3.3. Perspectives for year 2004 and up to 2006Perspectives for year 2004 and up to 2006

Main task of current year is to complete full dismantlingof reactor IBR-30. It allows to start the licensing of the IREN facility construction

Third task is to complete an assembling of main equipment of LUE-200 in bld. 43

Second task is to deliver the IREN fuel to JINR from “Mayak” plant

Fourth task is a choice of the multiplying target producer




But it is crucial for future of whole project an approval by But it is crucial for future of whole project an approval by JINR directorate of the corrected time-table with respective JINR directorate of the corrected time-table with respective firm annual financing. firm annual financing.

The last point depends essentially from finding of new sources for support of the IREN project

• As it could be seen from tables presented below even in caseof optimal financing a start-up of IREN source may be realized not earlier than by the end of 2006
