The Crystal River Nuclear Power Plant, Unit 3, is part of a 4,700 acre energy complex that contains a 914 MW pressurized water reactor. When the client planned rigging operations for replacement of a steam generator at Unit 3, they required an assessment of potential damage to buried structures in the event of an accidental drop of the components. They also needed to determine safe lifting load paths to avoid failure of the water cooling system in operation during the replacement. SGH analyzed risks and modified lifting load paths to help mitigate damage.
