p Joseph M. Farley Nuclear Plant Unit 1 Narrative Summary of Operations January 1995 At 0935 on January 7,1995, with the Unit in mode I and operating at 100 percent reactor power, a ramp to 80 percent reactor power was commenced. The unit was ramped down to perform maintenance on the 1C condensate pump.
The unit was returned to 100 percent reactor power at 2105 on January 7,1995.
At 0758, on January 13,1995, with the unit in mode 1 operating at 100 percent reactor power, the reactor tripped due to a turbine trip in response to a loss of digital electro-hydraulic control (DEllC) overspeed protection. An evaluation of the DEllC system design indicated a vulnerability of the DEHC system to minor voltage transients. Modifications were performed to the DEHC system in ord:r to reduce the vulnerability to minor voltage transients.
The unit was retumed to power operation at 2203 on January 17,1995.
The following major safety-related maintenance was performed during the month:
Modifications were performed to the DEllC system in order to reduce the i
vulnerability of the DEliC system to minor voltage transients.
