Use of the linear accelerator for incinerating the fission products of /sup 137/Cs and /sup 90/Sr
Transmutation of fission products /sup 137/Cs and /sup 90/Sr using the neutron produced by high energy proton collision with heavy nuclei were investigated. Because of the small thermal neutron cross section for (n,..gamma..) reaction of /sup 137/Cs (0.1 barn), a high neutron flux of 10/sup 17/ n/cm/sup 2/ sec is required to transmute /sup 137/Cs at a rate ten times faster than the natural decay. This range of high flux is attainable in the spallation reaction of high energy proton beam interact with liquid Pb target. The neutronic calculation by using NMTC, HIST3D, EPR, TAPEMAKER and ANISN codes indicates that the spallation neutron can transmute 222 kg /sup 137/Cs and 155 kg /sup 90/Sr fission products per year (at a rate of 10 and 30 times faster than their natural decay rate) by running a 300 mA, 1.5 GeV proton beam. Thus, if we transmute these fission products, just after a burning cycle, this accelerator can transmute these fission products produced in five or six 1000 MWe power plants.
