On July 10, 2006, a Notice of Violation was issued for a Severity Level III problem involving the failure to develop written procedures to provide high confidence that each administration was in accordance with a written directive. Specifically, the licensee's written procedure for high dose rate (HDR) brachytherapy did not describe that the HDR metal interface connector was to be attached during treatment simulation to determine appropriate location of the sources within the patient. In addition the licensee did not notify the NRC Operations Center by the next calendar day following discovery of the medical event.
