NAC-STC SAR March 2017 Docket No. 71-9235 Revision 18 The CY-MPC Failed Rod Storage Canister, shown in Figure 1.2-6, is similar in design to the CY-MPC Reconfigured Fuel Assembly but holds only a maximum of 60 fuel rods classified as failed in stainless steel tubes.

Some of the Connecticut Yankee fuel assemblies will be stored with flow mixers, reactor control cluster assemblies (RCCA) or stainless steel rods installed. Flow mixers are thimble plug assemblies used during reactor operation to maintain equal coolant flow in fuel assemblies that do not contain a reactor control cluster. Reactor control clusters were used to control the reactivity of the Connecticut Yankee reactor during operations and shutdown. Some Connecticut Yankee fuel assemblies may have missing fuel rods and/or may have solid filler rods replacing the missing fuel rods.

A maximum of two assemblies with up to two irradiated stainless steel filler rods per assembly may be loaded in the CY-MPC canister. These assemblies may only be loaded in the two central basket positions.

In the HLW overpack configuration, two stainless steel spacers, one placed below and one above the HLW overpack, are used to position the HLW overpack so that the location of the center of gravity of the packaging is the same as it is for the uncanistered fuel packaging. The HLW overpack shell, bottom, and welded closure lid are fabricated from stainless steel. The basket for the HLW canister configuration is an assembly of five vertical cylindrical cells, each designed to accommodate a welded HLW canister, a melter-evacuated canister (EC) partially filled with glass, or an HLW debris canister.

Two impact limiter designs consisting of a combination of redwood and balsa wood, encased in Type 304 stainless steel, are provided to limit the g-loads acting on the cask during a drop accident load condition. The g-loads are limited by the crush strength of the wood contained in the impact limiters. The predominately balsa wood impact limiter (the balsa impact limiter) is designed for use with all the proposed contents. The predominately redwood impact limiters (the redwood impact limiter) may only be used with directly loaded fuel or the Yankee-MPC configurations.

Any number of NAC-STCs may be shipped at one time, with each cask on its own railcar. The NAC-STC may also be shipped in any number on board ships, barges, or special heavy-haul vehicles.
