Priority:

Status:

In-progress

Construction of the IREN Facility
(Project IREN)

Leader:

W.I. Furman
I.N. Meshkov

Scientific Programme:
IREN Construction of the Intense Resonance Neutron pulsed source IREN based on a linear electron accelerator (LUE-200) and a neutron multiplying assembly.
Main characteristics of the IREN source: The LUE-200 has the electron energy 210 MeV, mean peak current 5 A, frequency 150 Hz, pulse width 0.25 µ s, and the mean power 10 kW. An electron pulse is converted into a burst of photoneutrons by a special target placed in the center of an air cooled breader.
The beryllium-tungsten target converter in a stainless steel envelope is cooled by He gas flow. The breeder is the subcritical plutonium core with the volume 2.5 l and the breeding coefficient 30.

The neutron parameters of the source are: fast neutron pulse width - 0.4 µ s, mean power - 12.5 kW, peak power - 220 MW, mean neutron flux 1.0

10 ¹⁵ n/s, peak flux - 2.7

10 ¹⁹ n/s, interpulse background - 5.6 % .

Expected main results in 2003:

The realization of the project IREN continues. The IREN multiplying target and decommissioning of the IBR-30 reactor. The multiplicity target: completion of the technical project and approval by Russian authorities. Placing of orders and start of manufacturing of shell and auxiliary systems. Completion and manufacturing of cooling system units. Decommisioning of the IBR-30 reactor: dismantling of the ractor and auxiliary systems, evacuation of its fuel load to a special storage. Repairs of the reactor hall and preparation for assembling of the IREN multiplying target. The linac LUE-200. Completion of manufacture and assembly of support constructions and linac service trestle in bldg.43. Electron source. Modernization of units, completion of complex rig tests, assembly in bldg.43. Magnatic focusing system. Completion of manufacture of system elements and electric power sources, magnetometric measurements, preparation for assembly. Pulse and HF-systems. Further tests at full power on a full-scale rig, assembly and mounting of the second modulator in bldg.43. Cooling and thermostabilization systems, vacuum system. Assembly to the extent necessary for the first stage of the LUE-200 project. System of diagnostics, control and safety. Completion of the technical design, assembling of the necessary equipment and the creation of the IREN control room.
Development of new experimental methods for beam measurements at IREN.
