SlMORY OF OPERATIN3 EXPERIENCE

% e unit began the month operating at approximately 96 percent power due to

[

a tube leak on the number "2B" low-pressure feedwater heater. On March 02, j

1990, at 1218 hours0.0141 days <br />0.338 hours <br />0.00201 weeks <br />4.63449e-4 months <br />,- the unit began to gradually decrease power due to fuel limitations (a " fuel coastdown") at a rate of approximately one percent par.

day. On March 08, 1990, at 2100 hours0.0243 days <br />0.583 hours <br />0.00347 weeks <br />7.9905e-4 months <br />, the unit began a normal shutdown for refueling fran approximately 90 percent power. h e. refueling outage began at 0027 hours3.125e-4 days <br />0.0075 hours <br />4.464286e-5 weeks <br />1.02735e-5 months <br /> on March 09, 1990, when the generator output breaker was opened. %e unit remained shutdown for refueling for the remainder of the month.
