SUMMARY

The Unit operated at 100% power for 694 out of 744 hours0.00861 days <br />0.207 hours <br />0.00123 weeks <br />2.83092e-4 months <br /> this month. ISO-NE requested several load reductions to below 1200 MWe-Net (2-3% RTP). The Unit returned to full power operation following each with the exception of 'he first of two load reductions on 03/10. Operations reduced load and stabilized the Unit at 1205 MWe-Net (1-2% RTP) following an unexpected response during Quarterly Turbine Valve testing The unit also operated with one of its three CW pumps removed from service (97 hours0.00112 days <br />0.0269 hours <br />1.603836e-4 weeks <br />3.69085e-5 months <br />) for planned maintenance.

Net generation incr3ase to 1223 MWe during this interval because of the decrease in Station Service Load. This yielded an availability factor of 100% and a capacity factor of 99.94% based on the MDC value of 1221.0 Net MWe.I 2 Reason: A Equipment Failure (Explain)B Maintenance or Test C Refueling D Regulatory Restriction E Operator Training & License Examination F Administration G Operational Error (Explain)H Other (Explain)Method: I Manual 2 -Manual Trip/Scram 3 Automatic Trip/Scram 4 Continuation 5 Other (Explain)Page 1 of 1
