NRC CAL – NOV (Yellow & White)

On April 19, 2010, a Notice of Violations was issued to Tennessee Valley Authority (TVA) for violations associated with Yellow and White Significance Determination Findings as a result of inspections at the Browns Ferry Nuclear Plant. The Yellow finding involved the licensee's failure to meet the requirements of 10 CFR 50, Appendix R, III.G, fire protection of safe shutdown capability. There were multiple examples of the licensee not providing fire protection features capable of limiting fire damage and failing to ensure one train of systems or components was free of fire damage by approved methods. Compensatory measures are currently in place and long term corrective actions will be implemented. The White finding involved the licensee's failure to meet the requirements of a Technical Specification. This involved the inappropriate revision to a procedure which could have delayed proper operator response to a major disabling fire event. The procedure has been revised to prevent such an issue from occurring.
