Docket No. 50-352 Attachment to Monthly Operating Report for March 2002 Limerick Generating Station Unit 1 March 1 through March 31, 2002 Narrative Summary of Operatinq Experience Unit 1 began the month of March 2002 at 86% of rated thermal power (RTP) in end-of cycle coastdown.
Throughout the month, unless specified below, when the unit operated at less than 100% RTP, it was due to end-of-cycle coastdown, 1 R09 refuel outage, or post 1 R09 power ascension.
On March 4th at 1000 hours0.0116 days <br />0.278 hours <br />0.00165 weeks <br />3.805e-4 months <br />, reactor power was reduced in preparation for the 1R09 refuel outage. At 1249 hours0.0145 days <br />0.347 hours <br />0.00207 weeks <br />4.752445e-4 months <br />, the turbine was manually tripped due to high vibration during 1R09 shutdown. At 1503 hours0.0174 days <br />0.418 hours <br />0.00249 weeks <br />5.718915e-4 months <br />, the reactor was manually scrammed, from 24%
RTP to begin refueling outage 1 R09.
On March 19 th at 1734 hours0.0201 days <br />0.482 hours <br />0.00287 weeks <br />6.59787e-4 months <br />, reactor criticality was achieved.
On March 21st at 1838 hours0.0213 days <br />0.511 hours <br />0.00304 weeks <br />6.99359e-4 months <br />, the main generator was synchronized to the grid at 18%
RTP. At 1948 hours0.0225 days <br />0.541 hours <br />0.00322 weeks <br />7.41214e-4 months <br />, the main generator was tripped for voltage regulator testing. At 2147 hours0.0248 days <br />0.596 hours <br />0.00355 weeks <br />8.169335e-4 months <br />, the main generator was again synchronized to the grid at 18% RTP.
On March 2 3 th at 0912 hours0.0106 days <br />0.253 hours <br />0.00151 weeks <br />3.47016e-4 months <br />, during power ascension, reactor power was reduced from 62% to 30% RTP to support maintenance to the 1C condensate pump. On March 25 h at 0337 hoLrs, power ascension was reestablished.
On March 2 7 th at 2100 hours0.0243 days <br />0.583 hours <br />0.00347 weeks <br />7.9905e-4 months <br />, reactor power was restored to 100% RTP.
Unit 1 ended the month of March 2002 at 100% RTP.
