  • Publication number: 20200395138
    Abstract: A covariance data creation apparatus configured to execute assembly calculations on a fuel assembly based on microscopic cross sections, the apparatus executing: a perturbation data generation step of deriving a plurality of perturbation quantities of the microscopic cross sections based on microscopic covariance data that is data regarding uncertainties of the microscopic cross sections, and generating microscopic perturbation data from the derived perturbation quantities of the microscopic cross sections; a macroscopic cross section derivation step of executing the assembly calculations based on the microscopic perturbation data generated at the perturbation data generation step, and deriving a plurality of macroscopic cross sections individually corresponding to the perturbation quantities of the microscopic cross sections; and a macroscopic covariance data generation step of generating macroscopic covariance data that is data regarding uncertainties of the macroscopic cross sections based on the macroscop

  • Patent number: 4164675
    Abstract: A rotor is manufactured by disposing a commutator integral with a rotary shaft centrally within a casting jig, arranging a rotor coil around the commutator, and integrally molding the assembly in synthetic resin. The rotor coil comprises a coil wound on a bobbin formed with positioning openings. Guide pins are provided within the jig in the region of the rotor coil for fitting engagement with the positioning openings in the latter. When molding the rotor, the rotor coil is properly positioned as a result of the engagement between the guide pins and the mating openings, assuring the molding of a balanced rotor.
