METHOD OF DETERMINING AT LEAST ONE TECHNOLOGICAL UNCERTAINTY FACTOR IN RESPECT OF NUCLEAR FUEL ELEMENTS AND METHOD OF DESIGNING, METHOD OF PRODUCING AND METHOD OF CHECKING THE CORRESPONDING NUCLEAR FUEL ELEMENTS

摘要

The invention relates to a method of determining at least one technological uncertainty factor in respect of nuclear fuel elements (23) as a function of variations in the production parameters of the elements (23) in relation to nominal values. The inventive method comprises a step involving the use, for at least one production parameter, of a collective variation in said parameter in relation to the nominal value within a batch of produced elements (23). The invention can be used, for example, to design, produce and check pellets for light water reactors.
