UNPLANNED CONTAMINATION DUE TO KILN SEAL LEAK

"On 11/17/2018, at approximately 1445 EST, it was discovered that the Fuel Manufacturing Operation (FMO) Dry Conversion Line 1 kiln seal began to leak
and caused an alarm on the Hydrogen Fluoride (HF) room detection system.

This manufacturing process equipment is within an established FMO contamination-controlled area which is designed to contain and control this type of release.

The area was not occupied at the time, there were no personnel exposures or releases from the area and the affected process was shut-down.

"As a precautionary measure consistent with current NRC radiation protection requirements,
[ they are following an NRC requirement, yet this statement is inserted to make it seem they are doing this because of concern for the workers. ]
 
an appropriate, additional radiological control was imposed
by requiring respiratory protection for entry into the room to keep personnel exposures as low as reasonably achievable
until the area could be decontaminated in a safe and timely manner.
[ No executives, managers or shareholders will be directly affected by the contamination event, although one executive did have to cancel his Cancun vacation. ]

Although the affected equipment remains shutdown, this additional radiological control remained in place for more than 24 hours.

"NRC Fuel Cycle Safety and Safeguards staff recently clarified its position for this type of reportability determination
in a letter sent to the Nuclear Energy Institute dated October 5, 2018.

Because of this letter, this event is conservatively being reported pursuant to the requirements of 10 CFR 70.50 (b)(1)."
[ If they could have gotten away with it, they wouldn't have notified anyone. ]

The NRC region will be notified.
Additionally, the North Carolina Radiation Protection Commission and New Hanover County Emergency Management will also be notified.



[ This event should not to be confused with normal planned contamination. ]
