| Event Description | EN Revision Text: SAFETY EQUIPMENT FAILURE - STUCK SHUTTER
On September 25, 2019, at approximately 0800 MDT, while preparing to perform electrical maintenance on a density gauge, the shutter on the gauge was found stuck in the open (normal) position. Upon contacting Berthold, the device manufacturer, the licensee was instructed to contact the NRC to make this notification. The source is a Cs-137, 20 mCi source, S/N 846, manufactured in March of 1990. There is no additional exposure to plant personnel or the public due to the position of the shutter. Berthold is scheduled to replace the shield on October 29, 2019.
After discussion with R4 (Bolger), the licensee is retracting this event because the device is a general license device, not a specific license device, which does not meet the reporting requirements described in 10 CFR 30.50(b)(2). Device is a BSI Instrument LB 7400 series gauge. Notified R4DO (Drake) and NMSS Events Notification (email). |
