Leitz, E E

On March 19, 1960, KE Reactor was scrammed by a Panellit gauge due to a reduction in riser pressure when two high lift pumps were dropped off the process water system. Prior to the scram, KE Reactor was operating with five high lift process pumps while pump set Number 6 was being given its scheduled Class A Maintenance. Upon completion of its Class A'' pump set Number 6 was being put back on the line when arcing occurred in the 13,800 volt cubicle (due to improper contacts) causing the bus differential relay to trip and loss of electrical power to high lift pumps 4, 5, and 6.
