively under #6.

t 5.' See #6.

l 6. The new fuel loaded during the 1995 refueling outage (RFO-10) is of a different design than that j loaded in the previous refueling outage and consists of 136 riew fuel assemblies. '

7. (a) There are 580 fuel assemblies in the core.

~

(b) There are 1765 fuel assemblies in the spent fuel pool.

8. (a) The station is presently licensed to store 3859 spent fuel assemblies. The spent fuel storage i i capacity is 2891 fuel assemblies. However,23 spent fuel locations cannot be used due to  !

refuel bridge limitations. ,

(b) The planned spent fuel storage capacity is 3859 fuel assemblies. l

9. With present spent fuel in storage, the spent fuel pool now has the capacity to accommodate an additional 1103 fuel assemblies.
