Abstract: A container accommodation condition determination method of determining an accommodation condition for accommodating a plurality of waste pieces, obtained by at least cutting radioactive waste, into at least one storage container, for obtaining at least one waste body by accommodating the plurality of waste pieces into the at least one storage container, includes: a step of, assuming, for each of a plurality of arrangement condition candidates specifying the storage container in which each of the waste pieces is to be stored and an accommodation position inside the storage container, that the waste pieces are arranged inside the storage container in accordance with the arrangement condition candidate, selecting at least one of the arrangement condition candidates which satisfy a limiting condition required for the waste body in each of the storage containers; a step of calculating a necessary storage container number which is the number of the storage container required to accommodate the plurality of waste p

Abstract: A method for decommission of a nuclear power plant includes: a step of removing fuel from a reactor vessel and storing the fuel in a fuel storage pool; a step of carrying the fuel out from the fuel storage pool; a step of, after removing the fuel from the reactor vessel, taking a reactor internal structure inside the reactor vessel out to a work pool storing water and being positioned above the reactor vessel, and decommissioning the reactor internal structure under the water stored in the work pool; a step of carrying the decommissioned reactor internal structure out from the work pool; and a step of, after carrying the reactor internal structure out from the work pool, draining the water from the work pool. The step of taking out and decommissioning the reactor internal structure is started before completion of carrying out of the fuel from the fuel storage pool.

Abstract: A focusing device that includes a differential interference prism used in differential interference observation in a focusing detection optical system includes: a light source that emits light with which a measurement surface of an observation sample is irradiated; a photo detection unit that detects light from the measurement surface; a focusing detection unit that detects an error signal near a focusing point of the measurement surface on the basis of an output signal from the photo detection unit; and a condition changing unit that changes an acquisition condition of the error signal.

Abstract: A microscope system includes a plurality of actuators configured to cause components of a microscope to operate, a plurality of power drivers configured to drive the plurality of actuators, respectively, an actuator controller configured to control the plurality of actuators through the plurality of power drivers, and a control management unit configured to control the actuator controller to designate any one of the plurality of power drivers to output a start signal for allowing the designated power driver to start operation to the designated power driver, and to control the actuator controller to stop outputting of the start signal to the designated power driver and the other power drivers other than the designated power driver until passage of a settling time in which driving of one of the plurality of actuators in response to the operation of the designated power driver is completed and then enabled again.

Abstract: The microscope system comprises: an imaging apparatus used for picking up an image of a specimen; an electric unit; a control apparatus for controlling turning On and Off of the power supply to the electric unit; a storage apparatus storing the initialization requirement time of the electric unit; and a drive management arithmetic operation apparatus for calculating, on the basis of an image pickup interval and initialization requirement time, a clock time for controlling turning On/Off of the power supply to the electric unit.
