The RCS level was being maintained below the top of the hot leg for removal of the Steam Generator (SG) primary manways and installation of nozzle dams. At the completion of SG nozzle dam installation RCS fill was started in accordance with 2D2, "RCS Reduced Inventory Operation," to return RCS level to 1 foot below the Reactor Vessel Flange to bring the RCS out of the reduced inventory condition. While filling the RCS, water started coming out of 22 SG cold leg manway. The control room was immediately contacted when discovered. The control room operators stopped filling the RCS and opened the RCS drain valves per 2D2 to lower the RCS level. The RCS level was lowered until water stopped coming out of the SG manway. Containment workers also started a Randolph pump to pump water out of the SG channel head to minimize the water spilling out of the manway while the RCS level was being lowered.
Lessons Learned: Causes were determined to be inadequate procedures and Insufficient hands-on training. Stop When Unsurel Safety Snippet Is there an obstruction in your way that might not stay?
OE1 3857 May 2002, Fort Calhoun -While moving the reactor vessel head assembly during a refueling outage, the control pendant for the polar crane caught a handrail vertical support pipe, lifting the pipe out of its mount and causing it to fall 20 ft to the walkway below. Individuals were in the area at the time, but not injured. A review indicated the pendant caught on nearby equipment many times during past refueling outages and corrective actions were not put in place. Are there any items were our equipment gets caught during moves that we have not resolved?
