Neutronics-processing Interface Analyses for the Accelerator Transmutation of Waste (atw) Aqueous–based Blanket System
نویسنده
چکیده
Neutronics-processing interface parameters have large impacts on the neutron economy and transmutation performance of an aqueousbased Accelerator Transmutation of Waste (ATW) system. A detailed assessment of the interdependence of these blanket neutronic and chemical processing parameters has been performed. Neutronic performance analyses requi’re that neutron transport calculations for the A’TW blanket systems be fully coupled with the blanket processing and include all neutron absorption in candidate waste nuclides as well as in fission and transmutation products. The effects of processing rates, flux levels, flux spectra, and external-to–blanket inventories o n blanket neutronic performance were determined. In addition, the inventories and isotopics in the various subsystems were also calculated for various actinide and long-lived fission product transmutation strategies .

Criticality concerns, decay heat management and radioactive waste handling are perceived as the primary, unsatisfactorily resolved technological problems of nuclear reactors. They all originate from very specific features of a fission phenomenon: self-sustained chain reaction in fissile materials, very strong radioactivity of fission products and very long half-life of some of the radioactive f...
