On December 4, 2008, a Notice of Violation was issued for a Severity Level III violation. The violation involved the failure to use a minimum of two independent physical controls that form tangible barriers to secure a portable gauge whenever the gauge was not under the control and constant surveillance of the licensee as required in 10 CFR 30.34(i). Specifically, the licensee stored portable gauges at two separate locations on campus using only one independent physical control that formed a tangible barrier to prevent unauthorized removal of the gauges when not under the control and constant surveillance of the licensee.
