(803) 345-4297 MARCH 1989 At the beginning of March 1989, the plant was operating at approximately 47 percent power to allow cleanup of steam generator water chemistry which was out of specification as a result of a resin intrusion event. This power level was maintained until March 10.
On March 10, at 1005 hours0.0116 days <br />0.279 hours <br />0.00166 weeks <br />3.824025e-4 months <br />, a controlled manual shutdown was initiated. The generator was taken off line at 1225 hours0.0142 days <br />0.34 hours <br />0.00203 weeks <br />4.661125e-4 months <br /> and the plant entered Mode 3 at 1205.
The shutdown was initiated primarily to allow cleanup of steam generator water chemistry which could not be accomplished at power. The steam generators were sludge lanced and the remainder of the secondary system was flushed and cleaned.
On March 29, at 2255 hours0.0261 days <br />0.626 hours <br />0.00373 weeks <br />8.580275e-4 months <br />, the reactor was taken critical. The generator was placed on line at 1732 hours0.02 days <br />0.481 hours <br />0.00286 weeks <br />6.59026e-4 months <br /> on March 30. At 1819 hours0.0211 days <br />0.505 hours <br />0.00301 weeks <br />6.921295e-4 months <br />, the turbine tripped on indicated high moisture separator / reheater level. The generator was again placed on line at 1047 hours0.0121 days <br />0.291 hours <br />0.00173 weeks <br />3.983835e-4 months <br /> on March 31.
At the end of March, the plant was at approximately 30 percent power, holding for steam generator chemistry cleanup.
