NONDESTRUCTIVE MEASUREMENT METHOD AND APPARATUS OF THE WEIGHT OF URANIUM IN A COMPACT WITH TRISO-COATED FUEL PARTICLES USING STEREOSCOPIC 3D IMAGE

摘要

PURPOSE: A method and apparatus for nondestructively measuring uranium weight are provided to accurately measure the uranium weight of a nuclear fuel by generating an X-ray radiography image as a 3D image. CONSTITUTION: An X-ray radiography image is obtained by rotating fuel elements mixed with a fuel nucleus and a graphite matrix(S20). The X-ray radiography image is comprised of a 3D image. The number of fuel nucleuses or volume of a fuel nucleus region is measured(S40). Uranium weight of the fuel element is obtained(S50).
