An accelerator-driven system for the destruction of nuclear waste

Abstract

Progress in particle accelerator technology enables the use of the proton accelerator as an effective tool for energy production and nuclear waste destruction. The Energy Ampliéer (EA) proposed by Carlo Rubbia and his group ì a subcritical fast neutron system driven by a proton accelerator ì may prove particularly effective in destroying, through éssion, transuranic elements produced by current nuclear reactors. Combined with the Adiabatic Resonance Crossing (ARC) concept recently tested in the TARC experiment at CERN, the EA provides an efécient and cost-effective method for transforming long-lived éssion fragments. A number of other application areas (production of radioactive isotopes for medicine and industry; fundamental neutron research, etc.) may beneét from the extension of the ARC concept as well.

“…The transuranium (TRU) elements, consisting of Pu and minor actinides (MA), and long-life fission products (LLFPs) in the spent fuel have been considered in several publications (Broeders et al 2000;NEA 2005NEA , 2006. Various studies have been made on the TRU and LLFP transmutations in FRs (Wakabayashi and Higano 1998;Ohki and Takaki 2002), PWRs (Budi and Kitamoto 2001;Yang et al 2004), BWRs (Budi and Kitamoto 2002), accelerator driven systems (ADSs) (Revol 2001;Saito et al 2002), and some special nuclear systems (Park et al 2002;Takibayev Fig. 2.205 Comparison of cladding surface temperature in single channel analysis (Cao et al 2008a) When the TRU amount is reduced by transmutation, the LLFPs will likely dominate the long-term dose associated with radionuclide release from the geologic repository.…”

“…The transmutation of 99 Tc and 129 I by loading in the PWR (Budi and Kitamoto 2001), FR (Wakabayashi and Higano 1998) and ADS system (Revol 2001) were widely studied to obtain better performance. To evaluate transmutation capability, a calculation scheme coupling SRAC and SWAT (Suyama et al 2000) codes is utilized in which SRAC is used to obtain the power distribution and SWAT is used to obtain the density of isotopes.…”

“…Figure 2.210 gives the capture cross sections of 99 Tc (Revol 2001) and 129 I (Ingelbrecht et al 2002). Figure 2.210 gives the capture cross sections of 99 Tc (Revol 2001) and 129 I (Ingelbrecht et al 2002).…”

Continuous spectra of light charged particles from interaction of 30 MeV energy protons with cooper

“…In the middle of the last century, the idea of creating a nuclear power system was put forward, implemented to date as the Accelerator Driven System (ADS), consisting of a proton accelerator (deuterons), a neutron-producing target and a subcritical reactor (blanket) with a thermal neutron flux [1,2]. In addition to the energy production, the system allows the transmutation of long-lived radioactive waste from the nuclear industry [3].…”
