1. Introduction The role of accelerator driven systems (ADS) in promising atomic power engineering can be very important. It is mainly explained by the fact that they decrease the amount of long-lived radioactive waste. Specific properties of ADS permit to use different kinds of nuclear fuel such as uranium, plutonium, thorium, minor actinides (and their combinations), and then to use various nuclear fuel cycles. In ADS, long-lived fission products and actinides can be effectively transmuted. Characteristics of transmutation process depend on parameters of the transmutation installation. The main characteristics are neutron flux and spectrum and excess of neutrons, which can be used for transmutation. High thermal neutron fluxes make possible to obtain high transmutation rates and provide low loads of incinerated nuclides in the installation. ADS can provide also rather high excess neutrons for transmutation. Unfortunately, there is no possibility to increase significantly the neutron flux in fast neutron spectrum installations. However, fast neutron spectra could be preferable from the view point of neutron balance. The application of high-flux ADS for transmutation of long-lived fission products and actinides is studied in this paper. 2. Fission product transmutation Experts of different institutions came to an agreement about a list of long-lived fission products that should be transmuted rather than ultimately stored. The main nuclides are 99 Tc and 129 I. Their halflife is too long, and accumulation in spent nuclear fuel is rather high. Other radioactive fission products either could not be transmuted effectively or have a low importance. In Table 1, masses (in grams) of nuclides for transmutation of 99 Tc are presented for irradiation in constant neutron flux Φ = 10 14 neutr/(cm 2 s) and spectrum hardness γ = 0.4 typical for a light water blanket of an ADS (spectrum hardness is the share of epithermal neutrons in neutron flux). Data are normalised by 1 gram of initial 99 Tc. In Table 2, the same data are presented for Φ = 10 15 neutr/(cm 2 s) and spectrum hardness γ = 0.1 typical for heavy water blanket of ADS. In Tables 3 and 4, analogous data for transmutation of 129 I are given. They are normalised by 6.35 grams of initial 129 I and 1.40 gram of initial 127 I. Iodine isotopes are accumulated in spent fuel of light water power reactors in those amounts on account of power produced 1 MW-year. Table 1.

In transmutation of 99 Tc, isotopes of Ru, Rh and Pd are produced, while in transmutating 129 I, isotopes of Xe, Cs and Ba are produced. High flux provides much higher rate of transmutation. Ba 3. Actinide transmutation As for MA incineration, there are various viewpoints concerning the most preferable neutron spectrum. The choice of MA transmutation conditions is important to define a type of reactor or ADS installation. From this point of view, it is convenient to compare an efficiency of actinide transmutation in different facilities. In Table 5, calculated characteristics of transmutation modes in 3 types of transmutation facilities are presented: thermal power reactor PWR with neutron flux 5⋅10 13 neutr/(cm 2 s), fast neutron power reactor with neutron flux 5⋅10 15 neutr/(cm 2 s), and homogeneous heavy-water blanket of ADS with thermal neutron flux 5⋅10 15 neutr/(cm 2 s). These data were obtained by experts of ITEP and 889
