During the refurbishment, shorter bell cranks were installed to mitigate an identified interference. These shorter bell cranks result in a higher force being needed to close the breaker which could result in failure of the pushrods. In the event of a pushrod failure, the breaker may not trip when required, resulting in a substantial safety hazard.</br>Framatome has provided written correspondence to ANO to advise on this issue.</br>Model: 5-3AF-GEU-350-1200 Breaker</br>Affected plants: Arkansas Nuclear One</br>Gayle Elliott</br>Director, Licensing Regulatory Affairs</br>Framatome Inc.</br>gayle.elliott@framatome.comFramatome Inc. gayle.elliott@framatome.com  +
