| Title | Agreement State Report - Nuclear Fixed Gauge Damaged |
| Event Description | {{#Wiki_filter:The following report was provided by the Arkansas Department of Health via email:
Nucor-Yamato Steel Company, Arkansas Radioactive Materials Licensee Number ARK-0722-03120, notified the Arkansas Department of Health, Radioactive Materials Program, via phone on Friday, June 19, 2015, at 1000 [CDT], of damage to one of their fixed gauges, manufacturer Ronan, Model #SA-1-F37, Serial #1224CG with a 5 Curie Cs-137 source. The event occurred on June 18, 2015 at approximately 1230 [CDT]. Licensee reported a wash-out of liquid steel which came into contact with the gauge. There was approximately 30 tons of molten rock (2800 �F) flowing onto the floor of the plant which caused a fire. Surrounding gauges were not affected. The Licensee immediately closed the shutter, but was not sure if it was completely shut. The RSO indicated the only radiation levels were from the top of the gauge, nothing was measured on the sides. A steel plate was placed on top of the gauge to reduce radiation levels. The area was roped-off at 2 mR/hr to prevent public exposures. Chase Environmental Consulting was notified of the damaged gauge and arrived on Friday, June 19, 2015 to investigate and remove the gauge out-of-service. The gauge is currently in storage awaiting the manufacturer (Ronan) to arrive to package for shipment on Friday, June 26, 2015. The State is awaiting a written report from the licensee and will continue to investigate this event. The State will update this event as more information becomes available. Arkansas Event Number: ARK-2015-008
