[en] Higher burnups and more demanding in-pile conditions require not only advanced product designs but also higher process capabilities in nuclear fuel manufacturing. This can only be achieved by implementation of advanced technologies and systematic application of statistical process control methods. Examples of process improvements established at different manufacturing areas within Advanced Nuclear Fuels GmbH are given. In the mid term perspective adequate processes and reliable products shall give a sound basis to substitute numerous order specific product examinations by efficient order independent process supervision to the largest possible extent.
