During the 2000 CDT pumping of the Drywell … During the 2000 CDT pumping of the Drywell Floor Drain Sump on 08/16/2008, the pumps failed to pump as indicated by the integrator reading zero with the pump running. The sump pump was running for approximately 2-3 minutes with the integrator showing no flow. The pump typically auto stops after approximately 30 seconds; since this did not happen, it appears to be a flow restriction and not an integrator problem. 3A DWFDS pump was started first and then 3B DWFDS pump was attempted with no flow noted for either pump.</br>Both the 3-2001-105 and -106 valves indicated OPEN.
