Abstract: An apparatus of tilting a seat cushion of a vehicle, includes a tilting motor, a pinion gear, a sector gear, and a tilting link which perform the tilting operation of the seat cushion and exert a binding force in a tilted state of the seat cushion and are provided to be connected to both of one side and the other side of a seat cushion frame, and has two sector gears positioned on left and right sides and connected to each other by a connection bar so that, by strengthening a binding force of the front portion of the seat cushion, it is possible to secure the safety of passengers in the event of a collision.

Abstract: A nuclear fuel simulation method is provided that includes: step (a) for receiving an input of data on the order in which nuclear fuels are moved; step (b) for extracting, from the data, information on nuclear fuels, the coordinates of locations from which nuclear fuels are unloaded, and the coordinates of locations into which nuclear fuels are loaded; and step (c) for simulating the information extracted in step (b) according to a flowchart of the data. The present invention has an advantage in that it is possible to accurately and quickly verify all fuel movement works requiring the unloading and loading of nuclear fuels by receiving an input of a huge amount of data on the order in which nuclear fuels are moved and systematically verify an error that may occur during a simulation according to a flowchart, which enables the workload of about three man-days, required per cycle for each reactor, to be done in three man-hours, thereby achieving a significant reduction in working time.

Abstract: A method for managing the movements of nuclear fuels is provided that includes: (a) loading a storage status map in which storage racks of an SFPR where spent fuels are stored and an NFS where new fuels are stored are mapped; (b) assigning the storage locations of nuclear fuels and the colors thereof in the storage status map; (c) receiving a pattern type input of tasks for designating the order in which nuclear fuels are moved and the locations to which the nuclear fuels are moved, and generating a movement flowchart; and (d) updating the storage status map according to the level at which the movement flowchart has progressed. The present invention has an advantage in that it is possible to quickly create a nuclear fuel movement flowchart by automating all fuel movement works requiring the unloading and loading of nuclear fuels, which enables the workload of about 30 man-days, required per cycle for each reactor, to be done in three man-hours, thereby achieving a significant reduction in working time.
