Feasibility Study for Minor Actinides Transmutation in Conventional Power Reactors

Characteristics of Minor Actinide Transmutation in Minor Actinide Burner Reactors and Power Reactor

One of the techniques of minor actinides transmutation is to recycle these nuclides into fission reactors. Two concepts of a minor actinides burner reactor with very hard neutron energy spectrum as well as very high neutronjlux me discussed. The fuel cycle facilities for these burner reactors am assessed to discuss the technical feasibili~ of these reactors. Transmutation of minor actinide in b...

Nitride Fuel and Pyrochemical Process Developments for Transmutation of Minor Actinides in Jaeri

The Japan Atomic Energy Research Institute (JAERI) has proposed the concept of the transmutation of minor actinides (MA: Np, Am and Cm) with accelerator-driven systems (ADS), where MA nitride is adopted as a fuel material of a sub-critical core, because nitride fuel has the advantage of accommodating various MAs with a wide range of composition besides superior thermal and neutronic properties....

UWFDM-1313 Engineering Issues Facing Transmutation of Actinides in Z-Pinch Fusion Power Plant

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...

Transmutation of Cesium-135 with Fast Reactors

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...
