Title	Agreement State Report - Stuck Open Shutter on Nuclear Process Gauge
Event Description	The following summary report was received from the North Carolina Radioactive Materials Branch via email: This happened 11/15/19 and [the Nucor Environmental Manager] was made aware of the incident around [1400 EST], yesterday. Nucor Steel has a 2015 fixed nuclear gauge in a c-frame that was due for maintenance. The gauge was deemed offline and they rolled the c-frame to a locked location where they were to perform scheduled maintenance. It was at this time that they discovered the shutter was stuck open. They tried to close the shutter (with air) but it would not close. [The Nucor Environmental Manager] explained that they roll the gauge by motor, and that during this time the shutter was opened. No employee was exposed to radiation. This gauge is exposed to the elements and [the Nucor Environmental Manager] believes there is dirt inhibiting the shutter from closing. Since they could not get it to close, they rolled the gauge back to its normal online position where it can be open and not at risk to employees. [The Nucor Environmental Manager] stated there is no damage to the source and there [are] not any leaks. [The Nucor Environmental Manager] called the manufacturer to come perform maintenance yesterday. They arrived at his facility around [1400] today and are currently working on the gauge.
