| Title | Part 21 - Contactor Making Noise |
| Event Description | The following was received via fax:
Initial notification of a potential 10 CFR Part 21 condition. Pursuant to the rules of 10 CFR 21.21 this initial notification is being submitted to the NRC to identify a potential reportable condition that is currently under evaluation. FPL [Florida Power & Light] Turkey Point has identified a contactor that was making a considerable amount of noise that was not expected. The unit was continuing to functionally operate, however the source of the noise is cause for investigation. The contactors are a non-standard Size 3 and Size 4 Freedom Series Starter/Contactor. These units are currently under evaluation and review by NLI [Nuclear Logistics Inc.] to determine the root cause of the identified condition to determine if the contactor contains a defect. To date there have been no reported failures of this item to perform the intended safety function. These components were first supplied in September 2002 to Duke Oconee with no reported issues identified. The units reported by FPL Turkey point were supplied in May and December 2011. They have been installed into other facilities including the Duke Shearon Harris plant in December 2013. Although the increased noise is undesirable, it is not presenting a significant condition adverse to quality that could create a substantial safety hazard. Preliminary testing has confirmed that the safety related performance characteristics have not been degraded. However, due to the number of utilities which may have these components in service, this notification is being submitted to identify the condition to the industry. NLI plans to have the completed report submitted by 3/15/2016.
This retraction is a brief summary from a report received from Nuclear Logistics Inc. via email: This retraction is being submitted to the NRC to provide additional information for the initial notification provided on 2/18/2016. After evaluating the identified condition, it has determined that there is no defect within the contactor that if left uncorrected would create a substantial safety hazard. This issue is not considered reportable per the rules of 10 CFR Part 21. Notified R1DO (Ferdas), R2DO (Shaeffer), R3DO (Stone), R4DO (Whitten), and Part 21/50.55 Reactors via email. |
