TEXAS AGREEMENT STATE REPORT - STOLEN TROXLER GAUGE

The following information was obtained from the State of Texas via email:

"On May 14, 2018, the licensee notified the Agency [Texas Department of State Health Services] that on the morning of May 12, 2018, one of its Troxler model 3430+ moisture/density gauges (SN: 69854), containing a 40 milliCurie americium-241 source (SN: 47-19592) and an 8 milliCurie cesium-137 source (SN: 77-13965), had been stolen from a licensee's vehicle while it was parked at a restaurant in Houston, Texas. The gauge was locked inside its transport case which was secured with chains in the back of the licensee's vehicle. The technician had stopped to eat breakfast between picking up the gauge at the licensed site and reporting to the temporary job site. When he arrived at the job site, he found the chains cut, the gauge and standard plate had been stolen, but the transport case was still there. The technician reported the theft to his supervisors who did not report to the licensee's radiation safety officer until May 14th. The theft has been reported to local law enforcement. An investigation into this event is ongoing."

Texas Incident Number: 9571


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.

OFFSITE NOTIFICATION REGARDING MALFUNCTION OF EMERGENCY NOTIFICATION SIREN

"On May 21, 2018, at approximately 0840 Eastern Daylight Time (EDT), Duke Energy confirmed that one emergency notification siren (i.e., B13) located in Brunswick County was malfunctioning. The siren was making an abnormal sound, alternating between low and high pitch. The siren was deactivated upon confirmation of the siren malfunction. There are a total of 38 sirens located in Brunswick and New Hanover Counties. No other sirens were affected.

"Duke Energy notified the State of North Carolina, Brunswick County, New Hanover County and Coast Guard of the issue.

"There was no impact on the health and safety of the public or plant personnel. The NRC Senior Resident Inspector has been notified."

UNPLANNED PUBLIC NOTIFICATION DURING A DRILL

"On 05/22/2018, Cooper Nuclear Station (CNS) was conducting an Emergency Response Organization (ERO) drill which included state and local involvement. At approximately 09:00 CST Nebraska Emergency Management Agency (NEMA) inadvertently broadcasted CNS' declaration of a Notice of Unusual Event for the drill over the public scanner. This resulted in various members of the public or news media inquiring about the perceived event or posting erroneous information via Twitter, television news outlets, newspapers, and radio stations. These news outlets have been informed that CNS was conducting a drill and do not intend to release any stories regarding this event. There is no evidence of a formal news release at this time. However, due to the uncontrolled source of the information, the determination was made to make this report.

"This unplanned media event is a 4 hour report, in accordance with 10CFR50.72(b)(2)(xi). This event is not significant with respect to the health and safety of the public.

"The licensee notified the NRC Resident Inspector."

GAS VOIDS DISCOVERED IN BOTH TRAINS OF LOW HEAD SAFETY INJECTION

"On 5/22/2018, while operating at approximately 100 percent power, Ultrasonic Testing of the Beaver Valley Power Station (BVPS) Unit 1 Low Head Safety Injection (LHSI) pump suction piping identified gas voids in excess of the acceptable limit for void volume. Both trains of LHSI were declared inoperable. Technical Specification (TS) 3.5.2 for both trains of the LHSI system was entered along with TS 3.0.3 which requires the initiation of a plant shutdown. Time of TS entry was 12:56 (EDT).

"Plant shutdown was commenced at 15:56 (EDT) in accordance with plant procedures.

"At 15:59 (EDT) Train 'A' LHSI was restored to operable status, TS 3.0.3 Action was exited and the power reduction was stopped at approximately 99 percent.

"At 17:43 (EDT) Train 'B' LHSI was restored to operable status, TS 3.5.2 Actions were exited.

"This is reportable per 10 CFR 50.72(b)(3)(ii) Unanalyzed Condition, 10 CFR 50.72(b)(3)(v) Event or Condition that Could Have Prevented the Fulfillment of a Safety Function and 10 CFR 50. 72(b )(2)(i) TS Required Shutdown.

"The NRC Resident Inspector has been notified."

* * * RETRACTION ON 6/21/18 AT 1535 EDT FROM SHAWN KEENER TO RICHARD SMITH * * *

"Further engineering evaluation has determined that the gas voids that existed at the time of discovery would not have rendered the LHSI [Low Head Safety Injection] system inoperable if it were required to actuate. The engineering evaluation concluded that filling of the containment sump during a Design Basis Accident would result in a void volume reduction such that the void in the LHSI suction piping would not be large enough to significantly impact the operability of the system. Therefore, the system remained operable but degraded. No TSs [Technical Specifications] were required to be entered and no shutdown was required. As such, all three reporting criteria do not apply and are being retracted.

"The NRC Resident Inspector has been notified."

Notified R1DO (Burritt).
