EN Revision Text: AGREEMENT STATE REPORT - UNABLE TO DETERMINE IF SOURCE IN SHIELDED POSITION ON LEVEL INDICATOR

The following information was received via E-mail:

"On August 26, 2020, the Agency [Texas Department of State Health Services] was notified by the licensee's radiation safety officer (RSO) that while making preparations for the coming hurricane, the position of the source rod on a Tracerco, Model T-218-160032 [used for level indication] could not be confirmed. The source rod contains 10 cesium-137 sources of 10 milliCuries each (original activity.) The RSO stated when they return the sources to the shielded position, the control system does indicate the sources are shielded as indicated by a light change on the system console. When the licensee attempted to shield the sources on this day, the light did not change to indicate the sources were shielded. The gauge source rod is operated manually. They tried it a couple of times, but the light still did not change. A survey was performed on the outside of the vessel. The RSO stated there wasn't enough change in dose rate readings with shutter in the open and closed positions to determine whether the sources were shielded based on survey. The RSO stated it may be that the sources are not moving, or it may be that there is an issue within the control system causing the light not to change. They cannot determine at this time which problem is occurring. The RSO is contacting the manufacturer to send someone out after the hurricane. There is no risk of exposure. The RSO stated they will update the Agency once the manufacturer determines the problem. Additional information will be provided as it is received in accordance with SA-300."

Texas Incident Number: 9787

* * * RETRACTION ON 9/01/2020 AT 1406 EDT FROM ART TUCKER TO THOMAS HERRITY * * *

The following information was received via e-mail:

"On September 1, 2020, the licensee notified the Agency (Texas DSHS) that on August 31, 2020, a service company came onsite to investigate the shutter problem they had reported, and identified that there was no mechanical issue with the shutter. The problem they had was a failure of the output signal to indicate source position. The source rod was functioning normally. Based on this information, the Agency is retracting this event."

EN Revision Text: AGREEMENT STATE REPORT - LOST SHIPMENT OF TRITIUM EXIT SIGNS

The following was received from the Texas Department of State Health Services (the Agency) via email:

"On August 28, 2020, the Agency was contacted by an individual to notify it that they had shipped seven Forever Lite tritium exit signs to a manufacturer in May of 2020 and they have been informed by the transportation company that they do not know where the signs are. The signs are Forever Lite signs, each containing 7.03 curies (original activity) of tritium, manufactured in May 2011.

"The package was last scanned in Fort Worth, Texas, in May of 2020. The shipper stated that they were told on May 19, 2020 it was to be delivered in Canada. The next update when they followed up they were advised the package was lost and they were trying to locate the shipment and opened a claim. The location where the signs were lost is unknown at this time; therefore, the Agency is making this report for your information.

"The Agency has requested additional information and clarifications from the shipper. Additional information will be provided as it is received."

Texas Incident #: I - 9789

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. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf

* * * UPDATE ON AUGUST 31, 2020 AT 1126 EDT FROM ART TUCKER TO BRIAN LIN * * *

The following was received from the Texas Department of State Health Services (the Agency) via email:

"After reviewing documents provided by the licensee, the Agency contacted the licensee and confirmed that eight signs were lost and not seven as previously reported. The transportation company's radiation safety officer (RSO) was contacted by the Agency and the RSO stated they do not store the tracking records of shipments in their computer system for very long, therefore they would not be able to review the tracking information for this shipment. The Agency will provide additional information as it is received in accordance with SA-300."

AGREEMENT STATE REPORT - STOLEN VEHICLE WITH MOISTURE DENSITY GAUGE

The following was received from the Texas Department of State Health Services (the Agency) via email:

"The licensee notified the Agency at approximately 1315 CDT that one of its company pickups had been stolen and a Troxler model 3440 moisture/density gauge (SN: 37337) was secured in the bed of the truck. The gauge contains 40 milliCurie americium-241 and 8 milliCurie cesium-137 sources. The technician had a late testing and then went to his residence from the job site due to a serious water leak that was occurring there. After fixing the leak, it was late and he fell asleep and did not return the gauge to the licensee's facility. He last saw the vehicle/gauge at approximately 0100. At approximately 0900, he discovered the vehicle, with the gauge, had been stolen. The set of keys to the locks securing the gauge and the insertion rod were in the cab of the truck. Local police were notified. Police will notify the local pawn shops and the licensee will search local buy/sell/trade internet sites for the gauge and other equipment. More information will be provided as it is obtained in accordance with SA-300."

Texas Incident # I-9790

* * * UPDATE ON 08/29/20 AT 2018 EDT FROM KAREN BLANCHARD TO OSSY FONT * * *

The following update was received from the Texas Department of State Health Services via email:

"The licensee's Radiation Safety Officer notified the Agency at approximately 1847 CDT that he has possession of the gauge and it was back at their facility. He had been called by the San Antonio Fire Department HAZMAT at approximately 1800 that they had been called to a location where the gauge was - the gauge was sitting on the edge of a street next to the curb. The latches on the transport case were unlocked but the gauge and all other equipment were present. The chains and locks that secured the gauge in the bed of the truck were also present. There was no damage to the transport container or the gauge. Technicians put the device through its normal testing procedures and it is fully operational. Any further information will be provided as it is obtained in accordance with SA-300."

HIGH PRESSURE CORE SPRAY INOPERABLE

"River Bend Station experienced an inadvertent initiation and injection of High Pressure Core Spray (HPCS) at 2048 [CDT] on 9/3/2020 while operating at 92% power. Initial investigation indicates a power supply failure in the Division III trip units which feeds HPCS and Division III Diesel Initiation signals.

"The Control Room Operator responded to the event by taking manual control of Feedwater Level Control to maintain Reactor Water Level nominal values. The HPCS injection valve was open for approximately 25 seconds before operators manually closed the valve.

"The manual closure of the injection isolation valve caused the system to be incapable of responding to an automatic actuation signal. The manual override of the injection isolation valve was reset approximately 52 minutes after the event. The HPCS system has remained inoperable. The event is being reported in accordance with 10 CFR 50.72(b)(3)(v)(D) as a condition that caused loss of function of the HPCS System.

"No radiological releases have occurred due to this event.

"The Senior NRC Resident Inspector has been notified."

These conditions put the unit in a 14-day LCO (3.5.1) for HPCS Inoperability and a 30-day LCO (3.7.1) for one Standby Service Water Pump Inoperable (2C).

MANUAL REACTOR TRIP AND AUTOMATIC SAFETY INJECTION

"On September 4, 2020, DC Cook Unit 2 experienced a lowering Reactor Coolant System (RCS) pressure caused by a failed open Reactor Coolant Pressurizer Spray valve. At approximately 2242 [EDT], a manual Reactor Trip was performed due to the lowering RCS pressure. Following the manual reactor trip, an automatic Safety Injection was actuated due to the lowering RCS pressure. RCS pressure has recovered to normal and is stable.

"This notification is being made in accordance with 10 CFR 50.72(b)(2)(iv)(B), Reactor Protection System (RPS) actuation, and 10 CFR 50.72(b)(2)(iv)(A), ECCS Discharge to RCS, as a four (4) hour report. Notification is also being made as an 8 hour report under 10 CFR 50.72(b)(3)(iv)(A), Reactor Protection System (RPS), Containment Isolation, Emergency Core Cooling (ECCS), Auxiliary Feedwater System (AFW), and Emergency AC Electrical Power actuations. The DC Cook Resident NRC Inspector has been notified.

"Unit 2 is being supplied by offsite power. All control rods fully inserted. Aux Feedwater Pumps started as required and are operating properly. All ECCS components operated as required including Containment Isolation. Decay heat is being removed via the Condenser Steam Dumps and ECCS has been secured. Three of four Reactor Coolant Pumps were secured and RCS pressure has recovered to normal pressure and is stable. Preliminary evaluation indicates all plant systems functioned normally following the Reactor Trip and Safety Injection. DC Cook Unit 2 remains stable in Mode 3. No radioactive release is in progress as a result of this event."

Unit 1 was not affected and remains in Mode 1, 100 % power.

LONG TERM HABITABILITY OF TECHNICAL SUPPORT CENTER UNDER ACCIDENT DOSE ANALYSIS EXCEEDS CALCULATED ALLOWABLE VALUES

"At 034S [EDT] on September 6, 2020, Unit 2 ECCS leakage outside containment was determined to exceed the long term habitability dose analysis for the Catawba Nuclear Station Technical Support Center (TSC) under bounding conditions. Repairs are currently in-progress to arrest the leakage and restore functionality of the TSC.

"If an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing emergency planning procedures unless the TSC: becomes uninhabitable. If relocation of the TSC becomes necessary, the Emergency Director will relocate the TSC staff to the alternate facility.

"This is an eight-hour, non-emergency notification for a loss of Emergency Assessment Capability. This event is reportable in accordance with 10 CFR 50.72(b)(3)(xiii) because the discovered condition of the TSC affects the functionality of an emergency response facility.

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