| ENS 49855 | 23 February 2014 05:00:00 | Agreement State | Agreement State Report - Shutter Failure on Berthold Density Gauge | 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 | ||
| ENS 48707 | 14 January 2013 05:00:00 | Agreement State | Agreement State Report - Shutter Failure | The following was received from the Commonwealth of Pennsylvania via facsimile: On January 15, 2013, the licensee sent notification via email to the Central Office (PA Bureau of Radiation Protection) about an event that took place on January 14, 2013. This email was received by Central Office (PA Bureau of Radiation Protection) on January 16, 2013. It is reportable within 24 hours under 10CFR30.50(b)(2). During use of the gauge, the density readings were not as anticipated. The electronic technicians replaced the detector with no change in output. Based on the output readings, the suspicion is that the shutter is closed and cannot be opened. The gauge has been taken out of service and stored securely in their Meadville Warehouse. The device is identified as: Manufacturer: Berthold Technologies USA, LLC Model: LB 8010 Serial #: 10185 Source Serial #: 1160/10 Isotope: Cs-137 Activity: 20 mCi The manufacturer is being contacted to investigate and perform repairs if needed. A reactive inspection will be performed by the Department (PA Bureau of Radiation Protection). Event Report No: PA 130002 | ||
| ENS 48324 | 18 September 2012 04:00:00 | Agreement State | Agreement State Report - Shutter Failure | The following information was provided by the State of Pennsylvania via facsimile: On September 19, 2012, the licensee sent notification via email to the Department's Central Office regarding an event that took place on September 18, 2012. The event is reportable within 24 hours per 10CFR 30.50(b)(2). The licensee discovered during a routine maintenance inspection that the pin which allows the shutter handle to move was stuck in the closed position, rendering the shutter inoperable. No radiation exposure to personnel is believed to have occurred. The cause of the event was normal wear of gauge. The handle is in the closed position and the gauge has been taken out of service. A reactive inspection is planned by the Department's Western Regional Office. The device is identified as: Manufacturer: Berthold Technologies USA, LLC Model: LB8010 Serial #: 10055 Isotope: Cs-137 Activity: 20 mCi Source Serial Number: 0800/08 Event Report ID No: PA120031 | ||
| ENS 47601 | 16 December 2011 13:00:00 | Agreement State | Agreement State Report - Shutter Failure on Berthold Technologies Detector | The following report was received via facsimile from the PA Department of Radiation Protection. Notifications: On Friday January 13, 2012, the licensee sent notification via email after close of business, to the central office about an event that took place on March 18, 2011. This email was received by central office on Tuesday January 17, 2012. It is reportable within 24 hours under 10 CFR 30.50(b)(2). Event Description: On March 18, 2011, a service vendor was at Universal Well Services to perform a change of the iron piping. At that time, they noticed an improper functioning shutter mechanism and it was temporarily fixed. On December 16, 2011, the licensee was inspected by Pennsylvania DEP (Dept. of Environmental Protection). It was found that the shutter on the Berthold Technologies Detector, Serial Number 10072 had been replaced on December 15, 2011 with a new shutter Serial Number 10275, permanently fixing the shutter failure. The device is identified as: Manufacturer: Berthold Technologies USA, LLC; Serial #: 10072 (becoming 10275); Isotope: Cs-137; Activity: 20 mCi. CAUSE OF THE EVENT: Excessive build-up of debris ACTIONS: The licensee was directed to make the required notification immediately after receiving an NOV (Notice of Violation) from Pennsylvania DEP dated January 13, 2012 about the shutter failure discovered during an inspection on December 16, 2011.

| ENS 47602 | 21 November 2011 13:00:00 | Agreement State | Agreement State Report - Shutter Handle Failure on Berthold Technologies Density Gauge | The following report was received via facsimile from the PA Department of Radiation Protection. Notifications: On Friday January 13, 2012, the licensee sent notification via email after close of business to the central office about an event that took place on approximately November 21, 2011. This email was received by central office on Tuesday, January 17, 2012. It is reportable within 24 hours under 10 CFR 30.50(b)(2). Event Description: It was noticed during a job on approximately November 21, 2011, the shutter handle of Berthold Technologies density gauge, Serial Number 10049, had fallen off due to constant vibration and cavitation of the iron piping on the truck. This caused the roll pin that secures the rotary shutter handle to the shutter shaft to wear and eventually fall off. The gauge was temporarily repaired in the field, and reported on November 29, 2011 to the company's safety officer. The gauge was immediately taken out of service and scheduled for repair. The device is identified as: Manufacturer: Berthold Technologies USA, LLC; Model: LB8010; Serial #: 10049; Isotope: Cs-137; Activity: 20 mCi. CAUSE OF THE EVENT: Excessive vibration of the equipment. ACTIONS: On December 1, 2011 repairs were made to Serial Number 10049. For preventative maintenance, the roll pin was replaced on Serial Number 10055 as well. Event Report ID No.: PA110042 |
