PROCESS GAUGE SHUTTER STUCK OPEN

"In the process of performing the inventory/shutter check it was reported on March 19, 2015 that our Kay Ray Model Number: 7050, Serial Number: 1405, 200 mCi, Cs-137 gauge located on 4B DTU (Deslime Thickener U/Flow) in the deslime basement had a broken handle on the shutter mechanism, rendering the shutter non-operable. Work order (1545064) was entered into Ellipse. It was determined that the area in which the gauge is located does not create an exposure hazard.

"The plant process requires the shutter to remain in the open position during normal operation and does not create a hazard to individuals, the course of action will be to remove and replace the gauge at the first opportunity. Once the gauge is removed, it will be placed and locked in the cage located in the warehouse. The gauge will be placed on top of the required amount of lead to remove any potential exposure hazard; surveys will be performed to confirm personnel safety."

AGREEMENT STATE REPORT - DAMAGED DENSITY GAUGE

The following report was received from the Washington State Department of Health via email:

"On 11/3/2018, a gauge user was working at a jobsite located in Kirkland, Washington. He sat the gauge down and moved approximately 30 feet away to speak to a contractor. While the gauge was out of his direct control, it was hit by a piece of heavy equipment and damaged. The contractor took the gauge back to the Redmond office, secured it in the gauge storage room, and notified the office ARSO [Assistant Radiation Safety Officer] and corporate RSO [Radiation Safety Officer]. The ARSO, notified DOH [Washington State Department of Health] that evening. [The Washington State Department of Health Laboratory Program Manager] spoke with [the ARSO] to get an overview of the incident.

"[The DOH Laboratory Program Manager] met with the ARSO and the corporate RSO, at the Redmond office at 0930 PST on 11/4/2018 to examine the gauge (CPN MC1DRP S/N MD00805859) to determine whether the Cs-137 and Am-241 sources had been compromised. After performing swab tests of the interior and exterior of the gauge and measuring the exposure rates around the gauge, [The DOH Laboratory Program Manager] made the assumption that the sealed sources were not compromised (the licensee couldn't do this because they don't have a survey instrument). [The DOH Laboratory Program Manager] also surveyed the vehicle used to transport the damaged gauge to verify that there was no detectable contamination in the vehicle.

"DOH will conduct an investigation into the incident, and the licensee is submitting an incident report. More information to follow."

Event Report ID: WA-18-027

* * * UPDATE AT 1229 EST ON 12/5/2018 FROM ANDREW HALLORAN TO MARK ABRAMOVITZ * * *

The following update was received via e-mail:

"DOH [Washington State Department of Health] conducted an investigation and a review of the licensee's internal incident report and root cause analysis. The gauge user did not maintain direct control of the gauge, resulting in the gauge being left unattended when it was damaged by an excavator. Additionally, the licensee failed to follow both the emergency procedures and radiation safety program guidance included in their radioactive materials license application renewal, further compounding the health and safety issues. Instead of securing the area and remaining onsite and alerting DOH as required by procedure, the gauge user and project manager decided to remove the damaged gauge and return it to the Redmond storage location. Both the failure to maintain control of the gauge and the failure to follow the emergency procedures were cited as violations in a compliance letter sent to GeoEngineers. In addition to the corrective actions required by the compliance letter, DOH will also perform a follow-up inspection of the Redmond office and field site."

This event was closed on 12/5/2018.

Notified the R4DO (Gaddy) and NMSS (via e-mail).

AGREEMENT STATE REPORT - STOLEN TROXLER MOISTURE-DENSITY GAUGE

The following information was received from the State of Florida via e-mail:

"[The Licensee Operations Manager ] called [the Florida Bureau of Radiation Control] to report a Troxler gauge theft from the truck of [an operator]. The gauge was noted missing from the back of [the operator's] truck on Sunday, November 4, 2018. The Incident was reported to this office [Florida Bureau of Radiation Control] on November 5, 2018 at 1030 EST. [The Licensee Operations Manager] plans to call local law enforcement to report the theft. At the time of this report, [the Licensee Operations Manager] could not furnish [the operator's] residential address."

The gauge contained an 8 mCi Cs-137 source and a 40 mCi Am-241/Be source.

Florida Incident Number: FL18-136


* * * UPDATE FROM MARK SEIDENSTICKER TO TOM KENDZIA AT 1050 EST ON 11/6/2018 * * *

The following information was reported via phone:

The Florida Bureau of Radiation Control was informed that the Troxler gauge has been found. They have no other information at this time.

Notified R1DO (WERKHEISER), ILTAB (via E-mail), and NMSS Events Notifications E-mail group.

THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL

Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

SPECIFIED SYSTEM ACTUATION

"On November 12, 2018, at 1636 EST, with Surry Unit 1 at 100 percent power and Surry Unit 2 defueled, the 'C' Reserve Station Service Transformer (RSST) pilot wire lockout actuated during restoration of the 'C' RSST following transformer replacement. This resulted in electrical isolation of the 'C' RSST, the 'F' Transfer Bus, the Unit 1 'H' Emergency Bus, and the Unit 2 'J' Emergency Bus. The #1 and #3 Emergency Diesel Generators automatically started and loaded onto the 1H and 2J emergency buses, respectively, as designed. Operations entered the appropriate abnormal procedures and stabilized both units. This equipment operated as expected during the event.

"The Surry electrical distribution system was in an off-normal alignment to support 'C' RSST replacement with the dependable alternate power supply from Unit 2 station service backfeed supplying the 1H and 2J emergency buses. The 'C' RSST pilot wire lockout tripped and locked out the station service supply tie breaker to the 'F' Transfer Bus.

"The organization is reviewing the 'C' RSST pilot wire lockout and the required actions for recovery. Surry Unit 1 entered a 6-hour action statement to place the unit in Hot Shutdown due to this partial loss of offsite power. This clock was exited upon reset of the pilot wire lockout, restoring backfeed as a dependable offsite power source. Unit 1 remained at 100 percent power throughout the event.

"No radiological consequences resulted from this event. This event is being reported pursuant to 10 CFR 50.72(b)(3)(iv)(A) due to actuation of the #1 and #3 Emergency Diesel Generators.

"The NRC Resident was notified."
