AGREEMENT STATE REPORT - LEAKING BARRELS CONTAINING RADIOACTIVE MATERIAL

The following report was received from the State of Utah via email:

"DWMRC [Division of Waste Management and Radiation Control] was notified of the event at about 1500 MST, on January 12, 2017. The licensee indicated that the shipper, Honeywell (Converdyne) had notified the NRC and the US DOT. This incident report is the initial notification of the NRC Operations Center from the DWMRC.

"The following description is the initial information received by DWMRC. The information will be updated as the Division obtains more information.

"A van carrying [three] barrels of [solid and wet] radioactive materials was received at the White Mesa Mill. When the employees were unloading the van they realized that a barrel, maybe two, had rusted bottoms and was leaking. Although the bottom of the barrels were not rusted through, they were characterized as 'being soft'. The barrels were on plastic sheeting that should have restricted the leaking materials to the plastic; however, when the barrels were unloaded, the employees noted that there was a hole in the sheeting. When the RSO was informed of the incident and arrived at the van, he noted that there was visible leakage on the girders and the siding of the van. Unfortunately, he was unable to take measurements of the area where the leak occurred to determine the radiation levels. The RSO [Radiation Safety Officer] stated that the van had been pulled in and cleaned prior to any measurements being taken, so the only measurements were taken after the van was cleaned."

* * * UPDATE FROM GWYN GALLOWAY TO JOHN SHOEMAKER, VIA EMAIL, AT 1830 EST ON 1/13/17 * * *

"On January 12, 2017, at approximately 1142 MST, a TAM International van carrying barrels of KOH alternate feed materials from Honeywell International arrived at the White Mesa Mill Scale house. According to Honeywell the materials are basically uranium ore concentrates. The White Mesa employees began unloading the van, but as they began offloading some of the last barrels, they noticed that some of the barrels were leaking. From what they could tell, three barrels were potentially leaking . The barrels were not rusted through, but were 'soft' and allowed liquid contained in the solid materials to leak from the barrel. The material leaked from the barrel onto a plastic sheet; however, the plastic sheet had an opening (rip, tear) through which the material was able to pass. The RSO [Radiation Safety Officer] was notified of the event at about 1300 MST.

"When the RSO reached the van, the employees had completed emptying the van and had 'cleaned' the van. The RSO indicated he was able to see visible evidence that the material had been able to leak from the van, but the area had been cleaned and no valid measurements or samples of the materials leaked from the van were able to be taken. Pictures were taken and from the pictures provided to the Division [Utah Division of Waste Management and Radiation Control], it appears that only a small quantity of liquid material was leaking from the barrels. Because the contents of the barrels are primarily solid and only contain small amounts of liquid and the liquid contents in the barrels were leaking through the bottom of the barrel, through a plastic sheet, across the van floor and out of the van along a girder and the siding, it is likely that only small quantities of materials were leaking from the van. The weather across the nation has been fairly stormy this past week and has included both rain and snow. Because of the rain and snow that has been occurring while the vehicle was traveling to the Mill site, it is likely that any small amounts of materials that leaked from the van were subsequently washed away and diluted. The Mill analyzes each alternate feed stream annually to verify the isotopic content of the alternate feed. At the last verification, the Honeywell KOH material contained, approximately 633,000 mg/kg uranium (about 61% uranium), 39 pCi/g Pb-210, 44.6 pCi/g Ra-226, 358 pCi/g Th-230, and 27 pCi/g Th-232."

This event was also reported by National Response Center to the Nuclear Regulatory Commission , Report # 1168447, on 01/12/17 at 1720 EST.

AGREEMENT STATE REPORT - DENSITY GAUGE WITH STUCK OPEN SHUTTER

The following report was received from the State of Louisiana via email:

"Event type: Level density gauge on a process had a shutter malfunction. Eagle was performing their annual operational checks when the malfunction was discovered. The malfunction is the gauge shutter is stuck in the open position on an active process. The gauge Service Company, BBP Sales will make the repair or replacement after the assessment of the device. They discovered the shutters would not close. The Gauge is a RONAN SA1-C-10 device/source holder, S/N 9527GG, loaded with a 200 mCi Cs-137 source.

"Notifications: LDEQ [Louisiana Department of Environmental Control] was notified by Eagle US 2 in a message on the voice mail system on 1/10/2017. The notice was sent to the Compliance Radiation Assessment Section of LDEQ. The notification was readdressed when Eagle was contacted on 1/12/2017, to get the preliminary information report. Eagle US 2 will send LDEQ a corrective action and a final report no later than 30 days of the corrective action. The Eagle US 2 preliminary written report was received 1/12/2017 at 1457 CST.

"Event description: On 1/10/2017, Eagle US 2 was performing their annual inventory and operational checks of their licensed devices. During their routine annual maintenance checks, the shutter malfunction was discovered. The gauge shutter would not close.

"Eagle US 2 called a service contractor, BBP Sales, to evaluate the situation and determine the best course of action to correct the problem. [The contractor] was unable to close the shutter and will determine the course of corrective action. The cause appears to be the corrosive environment where it [the gauge] is installed and used.

"The source and device with shutter stuck open will remain installed and utilized on the process until the repairs are made. This is not a radiation exposure hazard and does not pose a health and safety situation for the Eagle US 2 employees or the general public.

"This event is considered closed by LDEQ. This event is being reported to the NRC as required by Regulatory Requirement 10 CFR 30.50(b)(2)."
