"At 0856 EDT on October 22, 2018, it was discovered that the Control Room Envelope, a single-train system, was inoperable due to failure of a boundary door to latch; therefore, this condition is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(v)(D) as a loss of safety function. The door latch was repaired, and the Control Room Envelope declared operable at 0910 EDT.
"There was no impact on the health and safety of the public or plant personnel, as the door was capable of being closed at all times and the door was manned the entire time it could not latch.
"The NRC Resident Inspector has been notified."

"Retraction of Event #53685, Control Room Envelope Declared Inoperable due to Door Latch Failure
"Based on subsequent field measurements taken for the boundary door, the force needed to open the unlatched door is sufficient to maintain the Control Room Envelope positive pressure. Therefore, the Control Room Envelope remained Operable with the boundary door unlatched, and this issue did not prevent the system from fulfilling its safety function to mitigate the consequences of an accident.
"The NRC Resident Inspector has been notified."

The following was received via email:
"Specific Location Information Where Incident Occurred:
Pace Analytical Services, Beaver-WV Environmental Laboratory
"Incident, Amount:
In [Pace's] inventory, [Pace] had six spare Agilent ECDs [Electron Capture Devices]. [Pace] believes they were accidentally placed in the trash for disposal and were subsequently placed in the local landfill. The ECDs have a sealed source with approximately 15 milliCuries of Nickel 63 each. These were the ECDs only and not the entire instrument, Gas Chromatograph (GC).
"ECDs / Models:
F6470 / 19233
F6526 / 19233
L2643 / 19233
L7189 / 19233
F4602 / 19233
F6242 / 19233
"Date of Lost/Misplaced ECDs, Last Time Seen:
Identified as missing October 1, 2018.
Confirmed to be missing October 3, 2018
Last seen September 26, 2018.
Believed to be placed in the laboratory trash September 26th-29th, 2018.
"Root Cause:
During a clean-up/lean event employees were going through the lab and reorganizing/disposing of unneeded materials. The six ECDs were used as reserves for GC instrumentation and placed in a bag in efforts to not dispose of them. At some point later in the week, it is believed that either an employee or cleaning person mistook the bag as garbage and threw them away.
"Measures to Recover:
Upon discovering the lost ECDs, Pace contacted the trash hauler - Raleigh County Solid Waste Authority. They stated that, due to the length of time that has passed since disposal, the likelihood of recovery is essentially zero. Due to the process of filling hollow-like areas, anything disposed has approximately 20 feet of additional material over it, and they have no way of knowing where the truck would have dumped the materials."
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.

The following information was obtained from the State of Tennessee via email:
"On 10/31/18, the Tennessee Division of Radiological Health was contacted via phone by Ludlum Measurements RSO regarding the loss of a licensed source. It appears the source was last seen on 8/10/18. The licensee realized the source was missing on 8/13/18. The licensee has been searching for the source from 8/13/18 to date. The whereabouts of the source are still unknown at this time.

NMSS_EVENTS_NOTIFICATION (EMAIL) | Event Text AGREEMENT STATE REPORT - LEVEL GAUGE SHUTTER MALFUNCTION
The following was reported by the Louisiana Department of Environmental Quality via email:
"On 10/31/2018, Eagle US 2 was performing their semiannual inventory and operational checks of their RAM [radioactive material] licensed devices. During their routine semiannual maintenance checks, the shutter malfunction was discovered. The gauge shutter would not close due to a shutter pin sheer.
"Eagle US 2 called a service contractor, BBP Sales, [to] perform the semiannual checks. BBP Sales is evaluating the situation to determine the best course of action to correct the problem. [The contractor] was unable to close the shutter and will determine the course of corrective action. It appears the corrective action will be to replace the device. The cause appears to be the conditions of a corrosive environment where the gauge is installed and used.
"The sources and device with a broken shutter pin and shutter stuck open will remain installed and utilized on the process until the repairs are made. This is not a radiation exposure hazard and does not pose a health and safety situation for the Eagle US 2 employees or the general public.
"The Gauge is a RONAN SA1-C-10 device/source holder, S/N 5977-GK, loaded with a 5 mCi Cs-137 source."

ELIZABETH REED (NPR) | Event Text TECHNICAL SPECIFICATION VIOLATION - UNSECURED REACTOR LEFT UNATTENDED
The following is a synopsis of a notification received from Reed College:
The licensee made an official notification of a violation of technical specification (TS) 6.1.3 a 1 as well as TS 1, which defines the reactor as operating when it is not shutdown or secured. The Reactor Operator (RO) left the control room for approximately 30 seconds while the reactor was subcritical but not secured. Per the TS definition, the reactor is not secured if the reactor console key is in the console. The RO immediately returned to the control room and removed the key and ensured the reactor scrammed.
The Senior Reactor Operator (SRO) was in the next room and was informed. Another SRO was in the control room but was not requalified. | |
