摘要

With the progress made in the domain of high intensity accelerators, it appears now possible to design spallation sources delivering a very intense neutron flux. Spallation neutron sources are of practical interest in many domains like solid state and material science. Put into operation were ISIS - RAL (10 n/cm s ) which competes with the fast pulsed reactor, IBR-2, Dubna (10 n/cm s), the continuous spallation source SNQ, PSI (10 " n/cm s), the project AUSTRON (3,6 x 1016 n/cm2s), and the European project ESS (5 x 1016 n/cm2s). In such systems, spallation reactions induced by a high intensity beam (10 to 250 Ma) of GeV protons on a heavy target produce an intense neutron flux. The neutrons, after being moderated, are used to drive a sub-critical blanket. The extra neutrons provided by the accelerator allow the maintenance of the chain reaction, while burning the long-lived nuclear waste.
