This paper shows basic features of different fuel assembly FA application for VVER-1000 in a closed fuel cycle based on REMIX-technology. This investigation shows how the change in the water fuel ratio in the VVER FA affects on the fuel characteristics produced by REMIX technology during multiple recycling. 1 Introduction In papers 2 4 it has been proposed to use in thermal reactors fuel made from unseparated mixtures of uranium There are several problems in the Russian nuclear energy and plutonium isotopes blended with enriched natural sector the huge quantity of accumulated spent nuclear fuel uranium. Such fuel is called as REMIX-fuel. Fuel SNF and the limited inventory of cheap natural uranium fabrication technology is called REMIX-technology. for fuel fabrication. The solution of these problems leads to During reprocessing minor actinides and fission products increase economic attractiveness of the nuclear industry. FPs are removed. The main achievements of the REMIX- The main decision is in the implementation of a closed fuel technology are simplified reprocessing process natural cycle and recycling of the SNF. There is program which is uranium savings multiple recycling and the possibility of based on the development of fast nuclear reactors in full core loading. In papers 5 6 some new variants of the Russian Federation. This technology will have a significant .
