Design Electrical Rating (Rlwe-Net).
The nominal net electrical output of the unit specified by the utility and used for the purpose of plant design.
2 Maximum Dependable Capacity (lwe-Net)
The gross electrical ouput as measured at the output terminals of the turbine-generator during the most restrictive seasonal conditions minus the normal station service loads.
3 Number of Hours the Reactor Was Critical.
The total number of hours during the gross hours of the reporting period that the reactor was critical.
4 Number of Hours the Generator Was On LUne.
(Also called Service Hours). The total number of hours during the gross hours of the reporting period that the unit operated with breakers closed to the station bus.
The sum of the hours the gerator was on line plus the total outage hours should equal the gross hours in the reporting period.

COMMENTS 1
2/16/02 S: SCHEDULED 744.0 C, H 1.4 13 RFO work on the reactor vessel pressure retaining head revealed degradation and corrosion. As a result the head was replaced and all boric acid was removed from containment. The plant remained shutdown due to modifications of the Decay Heat Valve Pit, the Emergency Sump, Containment Air Coolers, etc. The plant is currently involved in the resolution of issues with it's High Pressure Injection Pumps along with additional work.
SUMMARY
The reactor was shutdown on February 16, 2002 to begin the 13th refueling outage. Corrosion and degradation was found on the head and it has since been replaced. The plant remained shutdown through the month of July due to continuing work.
