INADVERTENT UNDERVOLTAGE CONDITION INITATED DIESEL LOAD SEQUENCER, ETC. DIESEL DID NOT START.

"At approximately 1334, during realignment from monthly surveillance testing of the normal and alternate power
supply breakers to the 10 A404 vital 4 Kv bus, an inadvertent undervoltage condition appears to have occurred.
This condition resulted in initiation of the diesel load sequencer and tripping of the normal loads supplied by this
bus. The undervoltage condition was momentary in nature, the load sequencer stopped upon restoration of voltage
prior to starting the emergency diesel generator and operators successfully restarted the equipment that had tripped
and restored the load sequencer. The D Emergency Diesel Generator is considered to be operable at this time.

"The cause of the occurrence is under investigation. The plant is stable in Operational Condition 1 at 100% power.

"This event is being reported in accordance with 10CFR50.72(b)(3)(iv)(A) 'Any event or condition that results in
valid actuation of any of the systems listed in paragraph (b)(3)(iv)(B) subsection 8', specifically in this case,
Emergency ac electrical power systems." LAC Township notified by licensee.
