Researches, plans, designs and develops mechanical products and systems such as instruments, controls, robots, engines, machines and mechanical, thermal hydraulic or heat transfer systems for production, transmission, measurement, and use of energy. Applies research to the planning, design, development, and testing of mechanical and/or electromechanical systems, instruments, controls, engines, and/or machines. This position is for an experienced mechanical engineer in the A4W Reactor Plant Planning Yard (Department E83). The successful applicant will be responsible for conducting and leading engineering efforts associated with the inactivation/disposal of CVN68 Class carriers. This includes development and application of governing specifications, various engineering studies, and interfacing with multiple disciplines, organizations, and the government to support efficient and effective planning and execution of inactivation efforts. Specific task areas include residual water determinations, review and update of inactivation guidelines, dismantlement studies, shipboard technical support, equipment reutilization management, and environmental impact studies. The incumbent will be capable of performing engineering calculations, analyses, cost benefit analysis, risk assessments and studies to support planning decisions. Shipboard visits may be necessary for problem resolution and may involve access to radiological areas. A working understanding of reactor plant systems and governing design documents is needed as well as a familiarization with Propulsion Plant systems.
