“…As the issue of spent fuel management is one of the most important of the future nuclear energy development in the world, the study of transmutation possibilities also relevant. There are many international projects in this way, for example: MYRRHA [4], YALINA [5], SAD etc., and Ukraine is no exception. We have already built a subcritical system with an electron accelerator in Kharkiv [6], and in the nearly future, it is planned to be launched.…”

The investigations directed to plutonium and minor actinides transmutations for two-zone subcritical reactor is considered in present paper. The distributions of thermal and fast neutrons in the subcritical system were obtained. The distributions of fission and capture reaction rates for 237Np and 243Am were analyzed from viewpoint of minor actinides transmutation. The transmutation simulations for different distributions of pin targets were carried out within the scope of this paper. The obtained modeling results for different nuclear waste isotopes were analyzed and discussed.

“…Let us also note that ex per i men tal low-power subcritical as sem bly "YALINA-BOOSTER", driven by D-T neu tron gen er a tor, is al ready built in Joint Insti tute for En ergy and Nu clear Re search (Sosny, Minsk, Belarus) [9]. The yield of neu trons in both aforemen tioned cases is es sen tially lim ited by the current strength of the par ti cle beam in side the ac cel er ator, while in crease of the cur rent strength up to a value needed for ap pli ca tions is a rather com pli cated problem [10].…”

In this paper we simulated the behavior of a simple ADS model, based on MOX fuel embedded in solid lead, in terms of multiplication coefficient k ef f , thermal power and absolute neutron spectra. In the first part of the paper, we report on the results obtained when modifying the reflector surrounding the fission core, by replacing pure lead with a layered graphite/lead structure. We found that, by appropriately choosing position and thickness of the graphite and lead layers, it is possible to obtain a "hybrid" system where the neutron spectrum in the core still exhibits a fast character, while the spectrum in the graphite layer is considerably softer, becoming thermal in the most peripheral positions. In order to obtain such a modulation of the neutron spectra from the center of the system to the periphery, a careful choice of the materials has to be made in order to avoid large variations of the local power at the core boundary. However, the smoothness of the power distribution is obtained at the expense of lower values of k ef f and the total power of the system. In the second part of the paper, we explored the option of adopting light water as coolant, instead of the helium gas assumed in the initial design. We found that this produces an increase in k ef f and thermal power, without significantly perturbing the fast character of the system and without introducing spatial power excursions in any place within the core. The characteristics obtained may allow to design a system where fast, mixed and thermal spectra can be used to expand the use of the ADS as an irradiation facility.
