MONTHLY OPERATING EXPERIENCE UNIT I MARCH, 1988 March 1 The Unit remained critical, power ascension was delayed dueto steam generator secondary water chemistry.

March 2 The Unit was synchronized at 0156 hours0.00181 days <br />0.0433 hours <br />2.579365e-4 weeks <br />5.9358e-5 months <br />. At 0238 hours0.00275 days <br />0.0661 hours <br />3.935185e-4 weeks <br />9.0559e-5 months <br />, the Unit was removed from service to stabilize control of the Steam Generator Feedwater System. At 0541 hours0.00626 days <br />0.15 hours <br />8.945106e-4 weeks <br />2.058505e-4 months <br />, the Unit was synchronized and power output was increased to approximately 15% for turbine expansion measurements.

At 1400 hours0.0162 days <br />0.389 hours <br />0.00231 weeks <br />5.327e-4 months <br />, power was reduced to permit turbine overspeedtrip testing. Turbine overspeed trip testing was performed at 1436 hours0.0166 days <br />0.399 hours <br />0.00237 weeks <br />5.46398e-4 months <br />, 1444 hours0.0167 days <br />0.401 hours <br />0.00239 weeks <br />5.49442e-4 months <br /> and 1508 hours0.0175 days <br />0.419 hours <br />0.00249 weeks <br />5.73794e-4 months <br />.

At 1912 hours0.0221 days <br />0.531 hours <br />0.00316 weeks <br />7.27516e-4 months <br />, the Unit was synchronized and power was increased to approximately 30%.

March 3 The Unit remained at 30% power to permit continuation of core physics testina.

March 4 At 1715 hours0.0198 days <br />0.476 hours <br />0.00284 weeks <br />6.525575e-4 months <br />, peswer ascension was initiated. At 230$

hours, the power ascension was halted with the Unit at approximately 45% output to permit improvement to steam generator secondary water chemistry.

March 5 At 0140 hours0.00162 days <br />0.0389 hours <br />2.314815e-4 weeks <br />5.327e-5 months <br />, power ascension was initiated. At 0430 hours0.00498 days <br />0.119 hours <br />7.109788e-4 weeks <br />1.63615e-4 months <br />, the power ascension was halted with the Unit at approximately 53% output to permit data collection on the Unit's 'A' Main Feedwater Pump. At 0730 hours0.00845 days <br />0.203 hours <br />0.00121 weeks <br />2.77765e-4 months <br />, power ascension was initiated. At 1440, the power ascension was halted. The Unit was at approximately 75%

output to obtain equilibrium xenon cond.' tion for core flux mapping.

l March 6 The Unit operated at a nominal value of 75% output to l permit core flux mapping.

l l March 7 At 1600 hours0.0185 days <br />0.444 hours <br />0.00265 weeks <br />6.088e-4 months <br />, power ascension was initiated. At 2100 l hours, the power ascension was halted with the Unit at i approximately 90% output to permit power range nuclear l

instrumentation calibration.

March 8 The Unit operated at a nominal value of 90% output to l permit calibration of the reactor's power range nuclear l instrumentation.

l March 9 At 1620 hours0.0188 days <br />0.45 hours <br />0.00268 weeks <br />6.1641e-4 months <br />, power ascension was initiated. At 1925 hours0.0223 days <br />0.535 hours <br />0.00318 weeks <br />7.324625e-4 months <br />, the Unit's output was stabilized at 95% output to l permit a secondary calorimetric. Power was subsequently l increased to a nominal value of 100% output.
