Transmutation of Cesium-135 with Fast Reactors

چکیده
The neutronic feasibility has been studied for Cs transmutation with commercial fast reactors. By irradiating Cs, the existence of stable isotope Cs deteriorates an effective net reduction of Cs owing to new creations of Cs by double neutron capture reactions, because Cs recovered by an element-wise separation process contains the associated isotopes Cs, Cs and Cs except Cs. The following three issues were examined to improve the transmutation efficiency: (1) selection of proper moderator material, (2) element-wise separation after the decay of Cs, (3) irradiation-cooling repeating method. Consequently, the transmutation efficiency was improved somewhat but not to attain break-even condition. It turns out that the Cs transmutation is difficult with commercial fast reactors.

The initiation of the Global Nuclear Energy Partnership includes nuclear-based transmutation devices to recycle the spent fuel. Fusion can offer an alternative to the use of fast reactors for the transmutation of actinides. At a modest fusion power of 20 MW, a Z-Pinch driven sub-critical blanket can burn actinides and produce power. Several engineering issues have been examined: the effect of t...
