SUMMARY

OF OPERATING EXPERIENCE

- MONTH: MARCH 1997 For March, Unit 2 continued with the refueling outage that started on Jan. 25th. The outage was extended due to two items:

1. An unreviewed safety question conceming the cooling water emergency intake line.

2. Two issues conceming Aux Feedwater:

I LA. Aux Feedwater operability with regards to a loss of FW ATWS event.

B. Aux Feedwater Pump runout protection (LER 1-96-010).

The outage ended on Sunday March 30 @ 0005 when the generator went on-line. The unit is limited to less than 40% of reactor power due to the AFW/FW ATWS issue.

Spent Fuel Pool Update:

Fuel assemblies in each core - 121 -

Fuel assemblies in the spent fuel pool consolidate - 18 unconsolidated 1157 Licensed spent fuel pool storage capacity - 1386 Fuel assemblies in Dry Cask Storage - 280 B
