The fire, which was in reality just smoke jroduced from the overheating of a small solenoid located in the pump speed changer switch, was extinguished by deenergizing the equipment at 0532 hours0.00616 days <br />0.148 hours <br />8.796296e-4 weeks <br />2.02426e-4 months <br />.

power.

The cause of this trip was identified to be the result of procedural inadequacies while using the new forward / reverse flush procedure on the feedwater system.

On May 28, 1983, at 0230 hours0.00266 days <br />0.0639 hours <br />3.80291e-4 weeks <br />8.7515e-5 months <br />, the reactor tripped at 72% power f rom a turbine trip due to high vibration on #9 bearing.

On May 31, 1983, Virgil C.

Summer Nuclear Station was at 74% power and power ascension testing was continuing.
