AGREEMENT STATE REPORT - CONTAMINATED RADIATION WORKER

The following was received from the Oklahoma Department of Environmental Quality via email:

"A person administering a dose of I-131 to a cat at Oklahoma State University (OK-00237-03) was found to have contamination on the palm of one hand after the injection. According to the licensee, the contaminated individual is a radiation worker. The amount of material on the individual is estimated at 0.17 microCuries and it is believed to have been on the person for 15 to 30 minutes. After the discovery, the person was decontaminated, which reduced the radiation level to background. The [contaminated individual] will be bio-assayed tomorrow."

AGREEMENT STATE REPORT - FIXED GAUGE STUCK SHUTTER

The following report was received from the state of Texas via e-mail:

"On March 21, 2019, the licensee notified the Agency [Texas Department of State Health Services] that during routine shutter checks on March 20, 2019, it had discovered that the shutter on one of the Ronan Model SA-1 gauges (SN: M-3824) was stuck in the open position. Open is the normal operating position for this gauge. The gauge contains a cesium-137 source with a calculated current activity of 10 milliCuries. Due to the location of the gauge, there is no increased risk of exposure. The licensee plans to replace the gauge."

AGREEMENT STATE REPORT - STOLEN MOISTURE DENSITY GAUGE

The following was received from the state of Alabama via fax:

"On March 20, 2019 at approximately 0800 [CDT], [an individual] of Alabama licensee TTL, lnc. notified the Alabama Office of Radiation Control [Agency] that gauge make and model Troxler 3440P was stolen from a technician's vehicle between approximately 2000 [CDT] March 19, and 0500 [CDT] March 20, 2019. The technician was working at a temporary job site in Auburn, AL, and the truck parked in the hotel parking lot. [The individual] reported that the technician stored the gauge in a gauge box; the gauge box was appropriately secured to the truck bed. The technician reported the theft to the local police department before contacting the Agency. The Agency has no further information regarding the whereabouts of this gauge as of today, March 21, 2019.

"TTL, Inc. is authorized to possess gauges under Alabama license 512. The stolen gauge is identified as Troxler model 3440P [serial number] 72314, with maximum source activities of 10 mCi Cs-137 and 50 mCi Am/Be-241."

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.

AGREEMENT STATE REPORT - GENERATOR LOST IN TRANSIT

The following was received from the state of George via e-mail:

"On January 17, 2019, GE Healthcare in Atlanta (GA 1166-1) consigned a Mo-99/Tc-99m generator (5.14 mCi at the time of shipment) to [common carrier] for delivery to Medi-Ray in Tuckahoe, NY for recycling (the trip included a transit stop in Charlotte, NC). As of March 20, 2019, the device has not arrived at its final destination. On March 18, 2019, [the common carrier] formally notified GE Healthcare that the device was lost in transit.

"This information was received on March 20, 2019."

UNUSUAL EVENT DECLARED DUE TO RCS UNIDENTIFIED LEAKAGE

At 1450 EDT on March 28, 2019, the licensee observed that the Unit 1 unidentified Reactor Coolant System (RCS) leakage was greater than 10 gallons per minute (gpm) for greater than or equal to 15 minutes. The licensee declared an Unusual Event in accordance with their EAL SU 5.1. The licensee initiated a unit shutdown in accordance with their procedures and the unit was approximately 58 percent reactor power at 1507 EDT, with unit shutdown in progress. The licensee also received an alarm due to increasing Drywell Pressure at 1.7 pounds drywell pressure.

At 1600 EDT the licensee called with an update. Unit 1 was still in an Unusual Event with the unit at 37 percent power with the shutdown continuing. Drywell Pressure had decreased to 0.8 pounds. At 1603 the licensee scrammed Unit 1.

Notified DHS SWO, FEMA Operations Center, DHS NICC, FEMA NWC (email), DHS Nuclear SSA (email), and FEMA NRCC SASC (email).

* * * UPDATE ON 3/28/2019 AT 1808 EDT FROM MARK TURKAL TO THOMAS KENDZIA * * *

"At 1437 EDT on March 28, 2019, with Unit 1 in Mode 1 at approximately 100 percent power, a Technical Specification-required shutdown was initiated due to indication of a leak in the drywell. Technical Specification Action 3.4.4.A, Unidentified Reactor Coolant System (RCS) leakage increase not within limit, requires RCS leakage to be reduced to within limits within 8 hours.

"It is expected that the leakage would not have been reduced to within limits within the required Technical Specification completion time; therefore, this event is being reported in accordance with 10 CFR 50.72(b)(2)(i).

"There was no impact on the health and safety of the public or plant personnel.

"The NRC Resident Inspector has been notified."

* * * UPDATE ON 03/29/19 AT 0302 EDT FROM TOM FIENO TO BETHANY CECERE * * *

At 0259 EDT on March 29, 2019, the Unusual Event was terminated because RCS leakage was reduced to less than 10 gallons per minute. The most recent leakage rate measured at 0225 EDT was 3.9 gpm. The source of the leak will be identified when plant conditions allow containment entry. No elevated radiation levels were observed during this event. Drywell pressure is currently 0.0 psig. Unit 1 is in Mode 4.

The licensee notified the NRC Resident Inspector.

Notified R2DO (Bonser), NRR EO (Miller), IRD MOC (Grant), DHS SWO, FEMA Operations Center, DHS NICC, FEMA NWC (email), DHS Nuclear SSA (email), and FEMA NRCC SASC (email).

AUTOMATIC ACTUATION OF THE PRIMARY CONTAINMENT ISOLATION SYSTEM AND THE REACTOR PROTECTON SYSTEM

"At 1654 EDT on March 28, 2019, with Unit 1 in Mode 3 at 0 percent power, an actuation of the Primary Containment Isolation System occurred, closing the outboard Main Steam Isolation Valves (MSIVs) due to a low condenser vacuum signal. The MSIVs had been manually closed, per procedure, during the shutdown evolution to address drywell leakage. The inboard MSIVs had not been reopened when the isolation occurred.

"Subsequently, at 1658 EDT a Reactor Protection System (RPS) actuation occurred due to reactor water level dropping below the actuation setpoint. All control rods were inserted at the time of the actuation.

"This event is being reported in accordance with 10 CFR 50.72(b)(3)(iv)(A) as an event that results in valid actuations of the Primary Containment Isolation System and the Reactor Protection System.

"There was no impact on the health and safety of the public or plant personnel. The safety function of both the MSIVs and the RPS had already been completed at the time of the event.

"The NRC Resident Inspector has been notified."
