AGREEMENT STATE REPORT - DAMAGED KAY-RAY FIXED GAUGES REPAIRED WITH SHUTTER OPEN

The following report was received from the State of Arkansas via email:

"[The licensee] discovered two fixed gauges, manufactured by Kay-Ray, model #GRP-6082, serial #6124 (digester 2) and #6125 (digester 3) with a 5 Curie Cs-137 source were damaged sometime in May 2014.

"The Department [Arkansas Department of Health] became aware of the repair during a routine inspection of the plant. According to the field service report, repairs were performed on June 5, 2014. The repairs were to the lead shielding around source holders which was separated from the original fabrication and needed to be refastened. The field service report indicated the shutter was not closed during the repairs.

"Basic evaluations at the time of inspection, by [licensee] Radiation Control Health Physicists, indicated there were no public exposure levels above the regulatory requirement. The gauges are mounted on a steel metal box. The gauges are located on the 3rd floor 10 feet above the floor. Gauges are in cages inaccessible without a ladder. It is believed a small field of radiation was present but there were no significant exposures to the public.

"The State is awaiting a written report from the licensee and will continue to investigate this event. The State will update this event as more information becomes available.

"Louisiana Department of Environmental Quality office was notified."

Arkansas Event Number: ARK-2015-011

* * * UPDATE FROM SUSAN ELLIOTT TO STEVEN VITTO ON 03/08/2016 AT 0943 EST * * *

The following was received via email:

"The written report dated March 3, 2016, from Clearwater Paper Corporation, detailed corrective actions to ensure repairs to the lead shielding around source holders were sufficient to prevent radiation exposure. A licensed contractor inspected all sources for physical integrity and validated their findings. There was no radiation leakage from any of the fixed gauges to include the two in question. The licensee confirms no exposure to the public.

"The State considers this event closed."

The following Agreement State Report was received from the State of Texas via email:

"On March 1, 2016, the Agency [Texas Department of State Health Services] received notice that on February 29, 2016, the licensee had discovered that a Berthold fixed gauge model MB7442D containing 30 milliCuries of cesium-137 had malfunctioned. The shutter was stuck in the open position. The gauge is normally left in the open position, and no exposure to the public is likely. Additional information will be provided as it is received in accordance with SA-300."

SECONDARY CONTAINMENT DIFFERENTIAL PRESSURE OUTSIDE SPECIFICATION

"On March 8, 2016 at 0232 hours [EST], Secondary Containment Zone 3 (Unit 1&2 Reactor Building) differential pressure lowered to 0.16 inches water gauge when securing Unit 1 Zone 3 HVAC for planned maintenance. Required differential pressure per SR 3.6.4.1.1 could not be maintained in the intended alignment. Zone 3 ventilation was restored to the original alignment and Zone 3 differential pressure recovered to greater than 0.25 inches water gauge at 0335 hours. Zone I (Unit 1 Reactor Building) and Zone II (Unit 2 Reactor Building) ventilation remained in service and stable. Station engineering and maintenance are investigating the Zone 3 HVAC system to determine the cause.

"This event is being reported under 10 CFR 50.72(b)(3)(v)(C) and per the guidance of NUREG 1022, Rev. 3 section 3.2.7 as a loss of a Safety Function. There is no redundant Susquehanna Secondary Containment System."

The NRC Resident Inspector has been notified.
