Decommissioning case studies

Nuclear Power Plant Study

Orano USA partners with Tri Tool to develop a custom engineered solution to remotely sever underwater jet pumpdiffusers in Vermont Yankee nuclear reactor vessel Tri Tool was tasked with assisting with the removal of 20 underwater jet pump diffusers contained in a highly contaminated environment. To safely sever the jet pump diffusers, Tri Tool had to develop a specialty tool that could be lowered down 70 feet underwater and remotely cut each diffuser in half mounted on the OD. Then, Tri Tool had to develop an additional ID mounted machine that could sever the other half of the pump.
