| ENS 52866 | 19 July 2017 21:30:00 | 10 CFR 20.2201(a)(1)(ii) | Loss of Helicopter Integrated Blade Inspection System with 500 Microcurie Strontium 90 Source | At 1730 on 19 July 2017, HM-15 aircraft 13 had the Main Rotor Fairing, commonly referred to as the 'beanie', depart in flight. The 'beanie' cover is constructed of fiberglass, is circular in shape and 5 feet in diameter, weighing approximately 20 pounds. In addition to the beanie, we discovered that one of the In-flight Blade Inspection System (IBIS) Indicators also departed the aircraft. Loss of this IBIS Indicator is of concern because it contains strontium-90 which is radioactive material. Loss of this IBIS Indicator was not discovered until the aircraft shutdown on its line at Naval Station Norfolk. Location lost: Approximately 100 miles west of Norfolk, VA over the Roanoke River near Lake Gaston. The location is just north of the Virginia / North Carolina border over the Roanoke River approximately 3 miles east of the Kerr Lake Power Plant. 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.

| ENS 47529 | 14 December 2011 00:00:00 | 10 CFR 20.2201(a)(1)(ii) | Helicopter Integrated Blade Inspection System Source Lost | On 12/13/11, after a Marine Corps CH53 Helicopter training flight at 1900 PST it was determined during a post flight inspection that the 500 micro-Curie Sr-90 integrated blade inspection system (IBIS) source was missing. The flight originated on Marine Corps Air Station Miramar. During the flight the helicopter flew over the pacific ocean then to and over Camp Pendleton before returning to Miramar. An investigation into the event is ongoing. The results of the investigation will determine what actions are taken to recover the source. 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. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source | ||
| ENS 41713 | 16 May 2005 04:00:00 | 10 CFR 20.2201(a)(1)(ii) | Chemical Agent Detectors Missing from Department of Navy Inventory | A representative for the Navy's master materials license reported several chemical agent detectors missing based on the most recent inventory cycle. Specifically, 4 Chemical Agent Monitors (CAMs) are missing, with each CAM utilizing a 10 milliCurie Nickel-63 plated source (SSND# NR-1129-D-103-S) (40 millicuries of Ni-63 total). In addition, 1 Automatic Chemical Agent Detector Alarm (ACADA) containing two 10 milliCurie Ni-63 plated sources (SSND# NR-1129-D-101-S) is also missing (20 millicuries of Ni-63 total). These detectors have been reported missing from Marine Corp units deployed in Iraq. Details of the times, locations, and circumstances under which the detectors went missing are still under investigation by the Navy . | ||
| ENS 41541 | 23 March 2005 17:00:00 | 10 CFR 20.2201(a)(1)(i) | Chemical Agent Detectors Missing from Department of Navy Inventory | A representative for the Navy's master materials license reported a number of chemical agent detectors missing based on the two most recent inventory cycles. Specifically, 27 Chemical Agent Monitors (CAMs) that utilize a 10 milliCurie Nickel-63 plated source (SSND# NR-1129-D-103-S) are missing (270 millicuries of Ni-63 total). In addition, 11 Automatic Chemical Agent Detector Alarms (ACADAs) with two 10 milliCurie Ni-63 plated sources in each detector (SSND# NR-1129-D-101-S) are missing (220 millicuries of Ni-63 total). The majority of these detectors have been reported missing from Marine Core Logistics Base in Albany, GA. However, a number of these detectors have been distributed to Marine Expeditionary Units in the field. Details of the times, locations, and circumstances under which the detectors went missing are still under investigation by the Navy and will be reported in a followup 30-day written report. The licensee has contacted the NRC Regional Inspector (Masnyk-Bailey) and HQ contact (Bhachu). | ||
| ENS 41520 | 23 March 2005 15:45:00 | 10 CFR 30.50(b)(2) | Failure of Safety Equipment on Radiography Camera | A representative for the Navy's master material license reported a safety equipment failure of a Gamma Radiography Camera with a 16 curie Iridium-192 source (Model 660) that was being used at the Norfolk Naval Shipyard. After an exposure with the camera had been completed, the radiographer was retracting the source and could not lock it into its safe position. After a second attempt, the radiographer was able to lock the source in place manually - the locking ring did not lock automatically as designed. The radiographer noted that the retraction cable on the camera had also become disconnected from the camera. The camera is being returned to the vendor (AEA) for inspection and repair. A 30 day written followup report will be provided. The licensee has notified the NRC regional inspector (Masnyk-Bailey) and NRC HQ (Bhachu). The licensee stated that this report was being provided to the NRC under 10 CFR 34.101(a))(3). | ||
| ENS 41519 | 2 March 2005 05:00:00 | 10 CFR 20.2201(a)(1)(i) | Receipt of Radioactive Material Without Proper Control | An 89 curie Iridium-192 Gamma Radiography Camera (Model 660) was received at a Naval warehouse in Guam without proper controls or receipt inspection. The Navy Master Materials licensee representative states that the radiography camera was sent by AEA (the camera vendor) to a submarine tender stationed in Guam without preshipment notification or any request for the camera by Naval personnel stationed on the tender. The camera was received by the warehouse on March 2, 2005, and placed in warehouse storage without procedural control related to the receipt of radioactive materials. On March 14, 2005, during unrelated survey of materials in the warehouse, the camera was discovered. The submarine tender radiographer was contacted and performed receipt inspection and survey and determined that there is not radiological problems and the camera source is in its proper safe storage position. This event is still under investigation and a 30 day written followup report will be prepared. The licensee is reporting this event under 10 CFR 20.2201(a)(1) because the material was not under proper control from March 2 through March 14, 2005. The licensee has notified the NRC regional inspector (Masnyk-Bailey) and NRC HQ (Bhachu). | ||
| ENS 41608 | 30 September 2003 17:00:00 | 10 CFR 20.2201(a)(1)(i) | Chemical Agent Detectors Missing from Department of Navy Inventory | A representative for the Navy's master material license reported two chemical agent detectors were missing since their last audit on 9/30/2003. One detector was a Automatic Chemical Agent Detector Alarms (ACADA) which has 230 microcuries of Am241 with a surface exposure of 0.4 millirem/hr. The identification number is SSND -NR-1065-D-101-E. The other detector was a hand held vapor detector containing a 10 microCurie Ni63 source with identification number SSND-NR-0399-D-101-E. The licensee was informed by a supply room person that the detectors were assigned to the USS Fletcher on 9/30/03, and have not been accounted for since. |
