SNF Movement transports fuel assemblies between basins. SNF Packaging are operations to crop, as required, fuel assemblies and place them into bundles. SNF Storage involves tasks of selecting the approved storage positions and loading the bundles into the racks. These processes are of particular concern to nuclear criticality safety. Heavily shielded casks transport SNF assemblies to and from the basin facilities.
Overhead cranes transfer the casks between the cask handling basins and the rail or truck cars.
Procedures are customized based upon the fuel specific NSDS limits and in the case of cask operations, deal primarily with a safe number of assemblies allowed to be handled as a group. Operations, Engineering, and Criticality organizations review and approve the procedures. On arrival at SRS, the cask 's bill of lading is compared to the Appendix A to ensure the designated fuel was received. All further moves of the cask and fuel are then performed per specific operating procedures. The cask is brought into the facility where temperature, contamination, and radiation measurements are taken and evaluated.
