DNP-TIP-2023-10: Virtual Reality Polar Crane Simulator

The Tennessee Valley Authority (TVA), in partnership with Industrial Training International (ITI), addressed a major challenge in reactor maintenance concerning training for polar crane operation. With polar cranes being nearly unique to the nuclear industry, polar crane operators had few options for practicing their skills. Crane operators could practice a crane operation scenario only during actual lifts. This presented undesirable risks to personnel and plant equipment. To reduce these risks, in 2021 TVA collaborated with ITI to develop a virtual reproduction of the Watts Bar Unit 2 containment area in which the polar crane is used. In this virtual environment, operators can practice specific scenarios including lifts of the reactor head, gates, missile shields, upper and lower internals, core barrel, and reactor coolant pump motors, with zero risk to themselves or vital plant equipment. TVA also found the virtual environment is useful for helping members of the rigging crew to visualize load paths and optimal placement of personnel. The ITI Virtual Reality (VR) Polar Crane Simulator consists of a laptop paired with VR goggles and interchangeable control pods. The control pods simulate the actual controls of the crane that will be used. The simulator can be packed into two Pelican™ cases and is easily transportable between Sequoyah Nuclear Plant and Watts Bar Nuclear Plant.
