The National Nuclear Security Administration is seeking a new federal project director for the Mixed Oxide Fuel Fabrication Facility under construction at the Savannah River Site in the face of the upcoming retirement of current project chief Clay Ramsey in late August. The NNSA has posted a job opening announcement seeking candidates to manage the plant under construction at the Savannah River Site, which is a critical piece of the agency’s plans to dispose of surplus plutonium. The job opening comes as the MOX facility is undergoing an evaluation that is expected to result in significant cost increases. “Project phases are affected by emerging technical and design issues, changing stakeholder interests, difficulties in forecasting resource requirements, and complex technical factors often lacking precedents,” the job posting states. Responses are due July 17. Ramsey, who has worked at MOX since 2006, is retiring after a “very successful career with NNSA,” spokeswoman Courtney Greenwald said in a written response. “We are conducting a full and open search and are working to fill the position expeditiously as the project is an important part of NNSA’s nonproliferation mission.”
