NOZZLE OFFSET AMOUNT MEASURING APPARATUS FOR REACTOR

摘要

PURPOSE: A measuring apparatus for nozzle eccentricity degree of a nuclear reactor is provided to conveniently measure the eccentricity degree of an inner structure nozzle by comprising a measuring part in a fixing unit. CONSTITUTION: A measuring apparatus for nozzle eccentricity degree of a nuclear reactor comprises: a fixing unit (131), and a measuring part (141). The fixing unit is equipped in a lower head of the nuclear reactor, and combined to the nozzle. The measuring part is arranged along the axial direction of the fixing part to be relatively moved horizontally to the axis direction, and inserted to the nozzle of an inner structure.
