Priority:1
Status: Extended

Development of the IBR-2 Facility with a Complex of Cryogenic
Neutron Moderators


Leaders:     A.V. Vinogradov
A.V. Belushkin
A.V. Dolgikh

Participating countries and international organizations:
Azerbaijan, Belarus, Mongolia, Poland, Romania, Russia, Spain.

Issues addressed and main goals of research:
The main task of the theme is to increase the efficiency of the use of the IBR-2 facility for realization of the program of experimental investigations, maintenance of operational reliability and safety of the reactor, creation of a complex of cryogenic neutron moderators.

Expected results in the current year:
  • Provision of the IBR-2 reactor operation for physics investigations.

  • Check assembling, adjustment and testing of the backup movable reflector MR-3R at the FLNP test bench. Experimental investigations on determination of dynamic characteristics and parameters of vibrations of the units and structure modules at the stage of assembly and bench testing of MR-3R.

  • Operation of the test stand of the cryogenic moderator CM-201. Installation of the cryogenic moderator CM-201 in the regular place and putting it into trial operation. Development of requirements specification and project documentation for the cryogenic moderator CM-203 for beamlines 2 and 3.

  • Phased replacement and upgrade of the basic technological and electrical safety-related equipment of the IBR-2 facility.
