On February 12, 2020, the NRC issued a Notice of Violation to Bittner Engineering, Inc. (Licensee) for a Severity Level III problem associated with four related violations. The violations involved the licensee’s failure to: (1) have the named individual on its license perform the duties and responsibilities of the Radiation Safety Officer (RSO) as required by License Condition 12 of NRC License 21-26010-01; (2) perform leak tests of sealed sources in accordance with License Condition 13 of NRC License 21-26010-01; (3) perform a review and implementation of radiation safety program as required by Title 10 Code of Federal Regulations (10 CFR) Part 20.1101(c); and (4) provide hazmat employees with the hazmat refresher training as required by 10 CFR 71.5(a). Specifically, the RSO named on the license retired in 2014 and the license was not amended to name a new RSO until May 23, 2019. Additionally, between December 2014 and May 23, 2019, the licensee did not perform the annual leak tests on the portable gauges, did not perform the required review of the radiation safety program, and did not provide the required recurrent training for its hazmat employees.
