In addition: • RF modulator was assembled; • RF, vacuum systems were tested; • the accelerator grid was precisely mounted ; • the pulsed electron source was tested and mounted on the grid; Electron gun testing The metallic plutonium fuel for multiplying target was manufactured at “Mayak” and delivered to JINR in Dec. 2004 G.Shirkov, Basic Facilities, 02.06.2005 The budget of the IREN project 1994 - 3.7M$ 2005 ≥ 4.5 M$ due to: • inflation of US dollar • increasing of material cost • increasing of manpower cost It had been invested now ~ 2.25 M$ including ~ 950k$ in 2000-2004 The rate of project financing ~ 300 k$/year The estimated time for startup the facility: 2012 MoU between Kurchatov Institute and JINR was signed in February, 2005. KI is ready: • contribute to the IREN project (~100k$/year); • to apply jointly with JINR to the Russian Government for a special grant (~1M$) Section grids of LUE-200 Cooperation with KI is the most promising way for completion of IREN in 2008
