Abstract: A method and system detects failures in nuclear fuel assemblies (600). A water treatment device degasses/removes fission gases from water used in the canister (500) of a vacuum sipping device (30). A sipping procedure then detects a failure in a fuel assembly in the canister. The degassing improves a signal-to-noise ratio of the detector used during the sipping process, and improves the failure detection sensitivity of the system. Additionally and/or alternatively, gas may be recirculated through the canister water before the vacuum is applied so that fission gas concentration in the recirculating gas reaches a baseline equilibrium with the canister water. The vacuum is thereafter applied and the sipping procedure proceeds such that an increase in detected radioactivity over the baseline equilibrium indicates a leak in the fuel assembly.

Abstract: A file cloning process allows for quickly cloning files within a filesystem, such as when a user makes a copy of a directory containing files and subdirectories of files. A priority based main queue is filled by a depth first traversal of the directory to be copied with work items corresponding to files and subdirectories. Worker threads refer to the main queue for file cloning, subdirectory copying and directory traversal. Files that have not been modified since a most recent checkpoint are cloned without issuing a checkpoint request. Files that have been modified since the most recent checkpoint are moved to a delay queue. Once a checkpoint of the file system completes, the files in the delay queue are then moved to the main queue to retry cloning thereof. A secondary queue is also provided to prevent worker threads from becoming deadlocked in the main queue.

Abstract: The disclosure is to more appropriately perform high-quality printing in a case of using ultraviolet curing ink in a serial type inkjet printer. In a printing apparatus for performing printing in an inkjet mode, an inkjet head for Y color, an inkjet head for M color, temporarily hardening light sources, an inkjet head, and an inkjet head are arranged such that their positions in the sub scan direction are deviated from each other. With respect to each position on a medium, after the inkjet head ejects ink drops, the temporarily hardening light sources hardens the ultraviolet curing ink of the Y color on the medium, to a temporarily hardened state, before the inkjet head ejects ink drops, and then the inkjet head ejects ink drops of the M color onto the area where the ultraviolet curing ink of the Y color has hardened to the temporarily hardened state.
