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.

We use first principle electronic structure calculations to construct realistic models for magnetism in the context of dilute magnetic semiconductors. The predictions of the model are verified by recent experiments (see Nature 442, 436 (2006)).
