The accelerator driven subcritical assembly facility is under development in the National Science Center Kharkov Institute of Physics and Technology. The important component of the facility is an electron linac with energy of particles of 100-200 MeV and average beam current of 1 mA. In this paper we focus on the S-band electron linac design. The accelerator scheme includes the injector based on evanescence waves, rf chopper, five accelerating structures and energy compression system. The results of calculation of accelerating structure performances and linac systems are considered in the paper

Today accelerator driven subcritical assembly is candidate for the next generation of energy-generating nuclear facility, which could provide safe energy production, burning of transuranium elements and transmutation of radionuclides. Use of the electron beam with particle energy up to 150-200 MeV secures several advantages. Electron linear accelerators are much cheaper compared to hadron accelerators. Homogeneous irradiation of the assembly with neutrons could be provided. NSC KIPT together with ANL develops the project of a neutron source based on the sub-critical assembly driven by electron linear accelerator. Energy of electrons is 100-200 MeV. The target and assembly design is optimized to maximize the neutron source intensity with subcriticality of 0.98. Accelerator on average beam power of 100 kW, with repetition rate up to 300 Hz and pulse duration of 3,2 ms is under development. Transportation line should provide beam transfer with minimal losses of electrons and should form homogeneous distribution of the particle density at the target. Maximal value of a neutron flux is Fm=2x1013 n/(cm2s), and power of energy release in the result of nuclei fission is Pm≈ 100 kW.
