For your convenience, the information supplied has been enumerated so that each number corresponds to i cquivalent notation utilized in the request.

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

d

2. Scheduled date for next refueling shutdown

February 15,1997.

j 3. Scheduled date for restart following next refueling: March 29,1997.

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

l

! 5. See #6.

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

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

i (b) There are 1973 fuel assemblies in the spent fuel pool. This includes 208 new fuel assemblies awaiting fuelloading for cycle 12.

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

e i

j (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 j additional 1103 fuel assemblies.
