Dock:;t No. 50-352 AttIchmsnt to Monthly Operating Report for February 1998 Limerick Generating Station Unit 1 February 1 through February 28,1998 1.

Narrative Summarv of Operatina Exoeriences Unit 1 began the month of February 1998 at 0% of rated thermal power (RTP) while performing a planned maintenance outage to repair the HPCI exhaust valve and address an increase in unidentifiexf drywellileakage.

On February 4,1998 at 0213 hours0.00247 days <br />0.0592 hours <br />3.521825e-4 weeks <br />8.10465e-5 months <br />, the reactor mode switch was placed in start up.

On February 5,1998 at 1221 hours0.0141 days <br />0.339 hours <br />0.00202 weeks <br />4.645905e-4 months <br />, the reactor was scrammed to perform repairs on the HPCI pump discharge valve.

1 On February 7,1998 at 0858 hours0.00993 days <br />0.238 hours <br />0.00142 weeks <br />3.26469e-4 months <br />, the reactor mode switch was placed in start up.

On February 7,1998 at 1320 hours0.0153 days <br />0.367 hours <br />0.00218 weeks <br />5.0226e-4 months <br />, the reactor was critical.

On February 10,1998 at 0110 hours0.00127 days <br />0.0306 hours <br />1.818783e-4 weeks <br />4.1855e-5 months <br />, the main turbine generator was synchronized to the grid.

On February 11,1998 at 0422 hours0.00488 days <br />0.117 hours <br />6.977513e-4 weeks <br />1.60571e-4 months <br />, power was restored to 100% of RTP.

On February 11,1998 at 1740 hours0.0201 days <br />0.483 hours <br />0.00288 weeks <br />6.6207e-4 months <br />, power was reduced to 75% of RTP due to low differential pressure on the #2 Jet pump.

On February 14,1998 at 2300 hours0.0266 days <br />0.639 hours <br />0.0038 weeks <br />8.7515e-4 months <br />, power was reduced to 65% of RTP for a control rod pattem adjustment.

On February 15,1998 at 0825 hours0.00955 days <br />0.229 hours <br />0.00136 weeks <br />3.139125e-4 months <br />, power was increased to 88% of RTP. The 6*

stage feedwater heaters were taken out of service. Power was further increased to 97% RTP at 2327 hours0.0269 days <br />0.646 hours <br />0.00385 weeks <br />8.854235e-4 months <br />, maintaining the required difference between the #1 and #2 jet pumps.

On February 23,1998 at 2311 hours0.0267 days <br />0.642 hours <br />0.00382 weeks <br />8.793355e-4 months <br />, power was decreased by 5% of RTP for the removal of the 5* stage feedwater heaters from service. Power was retumed to 94% of RTP by February 24,1998 at 0300 hours0.00347 days <br />0.0833 hours <br />4.960317e-4 weeks <br />1.1415e-4 months <br />.

Unit 1 ended this month operating at 94% RTP due to the end of cycle coast j

down and the #2 jet pump problems.
