on 9/2/90, Control room operators observed a slow unexplained increase in i Reactor Vessel water-level. Operators took manual control of the feedwater-Control System attempting to restore water level to normal, When it was !
determined that feedwater Control could not be reestablished, power was 'l reduced to 60 percent and the reactor was manually scrammed at 2233 hours0.0258 days <br />0.62 hours <br />0.00369 weeks <br />8.496565e-4 months <br /> by i placing the Mode Switch in Shutdown. After the shutdown, other equipment problems were experienced-with RCIC, HPCI and RHRS.
