| Title | Agreement State Report - Shutter Failure on Berthold Density Gauge |
| Event Description | The following information was received from the Commonwealth of Pennsylvania via fax:
NOTIFICATIONS: Licensee notified the Department [PA DEP Bureau of Radiation Protection] via email and voice message after close of business on February 24, 2014. This event is reportable within 24-hours per 10 CFR 30.50(b)(2). EVENT DESCRIPTION: During the pressure pumping operations at a well fracturing job site, personnel observed an unexpected fluctuation in density readings. The density gauge was inspected and attempts to turn the shutter handle to the closed position caused it to separate from the body of the gauge. It was observed that the roll pin, which attaches the shutter handle to the shutter shaft, had come out causing the shutter handle to separate from the shield housing. The pin was replaced, the handle reattached, and the gauge shutter was closed and locked. No elevated exposure to personnel is anticipated. The gauge was then removed from service, placed into storage, and the manufacturer was notified. Manufacturer: Berthold Model: LB 8010 Serial Number: 10049 Isotope: Cs-137 Activity: 20 mCi Source Serial Number: 0180/08 CAUSE OF THE EVENT: The roll pin, which attaches the shutter handle to the shutter shaft, came out causing the shutter handle to be removed from the shield housing. More information will be forwarded upon receipt of final report. ACTIONS: The density gauge has been removed from operations and is in storage in a Williamsport, Pennsylvania facility. The licensee is working with the manufacturer to investigate the event, make repairs, and determine root cause. The Department plans to do a reactive inspection. PA Event Report ID No: PA140006 |
