"University of Colorado Hospital (License Number: CO 828-01) had a misadministration of Y-90 microspheres (SIRTex SIRSpheres) on Wednesday, July 12, 2017. At approximately 11 [MDT], the post administration measurements of the waste from the SIRSpheres Administration indicated that the activity administered to segment 2/3 of the patient's liver was only 68.7 percent of the prescribed activity. The written directive called for an activity of 0.24 GBq and residual waste activity measurements indicated that 0.165 GBq was delivered. The physician indicated that stasis was not reached during the administration to this segment. There was a separate administration to segment [four] of the liver in which stasis was reached. "Follow-up information will be provided after they are available." A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient. | Agreement State | Event Number: 52853 | Rep Org: NV DIV OF RAD HEALTH Licensee: MET-CHEM TESTING LABS, INC.

A wind gust collapsed a steel tank and the scaffolding around it where a radiographer (met chem reciprocity) was working. The device fell approx. 60 ft., damaging the shutter end. The radiographer was not seriously injured and determined that the radiation source was secure and there was no leakage. He packaged the camera and returned to Utah."

"The RSO of Las Vegas Valley Water District reported the gauge missing. An operator was distracted before the transportation of the gauge and failed to block and brace the gauge or close the tailgate of the transport vehicle. The operator had forgotten the pound plate on-site and walked to where he left it, retrieved the plate but then was distracted and did not secure the gauge. He then started back to the office but realized part way back he had lost the gauge from the back of his vehicle. He retraced his steps, called the RSO and asked another operator to help find the gauge. The gauge was not found at that time. The RSO call the Las Vegas Metropolitan Police [LVMPD]. The Duty Officer for the State of NV, RCP [Radiation Control Program] was notified. "Update 01/28/2016: The RCP Duty Officer received a call from LVMPD ARMOR that the General Contractor on site found the gauge on 01/27/2016 and took it his storage and secured it over night. "Update 01/29/16: The person who found it was non English speaking and locked it up at his work. He brought it back in the morning to the general contractor who called Armor the next morning. John and I gave 3 violations for security, blocking & bracing and type A container breach (pop rivets with their license information). "We [Radiation Control Program] leak tested the gauge and it was negative, and they are having either Troxler or the local InstroTek repair it next week. It is tagged out of service right now. "Update 05/10/2016: The LVWD has retrained all staff on properly securing device prior to driving vehicles. Investigation is considered closed." The Troxler Model 3430 usually contains 8mCi of Cs-137 and 40 mCi of Am241/Be. Item Number: NV160002 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.

The gauge fell out of the back of a transport vehicle and was lost in Reno, Nevada. The gauge user set the gauge on the tailgate of his truck and took a phone call. He was distracted by the phone call and did not place the gauge in it's transport case or secure the gauge and drove back to the office where he realized the gauge had fallen out of the transport vehicle. The gauge user immediately called the RSO and retraced his route to find the gauge. The gauge was not found and it was reported to the Nevada Highway patrol, Washoe County Sheriff and Reno Police Department. The State is following the incident and working with local authorities to develop a press release. Follow-up information will be provided to NRC on the recovery of the lost gauge and entered into NMED.

"The RSO of Robinson Mine reported the shutter malfunction. He called the vendor to come on site and force the shutter closed. They were successful. The gauge was locked out/tagged out, but not removed from the service area in the mill central processing plant. The vendor stated the shutter malfunctioned because the shielding shifted due to process vibrations. The RSO has been instructed to submit a plan for the gauge." Gauge contained 1.85 MBq of Cs-137.

The individual who reported the event is a Nevada radioactive material licensee and said on 7/14/2017, at approximately 0735 [PDT], 'a nuclear density gauge was found in North Las Vegas at Cheyenne Ave and Berg St on the road. The gauge was recovered by an employee and quickly brought it to a secure storage location. The gauge was found in good condition and not damaged or source exposed.' At 0930 [PDT] on 7/14/2017, it was reported to the Nevada Radiation Control Program, by the ARSO from the company who lost the gauge, the gauge fell off the tailgate of a transport vehicle at a temporary jobsite, and the operator realized the loss and returned to the site within 5 minutes, but the gauge had already been recovered by [the reporting licensee]. The operator from [the licensee who lost the gauge] was informed that the gauge was recovered by [the reporting licensee] and relayed that information to the ARSO at [the licensee who lost the gauge]. The gauge was intact, no damage, transported back to the owner's storage location, and taken out of service. An investigation of the event will commence [on] 07/17/2017."

The failed starter was manufactured by Eaton Corporation in 2014 and purchased by Susquehanna from AZZ/NLI as part of an MCC bucket assembly. The starter failed with its contacts stuck in the energized state when it was de-energized. A failure analysis identified the contactor sticking to be due to the pole faces of the coil laminations and those of the armature laminations adhering to one another at normal operating temperatures. There was residue/material on the pole faces which closely matched Polydimethylsiloxane (PDMS) and silicone grease. One of the characteristics of PDMS is that at cooler temperatures it is more of a solid consistency, and at higher temperatures it becomes more viscous and tacky. "A previous Part 21 report submitted by Curtiss-Wright QualTech NP (Event Notification Number 51611) in December 2015 provided notification of Eaton/Cutler Hammer A200 series starters failures due to silicon based mold release that remained on the molded parts and would come between the moving (magnet) and fixed armatures. The Part 21 stated that when heated for extended period of time, the material would become sticky causing anywhere from a minor delay in opening to a frozen closed condition. Eaton/Cutler Hammer determined that the silicone mold release was first introduced into the manufacturing facility in May 2008 and used periodically until October 2012. According to Eaton/Cutler Hammer, any starters manufactured after January 1, 2013 should be silicon mold release free. "Following the failure of the 2014 starter at Susquehanna, Eaton Corporation performed an investigation and reconfirmed that silicon mold release was banned from molding production in October 2012 and has not been used since that time. Eaton concluded that the contamination does not appear to be systemic, but rather random and intermittent and that the contamination was most likely introduced either by operators and assemblers on the manufacturing lines, or by others who disassemble and inspect the product after shipment from their plant. Susquehanna does not take the components apart during receipt for testing or visual inspection. Eaton concluded that there is no evidence that the issue is systemic and considers it a random event. Susquehanna has evaluated the condition and has concluded that the condition could create a substantial safety hazard." The licensee notified the NRC Resident Inspector. | |
