| This material event contains a "Less than Cat 3 " level of radioactive material. | Event Text 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.

| Event Text AGREEMENT STATE REPORT - INDIVIDUAL OVEREXPOSURE OF PHARMACY TECHNICIAN
The following report was received from the Florida Department of Health Bureau of Radiation Control via email:
"[The Florida Department of Health Bureau of Radiation Control] received an email reporting an overexposure at Triad Isotopes Inc. On Jun 5, 2017, Triad's Corporate Safety Officer received exposure notifications (both whole body and ring dosimeters) from Landauer involving the same individual."
The first notification was for the period 4/1/2017 - 4/30/2017; doses were: whole body Deep Dose Equivalent (DDE) =2545 mrem, Lens Dose Equivalent (LDE) =2545 mrem, Shallow Dose Equivalent (SDE) =2452 mrem.
The second notification was for the period 5/15 - 5/21; doses were: left ring dosimeter 11000 mrem, right ring dosimeter 4670 mrem.
"On Jun. 5, 2017 Triad overnighted the whole body badge for the period of 5/1/2017 5/31/2017 to be read . Landauer notified Triad of the exposure notification on Jun. 9, 2017, whole body doses were: DDE=10953, LDE=14971 mrem, SDE=17913 mrem. Probable causes and corrective actions are outlined in the report from Triad. ERCM [Environmental Radiation Control Materials] will conduct the follow-up."
Technician A was immediately prohibited from entering the restricted area or handling radioactive materials. The isotopes involved are believed to be Mo-99/Tc-99m, Tc-99m, and Ga-68. An investigation was performed and identified the root causes as multiple procedural adherence issues, a human behavior error, and possible exposure to badges while not being worn. Retraining of all employees has been conducted and other steps are on-going.

"Containment atmosphere oxygen level was measured at 18.4 percent. This is below normal habitability level. The cause of the low oxygen level is a nitrogen leak inside containment Nitrogen has been isolated from containment and operators are preparing to purge containment."
The licensee notified the State of California, local authorities and the NRC Resident Inspector.
Notified the DHS SWO, FEMA OPS, USDA OPS, HHS OPS, DOE OPS, DHS NICC, EPA EOC. Notified FDA EOC, NuclearSSA, FEMA NWC and FEMA NRCC SASC via email.

The ALERT was terminated on 7/28/17 at 1819 PDT. The containment atmosphere was restored to normal conditions. The nitrogen source was isolated. The cause of the nitrogen leak into containment is under investigation.
The licensee will notify the NRC Resident Inspector. The licensee has notified the State of California and the local authorities. The licensee plans to issue a press release.

"On July 20, 2017, a fire protection supply line at BVPS [Beaver Valley Power Station] Unit 1 experienced a mechanical joint separation. When the mechanical joint separated there was an unplanned flow of water from the fire protection line to the ground, which eventually re-entered the Ohio River via storm drains. The source of the water to the BVPS Unit 1 Fire Protection System is the Ohio River. The fire protection water was not treated with chemical additives. The water flow from this fire protection line was terminated on the same day.
"Due to the situation described above, FENOC [FirstEnergy Nuclear Operating Company] provided written documentation describing this occurrence to the Pennsylvania Department of Environmental Protection, (PADEP) on July 28, 2017.
"This offsite notification to PADEP requires a 4-hour report per 10 CFR 50.72 (b)(2)(xi).
"No press release is planned.
"The NRC Resident Inspector has been notified." | |
