Wastes Management Through Transmutation in an ADS Reactor

الملخص EN

The main challenge in nuclear fuel cycle closure is the reduction of the potential radiotoxicity, or of the time in which that possible hazard really exists.

Probably, the transmutation of minor actinides with fast fission processes is the most effective answer.

This work, performed in SCK⋅CEN (Belgium) and DIMNP Pisa University, is focused on preliminary evaluation of industrial scale ADS (400 MWth, 2.5 mA) burning capability.

An inert matrix fuel of minor actinides, 50% vol.

MgO and 50% vol.

(Pu,Np,Am,Cm)O1.88, core content, with 150 GWd/ton discharge burn up, is used.

The calculations were performed using ALEPH-1.1.2, MCNPX-2.5.0, and ORIGEN2.2.
