UNPLANNED CONTAMINATION EVENT
"On July 11, 2018, at approximately 0645 [EDT] a radiological spill occurred in Building 333 Uranium Metal Dissolution area due to a glass column leak. This area is controlled as a Radiologically controlled Area. Cleanup and evaluation activities were initiated, but later suspended when it was determined the column had failed and additional evaluation for structural stability was necessary prior to safely performing additional recovery and decontamination activities.
"There were no radiological or chemical exposures. There were no releases to the environment or public areas.
"The licensee has notified the NRC Resident Inspector."

METEOROLOGICAL DATA UNAVAILABLE
"On July 11, 2018, as part of pre-planned maintenance, the site meteorological tower will be removed from service. The tower will be out of service for approximately 11 days. As a result, this is reportable under 10CFR 50.72 (b)(3)(xiii). During the time the data is not available from the meteorological tower; compensatory measures will be in place to obtain the data from the National Weather Service if necessary.
