Event Notification Report for December 05, 2016

AGREEMENT STATE REPORT - TWO LOST Po-210 IONIZERS

The following was received from the New York State Department of Health (NYSDOH) via fax:

"NYSDOH was notified in writing by an administrator for Emagin Corporation on December 18, 2019 (letter dated December 5, 2019), that two Nuclecel In-Line Ionizers had been lost and unable to be located at the licensee's facility in Hopewell Junction, New York.

"These two devices are NRD, LLC P-2021 ionizers. Both devices contain sealed Po-210 sources with 10 mCi per device (assayed at the time of production). The device serial numbers are A2JY966 with source s/n 057171, and A2HM243 with source s/n 047955. Both sources are believed to be decayed down to greater than 14 half-lives to date.

"According to the licensee, these sources were identified as lost during periodic housecleaning of their facility clean room approximately three years ago. The licensee attempted to locate the devices at that time and continues to attempt to locate the devices. The licensee also states that NRD, LLC verified that the devices in question were not returned to their facility.

"NYSDOH will continue to monitor this incident under NYSDOH Incident No. 1312. The licensee will be providing additional information on the event, corrective actions, and steps to prevent recurrence in the future."

EVENT REPORT ID NO.: NY-19-11

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.

PART 21 - NON-CONFORMING COVER MACHINING ON SOLENOID VALVE

The following is a synopsis of the Part 21 report that was received via fax:

"Cover Machining is installed on upper section of Solenoid Valve and it allows for the electrical connection to the valve solenoid and protects inside wiring of the solenoid from environmental condition. Cover machining part number V52636-567 has 0.190 radius (Drawing V52620-50 Zone D3) which was machined too deep removing material from surface needed for proper O-ring seal. The lack of material exposes part of the sealing O-ring which could diminish the O-ring sealing capability. With O-ring sealing capability diminished, Valcor cannot ensure that valves with Cover Machining Installed on Solenoid Assembly will perform its safety function during all postulated events.

"This item has historically been manufactured by machining a casting. For the lot involved, castings were not available. Authorization was given to manufacture the Cover directly from suitable bar stock. To accomplish this, Valcor's vendor used the casting drawing and casting machining drawing to manufacture the finished machined part. The combination of these two drawings had insufficient control on the corner radius, resulting in this nonconformance.

"All defective covers in stock have been quarantined and a nonconformance report has been generated. Lack of location controlling dimension on the Cover Machining drawing for 0.190 radius was discovered to be the root cause of the defect. Valcor has created and released a new engineering drawing that properly controls the location of 0.190 radius. This action has been completed as of 11/22/2016. Engineering Manager-Nuclear was responsible to this action.

"Valcor is in a process of notifying all affected customers.

"Customers:
Ameren, Valve Part Number V526-6000-16 (Stock# 7731643), S/N 9, QTY 1, Location Ameren Missouri - Callaway
Bruce Power (BPC), Valve Part Number V526-6000-20 (Cat ID 142129), S/N 28-36, QTY 9, Bruce NGS

"Note: All 9 valves supplied to BPC have been returned to Valcor for nameplate correction and are accounted for.

"If you have any questions or addition information is needed regarding this matter, please contact Fran Lucano at 973-467-8400."

FITNESS FOR DUTY

"A non-licensed supervisory employee had a confirmed positive for a prohibited substance during a random fitness-for-duty test. The individual's unescorted access to the plant has been denied.

"The licensee has notified the NRC Resident Inspector."
