  • Publication number: 20240071640
    Abstract: Provided is a chemical decontamination method that shortens the decomposition time of a reduction decontamination agent. An oxidization decontamination, a decomposition of an oxidization decontamination agent, and reduction decontamination using an oxalic acid aqueous solution are performed on a target piping of a BWR plant. After that, the oxalic acid is decomposed (S7). That is, a part of the oxalic acid is decomposed by irradiating the oxalic acid aqueous solution with ultraviolet rays upstream of a decomposition device (S8), and Fe3+ in the aqueous solution is converted to Fe2+. Hydrogen peroxide is supplied to the decomposition device (S9). In the decomposition device, the oxalic acid is decomposed by a catalyst and hydrogen peroxide, Fe2+ and hydrogen peroxide react to produce Fe3+ and OH*, and the oxalic acid is decomposed by OH*. A corrosion potential of the aqueous solution flowing out from the decomposition device is measured (S11).

  • Publication number: 20230003813
    Abstract: Proposed is a phase shift introduction method, a structure, and a circuit device for eliminating or minimizing a risk associated with dissimilar materials, solving in principle a problem of mixing of a signal current and a control current that occurs due to DC connection of a phase shifter to a signal line, and stably and reliably providing a phase shift that is desired to be introduced without being adversely effected by noise generated by an ambient magnetic field, which is generated due to use of an external power supply. A structure according to the present invention includes a phase shifter 101 and a closed-loop circuit 103 that is directly used for computation or storage, and a quantum phase shift is generated in the closed-loop circuit 103 by using a fractional flux quantum captured by the phase shifter 101 that is DC-separated from the closed-loop circuit 103.

  • Patent number: 10785133
    Abstract: A method includes monitoring, by one or more processors, a communications connection to a client, and detecting a disconnection event. The disconnection occurs when activity over the communications connection drops below a threshold. Based on detecting the disconnection event, the one or more processor creates a cloned virtual environment by cloning an original virtual environment obtained by the client via the communications connection. The original virtual environment and the cloned virtual environment execute in parallel. The one or more processor obtains process information and based on the process information, applies at least one process to the cloned virtual environment and monitors the communications connection, to detect a reconnection event, where the reconnection event includes activity over the communications connection being above or equal to the threshold.
