AGREEMENT STATE REPORT - THREE GAUGES WITH STUCK SHUTTERS

The following information was received from the State of Texas via email:

"On September 12, 2017, the Agency [Texas Department of State Health Services] was notified by the licensee's radiation safety officer (RSO) that during routine inspections, three Berthold nuclear gauges were found with shutters stuck in the open position. Two of the gauges were model LB7442D each containing a 30 millicurie (original activity) cesium-137 source and one was a model LB300L containing a 44.7 millicurie (original activity) cobalt-60 source.

"The shutter on the model LB300L gauge was stuck in the open position. The lock on the shutter on one of the model LB7442D gauge could not be removed. The locking latch on the other model LB7442D gauge would not operate. The RSO stated a service company has been contacted to repair the gauges and is expected to be on site by September 15, 2017. No individual will receive significant exposure to radiation due to this event."

CONTROL ROOM ENVELOPE NOT MAINTAINED

"At 1724 [CDT] on 9/18/17 during Control Room Ventilation testing Door-61, South Control Room Door, became wedged against its door stop and stuck open. Door-61 is a credited High Energy Line Break (HELB) / Fire / Flood Barrier in addition to its function to maintain the Control Room envelope. The door stop was subsequently unbolted from the floor and the door was free to close. Door-61, South Control Room Door, has since been inspected, and at 1750 [CDT], was declared functional as a HELB / Fire / Flood Barrier and Operational for purposes of maintaining the Control Room Envelope. During the 26 minutes the door was stuck open, the Control Room was in an unanalyzed condition with regards to protection from a High Energy Line Break."

The licensee notified the NRC Resident Inspector.
