Abstract

The paper focuses on the methods of dynamic control of nuclear fuel microobjects, both designed and approbated. These methods are based on the reconstruction of spatial geometric properties of microobjects with the usage of the outlines of two-dimensional shadow projections. To describe the microobject dimensions, the overall dimensions and average diameter are taken into consideration. To describe the shape factor, the non-sphericity coefficient is defined as the ratio of the maximum to the minimum overall dimension of an object. The metrological characteristics of the designed control methods are considered.
