Recent improvements in the design and manufacture of LWR fuel

Strong competition among the nuclear fuel vendors on the LWR fuel market is the main driving force for improvements in the design and manufacture of the LWR fuel. Nuclear utilities are requesting more advanced fuel, which will increase the fuel availability and lower fuel cycle cost. The fuel vendors' answer to this request has been an introduction of several improvements in the design and manufacture of their fuel. In this article the current trends in advanced fuel designs and development of improved materials, which have improved the fuel utilization and availability, are discussed in more detail. Also, the impact of these improved features on the safety analyses has been evaluated.
