Independent Spent Fuel Storage Installation (ISFSI) platform

The ISFSI platform is a crucial asset for nuclear facilities during dry cask campaigns. It enables the safe and efficient handling of spent fuel casks, ensuring compliance with strict safety and operational standards. By providing a stable, adjustable platform that withstands seismic activity and extreme weather, the ISFSI platform supports vital storage and transfer operations. Its modular design assembles safely from the refuel floor or aux building without fall protection or bolted joints, making it an indispensable tool for safety and efficiency during nuclear outages and in ongoing facility operations.
