NRC NOV – NOV (White)

On November 1, 2023, the NRC issued a notice of violation associated with a white significance determination process finding to Energy Northwest (licensee) at the Columbia Generating Station. The white finding, an issue of low-to-moderate safety significance, involved the licensee’s failure to take suitable and timely measurements to adequately assess the internal dose of two pipefitters after a reactor water cleanup contamination event. This failure resulted in a violation of Title 10 of the Code of Federal Regulations 20.1204 "Determination of internal exposure."
