On October 27, 2009, the NRC issued a Notice of Violation for a Severity Level III violation to Northern States Power Company, Minnesota. The licensee violated 10 CFR 50.9 which requires, in part, that information provided to the Commission by an applicant shall be complete and accurate in all material respects. Specifically, on May 11, 2007, the licensee failed to report a medical condition, as required by 10 CFR 55.23 "Certification," of a senior reactor operator (SRO) on a license renewal form. This resulted in the NRC renewing the SRO's license without a restriction for the medical condition.
