Dry Cask Simulator (IMAGE) DOE/Sandia National Laboratories Caption Sandia National Laboratories designed and constructed a dry-cask simulator for boiling water reactor assemblies to study how hot spent nuclear fuel will get during storage and how the fuel's peak temperatures affect the integrity of the cask over time. Electrical heaters shaped like fuel rods were used instead of spent nuclear fuel in the otherwise prototypical fuel assembly.
