PLANT OPERATIONS

SUMMARY

- MARCH 1987 i

The following is a summary of plant operations for March 1987.

On March 4, 1987 at 0520 hours0.00602 days <br />0.144 hours <br />8.597884e-4 weeks <br />1.9786e-4 months <br />, the plant load was reduced to 1

65 percent to check for tube leaks in the main condenser. At 0634 hours0.00734 days <br />0.176 hours <br />0.00105 weeks <br />2.41237e-4 months <br />..the plant reached 400 Megawatts Electric (MWE). At 1155 hours0.0134 days <br />0.321 hours <br />0.00191 weeks <br />4.394775e-4 months <br />, a routine turbine control valve test was conducted. At 2250 hours0.026 days <br />0.625 hours <br />0.00372 weeks <br />8.56125e-4 months <br />, the waterboxes had been checked, chemistry was within acceptable limits, and the plant then commenced increasing load.

The plant was returned to 100 percent power on March 5, 1987 at 0300 l

hours.

On March 14, 1987 at 1100 hours0.0127 days <br />0.306 hours <br />0.00182 weeks <br />4.1855e-4 months <br />, a load reduction to 50 percent was initiated to evaluate a low oil level and high bearing temperature condition on Number 2 reactor coolant pump.

At 1256 hours0.0145 days <br />0.349 hours <br />0.00208 weeks <br />4.77908e-4 months <br />, the plant i

reached 300 MWE.

At 1420 hours0.0164 days <br />0.394 hours <br />0.00235 weeks <br />5.4031e-4 months <br />, plant load was reduced further I

to evaluate a potential axial offset problem.

At 1425 hours0.0165 days <br />0.396 hours <br />0.00236 weeks <br />5.422125e-4 months <br />, normal l'

conditions were restored and a load commenced. At 1945 hours0.0225 days <br />0.54 hours <br />0.00322 weeks <br />7.400725e-4 months <br />, the plant was at 100 percent power.

On March 26, 1987 at 1542 hours0.0178 days <br />0.428 hours <br />0.00255 weeks <br />5.86731e-4 months <br />, the plant reached 78 Billion Kilowatt Hours generation.

On March 29, 1987 at 0220 hours0.00255 days <br />0.0611 hours <br />3.637566e-4 weeks <br />8.371e-5 months <br />, a load reduction to 50 percent was j

initiated to investigate a high valve stem leak off temperature.

Reactor Coolant System leak rate exceeded the 10 gallon per minute limit specified in Technical Specifications by approximately 2 gallons per minute.

At 0420 hours0.00486 days <br />0.117 hours <br />6.944444e-4 weeks <br />1.5981e-4 months <br />, the plant reached 300 MWE and three loop stop valves were backseated to correct the problem.

At 0810 hours0.00938 days <br />0.225 hours <br />0.00134 weeks <br />3.08205e-4 months <br />, a l

routine turbine control valve test was conducted.

At 0820 hours0.00949 days <br />0.228 hours <br />0.00136 weeks <br />3.1201e-4 months <br />, l

normal conditions were restored and the load increase commenced.

At 1238 hours0.0143 days <br />0.344 hours <br />0.00205 weeks <br />4.71059e-4 months <br />, the plant was at 100 percent power.

On March 30, 1987 at 1609 hours0.0186 days <br />0.447 hours <br />0.00266 weeks <br />6.122245e-4 months <br />, the plant reduced power to 92 percent 3

i due to a problem with a feedwater heater level control valve. At 1640

)

hours, normal conditions were restored and a load increase connenced.

At 1938 hours0.0224 days <br />0.538 hours <br />0.0032 weeks <br />7.37409e-4 months <br />, the plant was at 100 percent power.

l The plant was operated at full power for the remainder of the month.
