NARRATIVE

SUMMARY

-MONTH: February 1995 Catawba Unit 2 began the month of February operating at 100% full-power. On02/21/95 at:2154-the unit experienced a reactor / turbine trip due to closure of steam' generator

'B' main steam isolation valve caused by a bad optical isolator. On 02/23/95 at 0030 a condenser cooling water leak became critical path until 02/25/95

at 2345, when the closure of steam generator

'B' main steam isolation valve resumed as critical path. The unit did not return to service during the month of February, 1995.
