50-309 UNIT Maine Yankee DATE 800411 COMPLETED BY F. C. Beers TELEPHONE 617-366-9011 X2215 REPORT MONTH March 1980 SUSNARY OF OPEPATING EXPERIENCES At the beginning of the month, the plant was in the Refueling Shutdown mode completing the Cycle 4/5 refueling. On 3/7/80 plant heatup commenced and on the following day was stabilized at normal operating temperature and pressure.

The reactor was taken critical at 1310 hours0.0152 days <br />0.364 hours <br />0.00217 weeks <br />4.98455e-4 months <br /> on 3/9/80 and Low Power Physics

• Testing commenced.

By 1610 hours0.0186 days <br />0.447 hours <br />0.00266 weeks <br />6.12605e-4 months <br /> on 3/10/80 LPPT was complete and cleanup of the condensate, feed-water and steam generators commenced. The cleanup was considered satisfactory by 3/14/80 and the unit was phased to the grid at 2354 hours0.0272 days <br />0.654 hours <br />0.00389 weeks <br />8.95697e-4 months <br /> that day. During the next 3 days the unit had to be taken off the grid on 4 occasions to add balance weights to the turbine / generator shaft.

On 3/17/80 the unit was finally balanced and power was raised to 448.3 to per-form additional Physics Testing.

By 3/23/80 power had been raised to N76%, but due to increasing Cl concentra-i tions in the steam generators from condenser tube-to-tube sheet leaks, plus the need to change out the oil in the P-2B feed pump, a load reduction to 55% was performed. On 3/25/80 power escalation again commenced.

Because the steam generators had been subjected to prolonged exposure to elevated chloride concentrations, it was deemed prudent to drop load down to about 20%

to help leach out any residual chlorides which may have been hiding out in the steam generators. On 3/29/80 a load reduction was commenced and a steam generator chloride soak was performed.

Following the chloride soak, power escalation commenced on 3/30/80. At the end of the month power level was s92% with a slow (1% per shift) escalation to full load still in progress.
