The following report was received from the Texas Department of State Health Services via email:
"On August 11, 2016, the Agency [Texas Department of State Health Services] was notified by the licensee that during a routine annual inspection, the shutter on an Ohmart Vega SH-F1 nuclear gauge could not be operated. The gauge contains a 15 millicurie (original activity) source. The shutter's operating handle no longer operates the shutter. It is in the open position which is the normal operating position for the shutter. A service company is on site and will try to repair the gauge. The gauge is mounted on the top of a tall vessel and does not present an exposure hazard to the licensee's workers or members of the general public. This event is similar to EN 52167. Additional information will be provided as it is received in accordance with SA-300."

The following is an excerpt from a report received from the Texas Commission on Environmental Quality via email:
"A fire occurred within the Mestena Uranium LLC License Area in the vicinity of PAA-3 on August 9, 2016. The fire was discovered at approximately 1545 CDT by US Border Patrol agents who were conducting activities in the vicinity. Mestena personnel discovered the fire at about the same and upon investigation determined the fire required additional support at which time the local fire department was notified and arrived on site at approximately 1620 CDT to battle the fire.
"Fire crews declared the fire out/controlled by 2000 [CDT]. No injuries occurred during the firefighting activities.
"[The licensee] contacted [The Texas Commission on Environmental Quality] by telephone at approximately 2110 [CDT] to inform [them] that the fire was declared out and that an investigation into the fire will be initiated which will include follow-up actions required to remediate any impacts caused by the fire.
"The fire burned approximately 60 acres, most of which was within the PAA-3 Mine Area. The fire damaged or destroyed surface infrastructure associated with the in-situ mining activities permitted under UIC permit UR03060PA3.
"As a precaution, high volume air samples were collected while the firefighting was occurring. Samples were collected from downwind locations along the perimeter of the fire zone. Additional samples were collected on August 10th . Bioassay samples were also collected from individuals who participated in the firefighting activities.
"A written report that conforms to 30 TAC 336.335(c)(2) will be submitted to TCEQ [Texas Commission on Environmental Quality] within 30 days."

| This material event contains a "Less than Cat 3 " level of radioactive material. | Event Text AGREEMENT STATE REPORT - MISSING GAUGE WITH 100 MILLICURIE CO-60 SOURCE
The following report was received from the Tennessee Department of Environment and Conservation Division of Radiological Health via email:
"Licensee reported that a gauge with a 100 mCi Co-60 source was missing from a shipment with a carrier. Licensee accounted for the source upon leaving the licensee's facility. Licensee states that source is still in carrier's warehouse in Knoxville, TN, or in route to another site in Louisiana. Licensee is investigating warehouse and transport. A follow-up report will be sent upon receiving further information; this will include model number, activity, and shipping information."
TN State Event Report ID No.: TN-16-111
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.

At approximately 1820 EDT on 8/11/16, St. Clair Power Plant, a coal-fired generation unit, caught fire in East China Township, Michigan. The Radiation Safety Officer (RSO) reported that 22 nuclear gauges (Texas Nuclear Model 5181, 5193, 5180A, 5192 and Ohmart Model SHGS-2, SH-100, SR-A) are used at the site which all contain Cs-137. The RSO will conduct an assessment of all the nuclear gauges on 08/12/16.

"On 8/11/16 at approximately 1820 EDT, the DTE Energy St. Clair Power Plant experienced a mechanical failure in the Unit 7 Turbine that resulted in a fire. The DTE Energy Radiation Safety Officer conservatively made an immediate report (within 4 hours) to the NRC on 8/11/16 at 2215 EDT based on the immediate reporting requirements of 10 CFR 30.50(a) due to, at the time, unknown conditions of nuclear gauges located in the area of the fire. The nuclear gauges are used for level measurement purposes.
"On 8/12/16, the DTE Energy Radiation Safety Officer completed an assessment of all nuclear gauges associated with the unit 7 fire. No gauges were found damaged or compromised. All unit 7 gauges were visually inspected with no structural damage identified. Radiological surveys were performed on all unit 7 gauges. Results of the radiological surveys showed normally expected dose rates and no loose surface contamination. Shutter mechanisms were closed and locked closed on all gauges in unit 7. Nuclear gauges in other units of the St. Clair Power Plant were not impacted by the fire event. These gauges were visually inspected and no signs of damage were identified. Based on the results of this assessment, DTE Energy retracts notification 52175."

The following was received from State of Maryland via email:
"Greater than 20 percent underadministration of the prescribed activity was administered to the left lobe of the patient's liver. Underadministration may have been up to 60 percent less than the prescribed written activity (preliminary estimate). Prescribed written directive activity to left lobe of liver was 25 mCi. Preliminary assessment of administered activity is 14 mCi. Radioactive material ended up in the patient catheter, chucks, and on the floor. All areas were cleaned and evaluated by the licensee. The licensee states that both the patient and referring doctor have been notified of the event. The licensee has history of many successful therapies of this type. The licensee is investigating the event, but has not yet determined a root cause. The licensee is sending a detailed written report to the State."
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. |

At 35 percent power, a main generator lockout caused the main generator to trip, resulting in a reactor trip of Unit 1. Because of the lockout, power did not transfer to the startup transformers. Both emergency diesel generators started and aligned to the emergency busses.
During the trip all control rods fully inserted and no safety or relief valves lifted. The plant is in Mode 3 steaming through the atmospheric relief valves and feeding the steam generators using auxiliary feedwater. There is no reported primary to secondary leakage. Primary coolant is being moved using natural circulation cooling.
The trip of Unit 1 had no effect on Unit 2. The licensee notified the NRC Resident Inspector.
Notified DHS SWO, FEMA, DHS NICC, and Nuclear SSA (via e-mail).

"On August 21, 2016 at 1926 EDT, St. Lucie Unit 1 experienced a reactor trip and a loss of offsite power due to a main generator inadvertent Energization Lockout Relay actuation. The cause of the lockout is currently under investigation. Coincident with the loss of offsite power, the four reactor coolant pumps deenergized. Both the 1A and 1B Emergency Diesel Generators started on demand and powered the safety related A/C buses. All CEAs [Control Element Assemblies] fully inserted into the core. Offsite power to the switchyard remained available during the event, and at 2036, restoration of offsite power to St. Lucie Unit 1 was completed. Decay heat removal is being accomplished through natural circulation with stable conditions from Auxiliary Feedwater and Atmospheric Dump Valves. Currently maintaining pressurizer pressure at 1850 psia and Reactor Coolant System temperature at 532 degrees F.
"St. Lucie Unit 2 was unaffected and remains in Mode 1 at 100% power.
"This report is submitted in accordance with 10 CFR 50.72(b)(2)(iv)(B) for the reactor trip and 10 CFR 50.72(b)(3)(iv)(A) for the Specified System Actuation."
