The following information was obtained from the state of Mississippi via email:
"Licensee reported a stuck shutter on an Ohmart/VEGA Model SH-F1 level gauge, during semi-annual checks of shutter operation. The failure was identified on 05/17/2016 by the licensee and was immediately reported to RSO. The RSO supposes stuck shutter failure was caused by age and oxidation. Licensee has contacted the manufacturer, Ohmart, for repair of shutter mechanism. Gauge remains in its normal operating position.

PART 70 APP A (a)(4) - ALL SAFETY ITEMS UNAVAILABLE

| Event Text DEGRADED SAFETY ITEMS CAUSED BY URANIUM BUILDUP
"On July 13, 2016, it was determined by the Environment, Health and Safety (EH&S) department that scrubber clean-out material, found in the S-1030 scrubber transition section during the annual maintenance shutdown that occurred in late May, potentially exceeded the uranium mass limit for the scrubber transition.
"(IROFS [Items Relied on for Safety] VENT-S1030-110) requires annual inspection and removal of significant solids buildup in the transition section. Upon inspection, significant buildup was found, and the ductwork was opened to permit extensive cleanout. 36 containers of material with a total gross weight of 210.4 kg was removed from the inlet transition during the cleanout on May 28th to May 29th. Grab samples were subsequently taken from each container and analyzed for uranium concentration. On July 13th, the EH&S department was made aware that the grab sample results averaged 47.8% U. Although the exact uranium mass cannot be determined until the material is dissolved and representatively sampled, available evidence suggests that the mass limit of 29 kg U in the inlet transition was exceeded. The 29 kg U limit is based on an optimally moderated, fully reflected spherical geometry which very conservatively bounds the conditions in the inlet transition of the scrubber. IROFS remained to limit the quantity of uranium available to the scrubber (IROFS VENT-S1030-101, -102, -103 & -104), which are physical barriers designed to minimize uranium in the airflow entering the transition area. Continuous liquid spraying in the inlet transition section to limit solids accumulation (IROFS VENT-S1030-109) was also in place.
"The inlet transition and scrubber were thoroughly cleaned, and the uranium bearing solids were placed into favorable geometry containers. Also, the inspection and cleanout of the transition frequency was increased to monthly.
"Based on available but degraded IROFS, this accident sequence was unlikely. Therefore, this mass accident sequence does not meet the performance requirements of 10CFR70.61. The actual configuration remained safe at all times. Also, no external conditions affected the event.
"Immediate Corrective Actions:
NRC Region II personnel, who were onsite at the CFFF [Columbia Fuel Fabrication Facility], were made aware of the discovery.
"The Conversion area was shutdown to plan for a second extensive scrubber clean-out to validate that the accumulation of solids is a slow buildup over time. The last extensive cleanout was performed in 2009.
"An extent of condition was performed to determine if other scrubbers potentially had significant uranium buildup. Inspection data indicated that this material accumulation issue was limited to the S-1030 scrubber.
"This event has been entered into the facility Corrective Action Prevention And Learning system (CAPAL) #100397353."
* * * UPDATE PROVIDED BY NANCY PARR TO JEFF ROTTON AT 1025 EDT ON 07/26/2016 * * *
"Onsite chemical analysis confirmed that uranium mass limit for the scrubber transition piece was exceeded. The accumulated material contained 87 kgs of Uranium.
"The Criticality Safety Evaluation for this system was revised and implemented on July 20, 2016 to add Items Relied on For Safety to prevent recurrence of a mass exceedance while the causal analysis and additional corrective actions are completed."
Notified R2DO (Nease) and NMSS Events Notification Group via email.
* * * UPDATE PROVIDED BY NANCY PARR TO HOWIE CROUCH AT 1749 EDT ON 07/31/2016 * * *
"On July 31, 2016, it was determined by the Environment, Health and Safety (EH&S) department that clean-out material found in the S-1030 scrubber packing and floor also potentially exceeded the uranium mass limit for the scrubber criticality safety evaluation. Over years of operations, the same available but degraded mass prevention and inspection/clean-out IROFS did not prevent exceedance of the mass limit.
"This report is being upgraded to a 1 Hour Event Notification based on 10CFR70 Appendix A(a)(4).
"There was no consequence to the public, the workers or the environment.
"The scrubber process will remain in a safe shutdown mode until further investigation and corrective actions are completed."

The following was received via email:
"The licensee (QSA Global, Inc.) made telephone notification at 1026 [EDT] on July 22, 2016 followed by written report to the Agency (Massachusetts Radiation Control Program), that the licensee was notified by carrier that one piece of a four piece shipment incoming from Australia and destined for QSA Global, Inc., Burlington, Massachusetts is unaccounted for. The licensee initially identified that it did not know which of the four pieces is the one missing. The licensee provided update by telephone at 1335 on July 22, 2016 that it had determined that the piece missing is a Model 650L source changer, Type B(U) package, UN2916, containing two special form iridium-192 sources, 0.44 TBq (12 curies) total of iridium-192. The missing package is believed by the licensee to possibly be in Memphis, Tennessee at the carrier's hub.
"The licensee reports that it initiated a trace yesterday with the carrier and has also requested a ramp search of the Boston (Logan Airport) facility in case it was separated there.
"The reporting requirement is immediate and is of 105 CMR 120.281(A)(1), missing licensed radioactive materials in aggregate quantity equal to or greater than 1,000 times quantity specified in 105 CMR 120.297, Appendix C.
"The Agency made notification to FBI.
"The Agency considers this event to be open.
"At 1616 [EDT], on July 22, 2016, the licensee (QSA Global, Inc. of Burlington, MA) notified us (Massachusetts Radiation Control Program) by telephone that the missing package has been located by the carrier at its Memphis, Tennessee hub and that the package is expected to be delivered to the licensee on Monday. The licensee reports that a label had apparently fallen off of the package."
THIS MATERIAL EVENT CONTAINS A "CATEGORY 3" LEVEL OF RADIOACTIVE MATERIAL
Category 3 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for some hours. It could possibly - although it is unlikely - be fatal to be close to this amount of unshielded radioactive material for a period of days to weeks. These sources are typically used in practices such as fixed industrial gauges involving high activity sources (for example: level gauges, dredger gauges, conveyor gauges and spinning pipe gauges) and well logging.

The RSO and ARSO, were notified right away and responded immediately to the location. After their assessment, they determined the source pigtail had become detached from the drive cable due to the drive cable ball connector breaking off. There was no other sign of physical damage to the camera, the crank assembly or related equipment. After phone consultation with the manufacturer, a retrieval method was determined and the source was safely secured back into the exposure device.

"On July 30, 2016 at 1152 hours [EDT] following a containment walkdown to investigate an increase in RCS unidentified leakage to 0.15 gpm, a leak was identified on the seal return line from 2-RC-P-1C, 'C' Reactor Coolant Pump. The source of the leakage cannot be isolated and is considered RCS pressure boundary leakage. [Technical Specification] LCO 3.4.13, RCS Operational Leakage, Condition B for the existence of pressure boundary leakage was entered. Technical Requirement TR 3.4.6, ASME Code Class 1, 2, and 3 Components is also applicable. Unit 2 is projected to be taken to Mode 5 for repair.
"This event is reportable in accordance with 10 CFR 50.72(b)(2) for 'the initiation of any nuclear plant shutdown required by the plant's Technical Specifications' and 10 CFR 50.72(b)(3)(ii)(A) for 'any event or condition that results in the condition of the nuclear plant including its principal safety barriers, being seriously degraded.'"
