AUXILIARY BUILDING GAS TREATMENT SYSTEM INOPERABLE

"At 1730 EDT on 10/27/2013, SQN [Sequoyah Nuclear] discovered that Unit 1 containment penetration X-108 had a maintenance flange installed with a service air connection attached. The service air connection was connected to a temporary air compressor supplying air to maintenance loads inside Unit 1 containment. Contrary to the requirements of the breaching permit, personnel were not stationed at the penetration to isolate the service air connection in the event of the air line rupturing inside Unit 1 containment or upon initiation of an auxiliary building isolation signal. Since the Unit 1 containment is open to the auxiliary building as part of outage activities, if the service air line had ruptured, the additional air into the Unit 1 containment could have exceeded the capacity of the Auxiliary Building Gas Treatment System (ABGTS) and potentially have impacted the ability of the ABGTS to perform its design safety function. This resulted in both trains of the ABGTS being declared inoperable requiring Unit 2 to enter the action of LCO 3.0.3. The service air line was isolated immediately and Unit 2 exited the action of LCO 3.0.3 at 1732 EDT. At the time of the event, Unit 1 was defueled and did not require ABGTS to be operable. Unit 1 subsequently entered Mode 6 at 1904 EDT on 10/27/2013 and is currently conducting refueling operations. Unit 2 remains in Mode 1, 100% power and stable. There were no actual operational impacts to either unit."

The licensee has notified the NRC Resident Inspector.

* * * RETRACTION FROM BRUCE BUCH TO DANIEL MILLS AT 1428 EST ON 1/30/2014 * * *

"Sequoyah Nuclear Plant, Units 1 and 2, are retracting the 8 hour non-emergency notification made on October 27, 2013 at 2229 EDT (EN# 49476).

"The notification on October 27, 2013, reported that if the service air line (associated with penetration X-108) had ruptured, the additional air into the Unit 1 containment could have exceeded the capacity of the Auxiliary Building Gas Treatment System (ABGTS) and potentially have impacted both trains of ABGTS from performing its safety function(s).

"Subsequent engineering analysis concluded acceptable margin was available. Both trains of ABGTS would have remained operable and capable of performing its design function(s) at all times. The engineering analysis results are captured in the licensee's corrective action program. Based on the new analysis, the condition reported in EN #49476 did not result in a potential uncontrolled radioactive release. This event report is being retracted.

"The NRC Resident Inspector has been briefed on the analysis results and informed of this retraction."

LOST GENERAL LICENSE DEVICE CONTAINING A NICKEL 63 SOURCE

"On January 20, 2012, leak tests were conducted on all [Air Force] BE's [Bioenvironmental Engineering] APDs [air particulate detectors] with the expectation of disposing them to AFRRAD [Air Force Radioactive Recycling and Disposal]. The APDs were placed in storage at the BE office (Bldg. 3423) awaiting sample results and direction from AFRRAD. At the time, AFRRAD had a backlog in workload and were not receiving GLDs [general license devices]. During a GLD program review on Oct.17, 2013, BE determined that the GLD, a Smith's Detection APD-2000 (ECN: 0300069, SN: 4150) was missing and likely disposed via DRMO [Defense Reutilization and Marketing Office]. A records search commenced immediately.

"In April 2013, a SSgt [Staff Sergeant] at 779 AMDS/SGPB began the equipment turn-in process on a GLD, a Smith's Detection APD-2000 (ECN: 0300069, SN: 4150). The GLD was turned over to 779 MDSS/MERC by another SSgt, via AF Form 601 and radiation leak sampling data for the item. Upon receipt of the GLD, MERC then turned it over to 779 MDSS/SGSM. On April 24, 2013, the GLD was removed from the BE Flight's Defense Medical Logistics Standard Support (DMLSS) account, and identified for 'turn-in to DRMO'.

"The SSgt [at 779 AMDS/SGPB], contacted the Defense Logistics Agency (DLA) warehouse at Ft. Meade on Oct. 23, 2013 [and] visited them in an effort to retrieve the missing GLD. DLA [Defense Logistics Agency] records management was overhauled shortly after the item was turned in, thus records relating to the GLD from the warehouse were unable to be furnished. Bioenvironmental Engineering's radiation detection equipment, a SAM940 & Victoreen 451P, were used but [the search] was unsuccessful in locating the GLD at the warehouse. DLA warehouse management has been instructed to immediately notify 779 AMDS/SGPB should the GLD be discovered at their location."

The licensee considers the device un-retrievable and has contacted NRC R4 (Cook).

* * * UPDATE FROM MAJ. DANIEL SHAW TO HOWIE CROUCH AT 1229 EST ON 1/30/14 VIA EMAIL * * *

"The missing ADP-2000 reported (Incident report 49483) has been located by the installation RSO at Andrews, AFB, MD. The source was located [approximately 1/20/2014]. The item has been secured and will be turned in for proper disposal as radioactive waste.

"Note: No leakage or physical damage to the device was noted. No personnel were exposed as the device contains an embedded Ni-63 source with low energy beta emissions.

"Background: The subject device was turned into the Defense Reutilization Management Office (DRMO). DRMO realized that the device contained radioactive material and returned the device to the owning organization.

"Device specifications: Model APD-2000, serial no. 4150, 10 mCi, Ni-63."

The licensee has notified NRC Region 4. Notified R4DO (O'Keefe) and FSME Events Resource (via email).


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.

ABGTS POTENTIALLY INOPERABLE FOR BOTH UNITS UNDER WORST-CASE CONDITIONS

"At 1500 EST on 01/03/2014, TVA determined that during certain conditions, Service Air usage (air used for non-safety related tools/equipment) could result in introducing air into the Auxiliary Building Secondary Containment Enclosure that could, in worst-case conditions, exceed the margin required to maintain the Auxiliary Building Gas Treatment System (ABGTS) operable for Sequoyah Units 1 and 2. ABGTS is required to be operable for both units by Technical Specifications. This is an unanalyzed condition that could prevent both trains of ABGTS from performing [their] safety function[s]. Service air has been isolated to the Auxiliary Building and is under administrative controls until further analysis [is] complete. This is additional information discovered during follow-up evaluation regarding the issue identified in LER 50-327/2013-004. Further analysis will be performed to determine safety significance."

There is 1600 scfm margin in the ABSGTS. The Service Air compressors have an 1850 scfm capacity.

The licensee informed the NRC Resident Inspector.

"Sequoyah Nuclear Plant, Units 1 and 2, are retracting the 8 hour non-emergency notification January 3, 2014 at 2207 EST (EN# 49690).

"The notification on January 3, 2014, reported under certain conditions, service air usage could result in the Auxiliary Building Secondary Containment Enclosure (ABSCE), in worst case conditions, exceeding the margin required to maintain the Auxiliary Building Gas Treatment System (ABGTS) operable and prevent both trains of ABGTS from performing its safety function(s).

"Subsequent engineering analysis concluded acceptable margin was available. Both trains of ABGTS would have remained operable and capable of performing its design function(s) at all times. The engineering analysis results are captured in the licensee's corrective action program. Based on the new analysis, the condition reported in EN #49690 did not result in an unanalyzed condition that significantly degraded plant safety. This event report is being retracted.

AGREEMENT STATE REPORT - LOST GENERAL LICENSED DEVICE

The following information was received from the Commonwealth of Virginia by email:

"Event description: On January 20th the Radioactive Materials Program (RMP) received a call from Simms Metal Recycling in Petersburg, that a load of scrap metal being received set off the radiation monitoring detector. A DOT exemption form was completed and the scrap load returned C&C Cullet, Inc. in Ashland, where it originated from. They dumped the scrap load and found the item using a survey meter, which indicated 87 microrem/hr. Pictures were sent to the RMP and upon review concluded that the device was a liquid scintillation analyzer. The RMP contacted the manufacturer, Perkin Elmer, and began a conversation regarding the analyzer. The analyzer is secured at C&C Cullet, Inc. as an investigation is ongoing to determine the serial number and owner of the analyzer. It is believed to contain an 18 mCi source of either Ba-133 or Ni-63. There are no health or safety impacts as the source is secured in the analyzer."

TEXAS AGREEMENT STATE REPORT - POTENTIAL OVEREXPOSURE TO RADIOLOGICAL WORKER

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

"On January 22, 2014, the Agency [Texas Department of Health] was notified by the licensee's Radiation Safety Officer that they had received a report from their dosimetry processor indicating one of their employees had received 11.27 rem DDE [Deep-Dose Equivalent] on their OSL [optically stimulated luminescence] dosimeter for the exposure period of December 1, 2013 to December 31, 2013. This brought the individuals exposure for the year 2013 to 14.250 rem DDE. The RSO stated they had interviewed the employee, who is a radiography trainee, and was not able to discredit the exposure. The radiographer trainer the trainee worked with was also interviewed and did not have an explanation for the exposure. The trainee has been removed from all duties requiring exposure to radiation. The RSO stated they will contact the Radiation Emergency Assistance Center/Training Site, (REAC/TS) the morning of January 23, 2014, to have a cytogenetic blood testing performed of the individual.

"The RSO stated the trainee's exposure total for the same exposure period, as measured by their self-reading dosimeter, was 165 millirem. The RSO stated the trainee had not been involved in any reported source recoveries or misconnects. The RSO stated they had not observed any medical conditions that would support the reported exposure. The RSO does not believe the exposure is real, but since he has not identified another explanation for the reading he will treat it as real until proven otherwise. Additional information will be provided as it is receive in accordance with SA-300."
