2.5 Big Rock Point This section describes the inventory of used nuclear fuel and GTCC low-level radioactive waste, site conditions, near-site transportation infrastructure and experience, and gaps in information for the Big Rock Point site. The Big Rock Point site is located on the eastern shore of Lake Michigan about 4 miles north of Charlevoix and 10 miles west of Petoskey, Michigan (TOPO 1994a). Site Inventory Seven canisters containing 441 used nuclear fuel assemblies and 1 canister of GTCC low-level radioactive waste are stored at the Big Rock Point ISFSI (Docket No. 72-43). The seven canisters contain 50 damaged used nuclear fuel assemblies which have been placed in damaged fuel cans. In addition to uranium dioxide (UO 2 ) used nuclear fuel assemblies, there are 36 mixed oxide used nuclear fuel assemblies stored at Big Rock Point. Table 2-4 lists the assembly identification numbers for these mixed oxide used nuclear fuel assemblies. Table 2-4.

Figure 2-62 shows the Big Rock Point ISFSI. The storage system used at Big Rock Point is the FuelSolutions Storage System which consists of the W74 canister, the W150 storage cask, and the W100 transfer cask (Docket No. 72-1026). The W74 canister holds 64 Big Rock Point boiling water reactor used nuclear fuel assemblies. The fuel assemblies from Big Rock Point were loaded into W74 canisters from December 2002 through March 2003 (Leduc 2012). The fuel rods in the fuel assemblies are zirconium alloy-clad. The TS125 transportation cask (Docket No. 71-9276) is certified to transport the W74 canister. No TS125 transportation casks have been fabricated. In addition, the TS125 transportation cask is not certified for the transport of GTCC low-level radioactive waste. 2.5.1
