燃料棒の押付け拘束力測定装置。 In a nuclear fuel rod pressing restraint force measurement device that measures the pressing restraint force of an elastic protrusion provided on a nuclear fuel support grid of a nuclear fuel assembly, a guide shaft and a guiding shaft each having a stopper at one end are provided on a fixed plate. A movable plate is fitted into a pair of holes so as to be movable in the axial direction, and a movable plate is fixed to the guide shaft and the other end of the guide shaft, and a displacement measuring element and a movable plate are placed between the movable plate and the fixed plate. A compression spring is inserted to bias the plate in the direction opposite to the fixed plate.
A nuclear fuel rod pressing restraint force measuring device characterized in that a steel wire passing between the elastic protrusion and the nuclear fuel rod is stretched between a pair of wire holding arms projecting from one end of the movable plate.
