Title	Vacuum Pump Seal Water Supply Failure
Event Description	The air monitoring vacuum pumps were disabled for approximately 70 minutes. The soft water supply to the air monitoring vacuum pump seals on the 2nd floor of the Feed Materials Building (FMB) was shut down for annual shut down. These pumps provide vacuum for the stack monitoring and personnel area monitoring systems in the FMB. While the soft water system was shut down a sanitary well water supply was being used for the vacuum pump seals. A restriction in the sanitary water supply line interrupted the flow to the pump seals. This caused the vacuum pumps to be shut down until a temporary water supply could be established. A temporary water supply was reestablished to the pump seals. The pumps were restored to service at approximately 1030 CST on 03/02/2015. The licensee notified NRC Region II (Hickey) and will notify the state.
