Priority:

Status:

In-progress

Construction of the IREN Facility
(Project IREN)

Leader:

W. Furman
I. 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

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

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 2002:

The realization of the project IREN continues. The multiplicity target: completion of the technical project of the IREN facility, approval by Russian authorities; working out of the manufacturing technology of the multiplying target and respective technical documentation; assemble of the target cooling system. Decommisioning of the IBR-30 reactor: construction of bldg. 117/6 for storage of activated elements of IBR-30; manufacturing of the equipment for dismantling IBR-30; start-up of actual dismantling of IBR-30 and evacuation of its fuel load to a special storage. The linac LUE-200: completion of the electron gun manufacturing, its rig test; acompletion of the construction of the magnetic focusing system elements, including electric power sources; further tests of the RF system at rated power on a full scale RF rig; assembly and mounting of the second modulator in bldg.43; assembling and start of mounting of the cooling and thermostabilization systems and the vacuum system; system of diagnostics, control and safety - completion of the technical design, and assembling of the necessary equipment and beginning of the creation of the IREN control room.
Development of new experimental methods for beam measurements at IREN.
