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.

CONTAMINATION DETECTED IN SOURCE STORAGE ROOM IN 2008
The following is excerpted from statements recorded by the RSO on Aug 26th, 2009, concerning contamination discovered by the licensee in [the source storage room] Feb/Mar 2008, of their facility:
"1. A source being held in storage was discovered to have external contamination about Feb/Mar 2008. The source was being prepared for an upcoming disposal of sources. The source was in storage in a vault in the [source storage room at their facility]. This room is primarily used to do survey meter calibrations.
"2. When the contamination was discovered the techs were directed to not use the room. Any activities (detector calibrations) requiring that area were conducted by the RSO. The area was evaluated for contamination. Spots of contamination were found and found to exist only in the back room area. Decontamination of the area was done. The room was back into use for all techs to use by the summer of 2008.
"3. [The RSO] was made aware of the question of personnel contamination the spring of 2009. A device to assess such contamination is not readily available. A scanner to assess any such contamination does exist at the Bethesda Naval Medical Center. [The RSO] has recently made contact with the Commander in charge of the unit and have obtained information necessary to have access to the device. The basic detail for access is a cost of $1200 to have a scan performed.
"4. There are policies and procedures in place to deal with contamination.
"5. The question of contamination has only been raised recently and through the union as a grievance. An assessment of any contamination requires the availability of the device to obtain the information. Access to a scanner has been found and steps are to be taken to schedule the scan. The initial step will be the approval and allocation of funds to pay for the scan. Then arrangements can be made to have access to the Bethesda Naval Medical Center in order to do the scan." |

AGREEMENT STATE REPORT - MEDICAL EVENT INVOLVING LESS THAN THE PRESCRIBED DOSE DELIVERED TO PATIENT
The following report was received from the State of California via email:
"At approximately 1000 PDT on May 5, 2015, a medical event occurred during a Y-90 Therasphere procedure. The prescribed dose to the organ (liver) was 12,000 rem, but the delivered dose was 6,920 rem. This event meets the 10 CFR 35.3045(1)(i) 24-hour report criteria since the dose differed from the prescribed dose by more than 50 rem to an organ (5080 rem under dose) and the total dose delivered differed from the prescribed dose by 20 percent or more (42% under dose). Although the equipment indicated the entire dose had been delivered to the patient, a large amount of the dose was is still in the tubing and vial and had not actually been delivered to the patient as indicated. The licensee will contact the manufacturer to assist in finding the root cause of the malfunction to determine whether it was an equipment malfunction, operator error, or both. The treating physician is also the prescribing physician. The licensee has contacted the physician to verify if the physician has notified the patient and if there was any effect on the individual from this event. The licensee will provide the written report within 15 days as required which will also describe what actions will be taken to prevent reoccurrence."

AGREEMENT STATE REPORT - STOLEN THERMO FISHER XRF ANALYZER
The following information was received from the New York Department of Health [DOH] via fax:
"The Department of Health (DOH) became aware of this incident on 5/6/15. The DOH phoned the Vice President of Metro Metal Recycling, LLC on an unrelated detail of license C3062 renewal. The licensee stated on 5/6/15 that he did not need the license anymore because on 1/27/15, his Thermo Fisher XRF, Model XLP 818, Serial Number 13149, had been stolen. He had not contacted DOH to report the stolen XRF, which contained 30 millicuries of americium-241. He did notify Colonie Police and obtained a police report. He e-mailed a copy of the police report and photographs of a damaged metal fence to DOH. The police report states that an unknown person broke the lock to their gate, broke an office window and entered the office where they stole the XRF from an unlocked desk drawer. There was no surveillance video. The guard dogs have access to the metal storage area but not the office area. The Vice President was sent an e-mail requesting additional information."
The Thermo Fisher XRF (X-Ray Fluorescence) Analyzer is used to identify metal alloys.

INADVERTENT INTRODUCTION OF ALCOHOL INTO THE PROTECTED AREA
"On May 7, 2015, at 1515 hours, B&W NOG-L Security management determined alcohol had been inadvertently introduced into the Protected Area through the shipping and receiving process. 10 CFR 26.719(b)(1) requires that the licensee report to the Operations Center within 24 hours of discovery, the use, sale distribution, possession, or presence of illegal drugs, or the consumption or presence of alcohol within a protected area. The item in question was a six pack of bottled beer which was part of a box of promotional items personally delivered by a sales representative from Graybar Electric.
"The B&W employee addressee first became aware of the package through an email and voicemail left by the salesman advising of a package delivery and indicating the presence of alcohol in the package. The B&W employee immediately contacted Shipping and Receiving management at approximately 1300 hrs. in an effort to intercept the package before delivery; however the package had already been processed into the Protected Area.
"Shipping and Receiving Management contacted the delivery driver via radio and instructed the driver not to deliver the package. The delivery driver separated the package from the delivery items. The package was removed from the Protected Area and returned to the Shipping and Receiving Manager located in the Owner Controlled Area at approximately 1500 hrs. The package was returned unopened. B&W Security Management was notified of the incident at approximately 1515 hrs.
"All items processed through Shipping and Receiving undergo security x-ray inspection. Containers of liquid are commonly processed items and therefore did not create an elevated level of suspicion which would have led to the officers conducting a visual inspection.
"B&W NOG-L Management will conduct an evaluation of the incident to include root cause analysis and corrective actions to prevent recurrence."

UNANALYZED CONDITION DUE TO EXCESSIVE TOXIC CHEMICALS ONSITE
"On May 14, 2015, it was determined that the number of 55 gallon drums of 2-Butoxyethanol analyzed to be transported and stored within the owner-controlled area (OCA) at any one time had been exceeded. It was discovered that contrary to the toxic gas analysis performed, fourteen 55-gallon drums of 2-Butoxyethanol were transported and stored in the OCA to support the construction of a dome being built to provide storage for FLEX equipment. The number of drums exceeded the limitation specified in the toxic gas analysis performed as part of the design project for transportation and storage could potentially impact Control Room habitability, emergency diesel generator air intake and have an adverse impact on security personnel.
"Upon determination that an unanalyzed condition existed, Operations placed the control room ventilation system in the 'isolation mode' until the number of drums on-site was reduced within the analyzed number. A substantial covering had been placed over the drums which also decreased the likelihood that any of the drums would fail and would also limit the potential dispersion of chemicals should a breach occur.
"The excess number of drums of 2-Butoxyethanol being transported and stored on-site is considered an unanalyzed condition that significantly degraded plant safety and is reportable in accordance with 10CFR50.72(b)(3)(ii)(B)."
The allowed number of 55 gallon drums of 2-butoxyethanol allowed per the current toxic gas analysis is 4 drums. The number of drums has been reduced to 2 as of 2024 EDT.
The licensee has notified the NRC Resident Inspector. |
