Original Abstract

For WWER reactor, especially for Dukovany NPP, the optimizing code ATHENA has been developed in collaboration of SKODA Nuclear Engineering and the University of West Bohemia for several years. The ATHENA code serves for reducing number of fresh fuel assemblies, which are necessary to insert into the core for each cycle, and for optimizing the positions of fuel assemblies. The operation of the ATHENA code for practical use in Dukovany NPP is at the beginning, but already now some studies by this code are performed. Ten cycles with new fuel study is one of them. The new fuel has an average enrichment of 4.38% of U235 and is without central hole. Together with inserting new type of fuel the reactor thermal power was increased from 1444 MWt to 1471 MWt. The results show good improvement of the length of the cycle including increasing of thermal power. Besides the fuel with an average enrichment of 4.38%, other similar fuel with average enrichment of 4.76% is considered. This highly enriched fuel is still only experimental. Several cycles of this fuel also show better performance, especially the length of the cycle. The results of the studies are summarized and will be shown below.
