Status of the project in current year During months after the 19 th PAC NP session main efforts were done on preparation for IBR-30 dismantling, installation of new linac and organization of transportation of IREN fuel elements from MAYAK plant and its storing at JINR. It was delivered a shadow shielding for new storage bld. 117/6It was delivered a shadow shielding for new storage bld. 117/6 The set of documents necessary for licensing of the storage in The set of documents necessary for licensing of the storage in Russian Agency for Radiation Safety is practically completed Russian Agency for Radiation Safety is practically completed But up to now it has not paid the dosimetric equipment necessary for But up to now it has not paid the dosimetric equipment necessary for commissioning of bld. 117/6. It can cause a derangement of full commissioning of bld. 117/6. It can cause a derangement of full IBR-30dismantling by the end of current year IBR-30dismantling by the end of current year

Status&perspectives-proposal on the extension But it is crucial for future of whole project an approval by JINR directorate of the corrected time-table with respective firm annual financing. But it is crucial for future of whole project an approval by JINR directorate of the corrected time-table with respective 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 case of optimal financing a start-up of IREN source may be realized not earlier than by the end of 2006
