SUMMARY
- The plantbegan the month at essentiallyfull power. On 01/09/05 at 1127 hour0.013 days <br />0.313 hours <br />0.00186 weeks <br />4.288235e-4 months <br />sthe reactorwas manuallytripped dueto lowering main condenservacuum. Aleak path to the condenser was identified and repaired. On 01/14/05 at 1155 hours0.0134 days <br />0.321 hours <br />0.00191 weeks <br />4.394775e-4 months <br /> the plant achieved criticality. During turbine roll-up the turbine rotor to low pressure turbine casing differential expansion limit was reached and the turbine was manually tripped, resulting In a delay to power production. The plant was returned to service on 01/19/05 at 06:27 hours, with steady-state full power achieved on 01/21/05. The plant ended the month at essentially full power.
