Initial Site-Specific De-Inventory Report for Big Rock Point Report No.: RPT-3014537-002
skid to the trailer. If not already in place, the bolt-on lifting eyes are installed at the four corners of the intermodal skid. The intermodal skid is then disconnected from the heavy haul trailer. Using the intermodal skid horizontal lift fixture, the lifting cables are attached to the four bolt-on lift eyes of the intermodal skid and the loaded intermodal skid is lifted from the heavy-haul trailer to a location where it can be disassembled and the intermodal skid disconnected from the horizontal lift fixture lifting cables. Operations will remove the personnel barrier to allow access to the transportation cask’s exterior surface and the personnel barrier inspected for any damage that may have occurred during transport. Radiation and contamination surveys will continue to be performed. Operations will then remove the impact limiter attachment nuts and washers from each impact limiter and the impact limiter attachment studs. Once this activity is completed the first impact limiter will be lifted away from the transportation cask. Operations will then inspect these items (bolting hardware) for any damage that may have occurred during use. This second impact limiters will be removed following this same process. Radiological personnel will survey the transportation cask and impact limiters to assure acceptable contamination levels. The lower trunnions will now be installed onto the transportation cask to allow it to be secured to the docking collar and the storage cask. Using the intermodal skid horizontal lift fixture, operations will attach the lifting cables to the four bolt-on lift eyes of the intermodal skid. Once the rigging is attached, operations will lift the transportation cask and intermodal skid and position the skid onto the skid positioning system and secure the intermodal skid to the skid positioning system and remove the rigging from the cask. Using a portable crane and the horizontal lid handling fixture, operations will attach the fixture to the transportation cask lid and unbolt the transportation cask lid and remove it. Radiological personnel will survey the transportation cask lid and cask cavity for contamination. If required by the transportation cask SAR, the lid seal may be removed and the seal areas on the cask lid and body cleaned and inspected and a new seal installed. Using the portable crane, operations will install and engage the horizontal lid-handling fixture onto the storage cask lid. The storage cask lid bolts are de-tensioned and removed allowing for the lid to be removed. Contamination surveys will be conducted on the storage cask internal surfaces and decontamination will be performed as needed. Inspections will be performed on the storage cask lid and the exposed surfaces of the canister (W74). The storage cask lid will be subsequently rigged and then removed by operations. During this operation, continuous radiation surveys will be conducted to ensure radiation levels are acceptable for performing the canister transfer activities. If radiation levels are exceeded, then the operation will be stopped and the lid re-installed onto the storage cask, if needed. Once the levels are verified to be acceptable, operations will rig the storage cask docking collar and position it and install it on the storage cask. Operations will remove the skid positioning securement device and position the transportation cask horizontally using the skid positioning system so that the top end of the transportation cask is within a few inches of the top end of the storage cask. Using the skid positioning system, optical survey equipment, and the alignment marks on the transportation cask and the storage
