Abstract:
PROBLEM TO BE SOLVED: To provide a disposal plant, method and system for controlling confinement of radioactive cesium.SOLUTION: A method for controlling confinement of radioactive cesium in a disposal plant where the radioactive cesium is confined includes the steps of: monitoring each distortion of a plurality of objects that are included in the disposal plant and where the radioactive cesium is confined; and monitoring the radiation dose of the radioactive cesium in the disposal plant, and further may include the step of performing processing depending on the results of the monitoring of the distortions.
Abstract:
PROBLEM TO BE SOLVED: To obtain a construction method of a large hall building constructing a building with a large internal space (a large hall) in a short time by utilizing an advatage of a cubicle unit construction method. SOLUTION: The invention is a construction method of a large hall building 1 by connecting a plurality of box-type units 9A-9C constituted of parallel two pairs of beams arranged in a square frame-shape and four corners connectedly supported at four corners of mutual beams and includes a process in which a plurality of units 9A-9C are installed on a flat foundation 51 face so as to surround the internal space 27 of the building, and a process in which stepping beams 41 are installed so as to be supported by the mutual external columns in the connection section so that the beams are put over at least two joints pinching the internal space 27 in the connections of mutual units.
