Status of the project in current yearDuring months after the 19th PAC NP session main efforts were

done on preparation for IBR-30 dismantling, installation of new linac andorganization of transportation of IREN fuel elements from “MAYAK”plant and its storing at JINR.

IBR-30 dismantling• It was delivered a shadow shielding for new storage bld. 117/6• The set of documents necessary for licensing of the storage in Russian Agency for Radiation Safety is practically completed• 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 IBR-30dismantling by the end of current

Linac installation• Very recently, on 11-12 March it was achieved practically planned parameters of the pulsed linac

electron gun• By the end of April it was completed an assembling of linac grid with geodesic accuracy

IREN fuel transportation• Transportation of the IREN fuel load is possible now only in autumn

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

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

• A detailed consideration of the most optimistic time-table presented at NP PAC session shows that even in the case of optimal financing a start-up of IREN source may be realized not earlier than by the end of 2006
