Narrative Summary d Operating Experiences I

Unit 1 began the month d May at a nominal 100% d rated thermal power (RTP).

On May 7,1995, at 0021 hours2.430556e-4 days <br />0.00583 hours <br />3.472222e-5 weeks <br />7.9905e-6 months <br />, power was reduced to 90% RTP for main turbine valve testing Following testing, the Unit commenced a shutdown to perform maintenance on the 'C' drain cooler, 'A' recirculation pump seal, and the condenser waterboxes. The reactor was scrammed at 0904 hours0.0105 days <br />0.251 hours <br />0.00149 weeks <br />3.43972e-4 months <br /> on May 7,1995. On May 10,1995, the mode switch was placed in startup and control rod withdrawal commenced shortly thereafter. The unit 1 reactor went critical at 1815 l

hours and on May 11,1995, at 0541 hours0.00626 days <br />0.15 hours <br />8.945106e-4 weeks <br />2.058505e-4 months <br />, the mode switch was placed in run. The main i
