Abstract

The methods of the neutron-physical parameter measurements of the subcritical assembly neutron source driven with an electron linear accelerator during start-up are described in the article. The results of neutron multiplication factor and reactivity measurements by different methods are represented. The measurement results are compared with each other and with simulation results of MCNPX code. The measured results of the facility parameters are analyzed.
