ABSTRACT:
An improved method and apparatus for transferring nuclear fuel elements between a fluid-filled storage pool and a cask is disclosed. The cask is supported within and is restrained by a tank which is transported between terminal locations of a nuclear facility. Transfer of fuel elements between a storage pool and the cask is accomplished by coupling the tank to a port of the pool. The transporter accurately positions and restrains the tank during transfer. In a preferred embodiment, the cask tank is unweighted from the transporter during transfer and is advanced into a fluid-sealed engagement with a port surface of the pool. In an alternative arrangement, the cask tank remains supported on the transport during its transfer and lifting means mutually engaging the transporter and tank advance the tank toward the port surface for establishing a coupling between the port and the cask. The method and apparatus substantially reduce fluid contact with an exterior surface of the cask during transfer and potential nuclear contamination; they enhance the protection of the transfer apparatus against seismic disturbances; and, they accomodate casks of different sizes.
