Abstract (en)

[origin: FR2565397A1] The conditioning device comprises an outer sealed envelope (1) inside which there is arranged a mixture formed of at least one emitter actinide element alpha with a medium and/or long period such as <237>Np, at least one emitter element alpha having a period shorter than 100 years such as <242>Cm or <244>Cm and at least one light element such as beryllium or boron capable of generating neutrons by reaction ( alpha , n). The presence of those different elements enables to obtain a destruction in situ of the long or medium period actinide elements by self-fission under the influence of the neutrons produced by reaction of the particles alpha with the light element.
