With a total of 3 patents to his name, Ethridge has developed innovative solutions that enhance the efficiency and safety of core plate structures.
Latest Patents
Ethridge's latest patents include a method and apparatus for repairing a core plate with a cracked support structure. This invention, titled "Core plate repair using guide tube gap wedges," provides a vertical compression load path between the core plate and control rod guide tubes. The method involves installing load-bearing wedges that allow core plate pressure loads to be supported by the weight of the fuel, rather than the core plate support structure. This innovative approach enables the installation of wedges without the need to remove the guide tube or fuel support casting.
Another significant invention by Ethridge is the "Internal bushing removal tool." This tool is designed for the removal of internal bushings from a piston coupling of a control rod drive (CRD). It features a spring-loaded collet that latches onto the internal bushing, allowing for efficient dislodgment by impacting the ram with a hammer.
