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.

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."

PART 21 - WEAR OF THERMAL SLEEVE IN WESTINGHOUSE CONTROL ROD DRIVE MECHANISMS

The following notification is an excerpt from the received report:

"Westinghouse nuclear steam supply system (NSSS) plants that have thermal sleeves in the control rod drive mechanism (CRDM) penetration tubes, wear of the thermal sleeve flange against the tube could have safety consequences that were not previously considered. Recent operating experience, during startup procedures at an Electricite de France (EdF) plant, has shown the possibility for the flange remnant from a thermal sleeve to interfere with control rod movement."

Potential affected plants include, A. W. Vogtle 1 & 2, Braidwood 1 & 2, Byron 1 & 2, Callaway, Catawba 1 & 2, Comanche Peak 1 & 2, Diablo Canyon 1 & 2, McGuire 1 & 2, Millstone 3, Seabrook, Sequoyah 1 & 2, Shearon Harris, South Texas 1 & 2, Watts Bar 1 & 2, Wolf Creek, Beaver Valley 1 & 2, D.C.

LOSS OF EMERGENCY ASSESSMENT CAPABILITY

"At time 0848 (CDT), Main Steamline Radiation Monitor 2-RE-2328 (Main Steamline 2-04) lost communications and was declared non-functional.

"With this radiation monitor non-functional, all of the emergency action levels for a steam generator tube rupture in steam generator 2-04 could neither be evaluated nor monitored. This unplanned condition is reportable as a loss of assessment capability per 10CFR50.72(b)(3)(xiii).

"Comanche Peak Nuclear Power Plant [CPNPP] has assurance of steam generator integrity and fuel cladding integrity and there is a negligible safety significance to the current condition from a public health and safety perspective.

"Additionally, compensatory measures are in place to assure adequate monitoring capability is available to implement the CPNPP emergency plan in the unlikely event of challenges to the steam generator or fuel cladding. The N16 radiation monitor serves as a backup with alarm function and Radiation Protection technicians have been briefed on taking local readings with a Geiger-Mueller tube on MSL 2-04.

"Corrective actions are being pursued to restore 2-RE-2328 to a functional status.

"The NRC Resident Inspector has been notified."

AUTOMATIC REACTOR TRIP ON LOW DEPARTURE FROM NUCLEATE BOILING RATIO

"The following event description is based on information currently available. If through subsequent reviews of this event additional information is identified that is pertinent to this event or alters the information being provided at this time a follow-up notification will be made via the ENS or under the reporting requirements of 10CFR50.73.

"On May 23, 2018, at approximately 1128 Mountain Standard Time (MST), the Palo Verde Nuclear Generating Station (PVNGS) Unit 2 control room received reactor protection system alarms for low departure from nucleate boiling ratio and an automatic reactor trip occurred. Prior to the reactor trip, Unit 2 was operating normally at 100 percent power. Plant operators entered the reactor trip procedures and diagnosed an uncomplicated reactor trip. All CEAs [control element assemblies] fully inserted into the core. No emergency classification was required per the PVNGS Emergency Plan.

"The Unit 2 safety-related electrical buses remained energized from normal offsite power during the event. There was no impact to the required circuits between the offsite transmission network and the onsite Class 1E Electrical Power Distribution System; the offsite power grid is stable.

"No major equipment was inoperable prior to the event that contributed to the event or complicated operator response. Unit 2 is currently stable in Mode 3 with the reactor coolant system at normal operating temperature and pressure. The cause of the reactor trip is under investigation.

"The event did not result in any challenges to fission product barriers and there were no adverse safety consequences as a result of this event. The event did not adversely affect the safe operation of the plant or the health and safety of the public.

"The NRC Resident Inspector has been informed of the Unit 2 reactor trip."

Decay is being removed via steam dumps to condenser. Units 1 and 3 at Palo Verde were unaffected by the transient and continue to operate at 100 percent power.
