Title | Commercial Grade Dedication Program Degraded |
Event Description | WBN [Watts Bar Nuclear] Unit 2 (under construction) has determined that certain equipment components have been installed that may not meet the requirements of the commercial grade dedication process. This condition has the potential to create a substantial safety hazard had it remained uncorrected. Evaluations are being performed to determine if the installed equipment would have still performed their safety functions. No specific cases of a substantial safety hazard have been found to date, but until evaluations are completed, the safety significance of this condition remains indeterminate. Therefore, this condition is conservatively being reported by WBN Unit 2 under 10 CFR 50.55(e).
This programmatic issue encompasses approximately 500 evaluations. The licensee will contact the NRC Resident Inspector. |
