EN Revision Imported Date : 10/12/2020

EN Revision Text: LOSS OF TECHNICAL SUPPORT CENTER VENTILATION SYSTEM DUE TO PLANNED MAINTENANCE:

"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 planned maintenance affects the functionality of an emergency response facility. Planned maintenance activities are being performed on 09/28/20 to the Peach Bottom Atomic Power Station (PBAPS) Technical Support Center (TSC) HVAC. The work includes replacement of supply fan and roof-top unit. Work is scheduled to complete on 10/11/20.

"If an emergency is declared requiring PBAPS TSC activation during this period, the PBAPS TSC will be staffed and activated using existing Emergency Preparedness (EP) procedures. If the PBAPS TS becomes uninhabitable due to radiological, or other conditions, the TSC Station Emergency Director will relocate the TSC staff to an alternate location in accordance with EP procedures. The Emergency Response Organization team has been notified of the maintenance and the possible need to relocate during an emergency."

The NRC Resident Inspector will be notified by the licensee.

* * * UPDATE ON 10/9/20 AT 1234 EDT FROM BRIAN BAILEY TO ANDREW WAUGH * * *

"An eight-hour, non-emergency notification for a loss of Emergency Assessment Capability was made on 9/28/20 under Event Notification 54917 for planned maintenance activities to the Peach Bottom Atomic Power Station (PBAPS) Technical Support Center (TSC) ventilation system. This event was reportable in accordance with 10 CFR 50.72(b)(3)(xiii) because the planned maintenance affected the functionality of an emergency response facility.

"This update to EN 54917 is to notify applicable stakeholders that, following satisfactory completion of the planned supply fan and roof-top unit replacement work, the PBAPS TSC ventilation system has been returned to service with no remaining work or outstanding deficiencies related to this work."

The licensee has notified the NRC Resident Inspector. Notified R1DO (Lally).

AGREEMENT STATE REPORT - STOLEN TROXLER GAUGE

The following was received from the state of Texas (the Agency) by email:

"On October 1, 2020, the Agency was notified by the licensee's radiation safety officer (RSO) that a Troxler model 3430 moisture\density gauge containing a 40 milliCurie americium-241 source and an 8 milliCurie cesium-137 source was stolen from an employee's truck. The truck was parked at the employee's residence and when they came out to go to the job site they found both chains securing the gauge in the truck were cut and the gauge was missing. The RSO stated they had notified local law enforcement and the fire department.

"The RSO stated their management group was searching social media looking for the gauge. The RSO stated they currently have people in the field looking for the gauge. The RSO stated the gauge operating arm was locked. The gauge would not create an exposure risk to any individual unless the lock was cut off the operating arm and the cesium source exposed. Additional information will be provided as it is received in accordance with SA-300."

TX Incident # 9803.

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 - LEAKING SEALED SOURCE

The Florida Bureau of Radiation Control reported the following via email:

"The RSO [Radiation Safety Officer] notified the BRC [Bureau of Radiation Control] by mail that a leak test performed on this source [217.6 microCurie Cs-137 e-vial] resulted in greater than 0.005 microCi of the acceptable removable contamination. After determination, the source was sealed within the shielded e-vial container using silicone. The outer shielded container had no removable contamination. The sealed container was then wrapped in plastic. The outer plastic also had no removable contamination. The area was evaluated for signs of removable contamination with no results above background. The licensee intends to dispose of this source through a licensed radioactive waste disposal company."

AGREEMENT STATE REPORT - PACKAGE RECEIVED BY LICENSEE EXCEEDS SURFACE RADIATION DOSE LIMITS

The following information was received from the Commonwealth of Massachusetts via email:

"A shipment of radioactive material in the form of 5 packages, each containing 555 GBq of Americium/Beryllium, was delivered to QSA Global, Inc. at 0830 [EDT] on October 2, 2020, each of which exceeded regulatory package dose rate limits. All 5 packages exceeded the surface dose rate limit of 200 mrem/hour, the highest of which was 295 mrem/hour and the lowest 220 mrem/hour. Each package was labeled as Yellow III; TI 7. The transport index was also exceeded with a range of 13 mrem/hr at 1 meter for the lowest and 15 mrem/hr at 1 meter for the highest.

"It was reported that the final delivery carrier, [a common carrier], was notified of the event at 1430 [EDT] on October 2, 2020. The shipper, Weatherford International, LLC, at 7504 Benbrook Parkway, Benbrook, Texas, 76126, was also notified.

"The cause of the event is under investigation by the licensee. Further information from the Massachusetts Radiation Control Program will be forthcoming."

The Commonwealth will be notifying NMED.

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

"At 0315 [EDT] on October 11, 2020, Unit 2 ECCS [Emergency Core Cooling System] 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. At the current leakage (approximately 3.2 gpm), the dose analysis indicates dose to TSC inhabitants would exceed the 30 days REM TEDE [Total Effective Dose Equivalent] limit should leakage continue for the entire duration. 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."

AUTOMATIC REACTOR TRIP

"At 0026 [EDT] on October 12, 2020, D.C. Cook Unit 2 tripped automatically on low-low level of #24 steam generator which occurred after a lowering of main condenser vacuum.

"The reason for the lowering main condenser vacuum and the reason for the low steam generator #24 level is under investigation.

"This notification is being made in accordance with 10 CFR 50.72(b)(2)(iv)(B), Reactor Protection System (RPS) actuation as a four (4) hour report. Notification is also being made as an eight (8) hour report under 10 CFR 50.72(b)(3)(iv)(A) due to actuation of the Auxiliary Feedwater System (AFW).

"The D.C. Cook Resident NRC Inspector has been notified.

"Unit 2 is being supplied by offsite power. All control rods fully inserted. Auxiliary Feedwater Pumps started as required and are operating properly. Decay heat is being removed via steam generator power operated relief valves (PORVs) due to condenser steam dump unavailability from low main condenser vacuum. All four Reactor Coolant Pumps remain running. Preliminary evaluation indicates all plant systems functioned normally following the reactor trip. D.C. Cook Unit 2 remains stable in Mode 3. No radioactive release is in progress as a result of this event."
