The following was received from the State of Louisiana via email:
"On October 22, 2018 around 1000 CDT, Capitol Ultrasonics, L.L.C. was working at Exxon Refinery. Two industrial radiographers' pocket ion chambers went off scale while moving the source guide tube. Dose reconstruction indicated 743 mR whole body to one radiographer. The second radiographer received 294 mR whole body and 51 Rem extremity dose to the hands.
"The industrial radiography camera being used was an 880D Amersham, serial number: D15404, with a source strength of 34.3 Ci of Ir-192, serial number: 66839G.
"Body badges are being sent in for immediate processing at this time."

AGREEMENT STATE REPORT - DAMAGED MOISTURE DENSITY GAUGE
The following was received from the Commonwealth of Virginia by email:
"On October 22, 2018, the RSO [Radiation Safety Officer] for the licensee reported an accident that morning at a construction site near Sterling, Virginia. A roller hit a portable moisture/density gauge with its rear wheels while backing up. The gauge user established an exclusionary area until the RSO arrived to perform an onsite investigation and radiation survey. The RSO reported the plastic housing of the gauge was cracked but the source rod and shielding were intact. Surveys indicated no unusual radiation levels. The licensee contacted a vendor to analyze leak test samples and to determine potential repairs to the gauge.
"The gauge was a Troxler 3430, serial [number] 30198, with an 8 milliCurie Cs-137 source, serial [number] 750-2497, and a 40 milliCurie Am-241:Be source, serial [number] 47-27175."

INOPERABLE CONTROL ROOM ENVELOPE DUE TO FAILED SURVEILLANCE
"On October 22, 2018 at 2241 hrs. EDT, a loss of Control Room Envelope (CRE) was declared due to failing to meet the requirements of (surveillance requirement) SR 4.7.6.1h during 72-month surveillance testing. Measured in-leakage exceeded the SR acceptance value.
"Abnormal Operating Procedure 2588A, 'Mitigating Actions for Control Room Envelope Boundary Breach', have been implemented."
The licensee has notified Connecticut Department of Environmental Protection, Connecticut dispatch, Waterford dispatch, and the NRC Resident Inspector of this event.

AGREEMENT STATE REPORT - STUCK SHUTTER
The following was received from the State of Texas by email:
"On October 23, 2018, [a report was received by the Texas Department of State Health Services that] a consulting company servicing the equipment for a licensee found during a maintenance operation that a gauge had a stuck shutter on October 22, 2018. The device is labeled Vega, SH-F1A, 20 mCi, Cesium-137, Source Serial number 5786CN. The gauge measures vessel material levels and is mounted about 10 feet above ground level. No risk of radiation exposure to members of the public or radiation workers at the location. The gauge shutter is stuck in the open operating position. A repair company was called to contract an inspection to repair or replace the gauge. An update will be provided as information is obtained."

CONTROL ROOM ENVELOPE DECLARED INOPERABLE DUE TO DOOR LATCH FAILURE
"At 0856 EDT on October 22, 2018, it was discovered that the Control Room Envelope, a single-train system, was inoperable due to failure of a boundary door to latch; therefore, this condition is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(v)(D) as a loss of safety function. The door latch was repaired, and the Control Room Envelope declared operable at 0910 EDT.
"There was no impact on the health and safety of the public or plant personnel, as the door was capable of being closed at all times and the door was manned the entire time it could not latch.
"The NRC Resident Inspector has been notified."

"Retraction of Event #53685, Control Room Envelope Declared Inoperable due to Door Latch Failure
"Based on subsequent field measurements taken for the boundary door, the force needed to open the unlatched door is sufficient to maintain the Control Room Envelope positive pressure. Therefore, the Control Room Envelope remained Operable with the boundary door unlatched, and this issue did not prevent the system from fulfilling its safety function to mitigate the consequences of an accident.
"The NRC Resident Inspector has been notified."
Notified the R3DO (Hanna).
