NUCLEAR MATERIALS MEASUREMENTS FOR ACCOUNTANCY AND CONTROL IN SSC VNIINM

The brief description of nuclear materials measurements System in Minatom of Russian Federation is presented. The interaction of these system elements with systems of measurements of nuclear materials at the facilities and in institutes of the Branch is shown. Measurements methods in SSC VNIINM for the purposes of their account are described including destructive and nondestructive methods and their application for the various physical forms of NM are given. The interaction between Analytical and Metroligical Divisions in SSC VNIINM is described. The used in SSC VNIINM methods of the analysis of nuclear materials, their accuracy data, the equipment for measurements, types of analyzed materials are shortly described and measurement accuracies are compared with the’ achieved level of measurements in the world (with target values).
