Abstract: One embodiment of the invention provides a method for integrating a plurality of computer applications. The method includes receiving from a requestor a request of a target application. The request includes data identifying a target application and a target application service requested by the requestor. An abstraction layer receives the request. The method further includes using a Profile Manager in communication with the abstraction layer to receive data identifying the target application, to select a sack (a portable container for the request, e.g., a serialized object) and to select which of a plurality of sack content providers (SCPs) to use to interface with an appropriate element given the target application. The plurality of SCPs are in communication with the abstraction layer. The plurality of SCPs interface with a plurality of elements including at least a first application and at least a first hub.

Abstract: The present invention provides a locking assembly for locking in place an upper support plate above a nuclear fuel bundle. The locking assembly includes several different components, including one rotatable member that is movable between a first position for locking the support plate in place and an unlocked position for releasing the support plate so that it can be removed from the guide tubes in the fuel bundle assembly. The rotatable member is resiliently maintained at its locked and released positions, and the entire locking assembly is an integral unit without any loose parts regardless of the position of the rotatable member.
