2.5.2 Site Conditions Figure 2-65 provides an aerial view of the Big Rock Point site, where the reactor and associated structures have been removed. Electrical power is available at the Big Rock Point ISFSI; a transfer cask, gantry towers, horizontal transfer system, and J-skid 20 are present at the ISFSI. Herron (2010) stated that the equipment needed to transfer used nuclear fuel and GTCC low-level radioactive waste in W74 canisters from the W150 storage casks to the TS125 transportation cask is in place, is tested on a periodic basis, and preventative maintenance is performed. Figure 2-66 shows the transfer cask and J-skid, Figure 2-67 shows the gantry towers, and Figure 2-68 shows the horizontal transfer system at the Big Rock Point site. A rail spur that served the Big Rock Point site was removed in 1988 (NAC 1990). This spur was used for nine rail shipments of used nuclear fuel to West Valley, New York between 1970 and 1974 (NAC 1990). There is no on-site rail access at the Big Rock Point site (TriVis Incorporated 2005), and heavy haul truck transport would be necessary to reach nearby rail sidings or spurs. For example, a rail spur in Gaylord, Michigan was used for shipping the reactor pressure vessel
20 The J-skid is a built-up welded steel frame of heavy wide flange beams and cross members that is used to capture and engage the W150 storage cask for rotation by the gantry towers. This J-skid is also used to support the W150 storage cask in the horizontal orientation during W74 canister transfer.
