Title: Peprocessing method for spent nuclear fuel
Inventor: KANI YUKO
IPC: G21C19/44
Filed: 1999-11-25
Abstract: PROBLEM TO BE SOLVED: To improve the processing speed, simplify the process and reduce the size of a reprocessing facility for reprocessing spent nuclear fuel. SOLUTION: As the reprocessing method by fluoride evaporation method for spent nuclear fuel, a fluorination device (a fluidized bed type reactor) 3 and a fluorination device (a flame type reactor) 4 are used. By a fluorination reaction in the fluorination device (fluidized bed type reactor) 3, uranium fluoride is obtained. By a fluorination reaction in the fluorination device (flame type reactor) 4, mixture of fluorides of uranium and plutonium is obtained. By using the flame reactor for fluorination reaction of spent fuel in this manner, since a continuous processing of spent nuclear fuel becomes possible, the processing amount of spent nuclear fuel can be increased. Since the fluoride of uranium and plutonium is recovered as a mixture, the refining process can be deleted.

IPC: H04B7/24
Filed: 1990-11-29
Abstract: PURPOSE:To allow a base station to collect a data of a terminal station efficiently without data collision by sending a specific signal in advance from the base station to the terminal station so as to take a reply timing. CONSTITUTION:A signal A aiming at collecting a data of a terminal station is sent prior to voice communication from a base station 1 to give a reply timing to terminal stations 2-4, which send the terminal station data to the base station 1 as a reply signal even during the communication with the base station 1 in the given reply timing. Thus, the base station 1 sends a signal aiming at collecting the terminal station data prior to the voice communication to the terminal stations 2-4 to give a reply timing to the terminal stations 2-4. Thus, the terminal stations 2-4 sends the terminal station data to the base station 1 in a given timing to allow the base station 1 to collect the terminal station data without data collision.

Title: Zero-phase current detecting device
Inventor: UEDA AKIHIKO
IPC: H02H3/16
Filed: 1990-11-28
Abstract: PURPOSE:To improve precision by adding light signals of individual phases with no photoelectric transfer of them. CONSTITUTION:Individual phase light signals from photo-magnetic field sensors 5a-5c are fed to a photo-adder 8 via optical fibers 7a-7c, synthetically added in the light signal state, photoelectrically transferred by a light receiving element 9, and transferred into signals with proper magnitudes by a signal processing circuit 10. The sensors 5a-5c have different temperature characteristics. Ratios between the currents of three-phase distribution lines 1a-1c and output signals of the sensors 5a-5c differ among three phases due to the change of the ambient temperature. The output signal from the circuit 10 has noises and is not made zero even when the zero-phase current is not flowing, and a protective relay is erroneously operated. A correction arithmetic circuit 11 removes the error component, and the zero-phase current caused by a grounding accident is surely detected. High-precision detection can be performed.
