3 318/95-002 JC CBL1 The unit tripped on 01/13/95 at 1047 due to low Steam Generator lestl. The cause of the low S/G lestl w2s due to the Main Feedwater MOV and MSIV closing on a SGIS channel actuation. The SGIS was caused by a technician having a wire, connected to Steam Generator 1I Pressure Transmitter, break in his hands while conducting a tagging request verification walkdown, at the same time other technicians were performing a surveillance test which required a second SGIS channel to be tripped. The combination of the two tripped channels resulted in a SGIS actuation occurring and the subsequent plant trip.

An imtstigation team was immediately formed and is currently on going.

On 01/15/95 at 0246 Alting reactor startup the unit tripped due to a Reactor Protective System loss ofload signal. A power excursion from 4% to 13% occurred after steam generator lestis increased as a result of unsuccessfully operating 22 SGFP with main steam. The increase in steam generator lestis caused a cooldown of the Reactor Coolant system resulting in the power excursion. The immediate corrective action was to conduct shift briefings and added startup cmtrage.

SUMMARY

OF OPERATING EXPERIENCE lanuary 1995 The unit began the month at 100% reactor power. On 1/13/95 at 1047 the reactor tripped due to low levels in the Steam Generator following an inadvertent Steam Generator Isolation Signal (SGIS) Actuation. The SGIS actuation occurred when while Technicians were conducting a Surveillance Test, which required an SGIS actuation signal to be insened, another Technician caused a second SGIS actuation signal to occur when a wire which was canWad o 11 SG pressure transmitter, broke offin his hands while he was

)

t conducting a tagging request verification walkdown. The reactor was again taken critical at 0020 and at 0246 on 1/15/ >. + ripped on a loss ofload signal due to high S/G level while starting a Main Feedwater Pump. The ur.. wa paralleled to the grid on 1/18/95 at 1350. Reactor power was increased to 100% at 1115 on 1/19/M On 1/28/95 power was reduced to 97.5% during an STP test when a control element assembly dropped.

'Ihe element was withdrawn and the power was restored to 100% on 1/29/95 at 0115.

The unit remained at 100% through the end of the month.
