Licensee,
Georgia Pacific Toledo, notified the Agency [Oregon Department of Health and Radiation Protection] that the 6 month inspection on their K-Ray fixed
gauge (model 7062B) revealed the shutter would not close correctly. The
gauge was still able to perform it's function as a level indicator on a coal bin. Licensee called the manufacturer for repairs. Source is 50 mCi of
Cs-137.
Incident Report # 10-0005
- * * UPDATE FROM DARYL LEON TO VINCE KLCO ON 3/3/10 AT 1154 EST* * *
On February 10, 2010 the licensee's RSO (Radiation Safety Officer) and the vendor technician verified the fixed gauge shutter functioned correctly. It was observed that the time constant on the detector was quite long. The RSO and the vendor determined that the initial report of a shutter malfunction was in error because personnel did not wait long enough to see the result of closing the shutter on the control system.
The licensee will add a note to the inventory form for this source as to the name of the control tag for the detector in order to verify the closed/open shutter transition and to see an adequate response.
No other action is required on this incident and the State of Oregon recommends that that the incident be closed.
Notified the R4DO (Cain) and
FSME (McIntosh).
