Abstract

Optimization of the fuel burn up is an important issue in nuclear reactor FUEL MANAGEMENT and technology. Radial enrichment distribution in the reactor core is a conventional method and AXIAL ENRICHMENT is constant along the fuel rod. In this article, the effects of AXIAL ENRICHMENT distribution variation on neutronic parameters of PWR core are studied. The axial length of the core is divided into ten sections, considering AXIAL ENRICHMENT variation and leaving the existing radial enrichment distribution intact. This study shows that the radial and axial POWER PEAKING FACTORs are decreased as compared with the typical conventional core. In addition, the first core lifetime lasts 30 days longer than normal PWR core. Moreover, at the same time boric acid density is 0.2 g/kg at the beginning of the cycle. The flux shape is also flat at the beginning of the cycle for the proposed configuration of the axially enrichment distribution.
