Study Analysis of Multiplication Factor on ADS Transmutation System

Abstract New research technology for partition and transmutation (P-T) of minor actinide (MA) contained in high-level waste (HLW) has been carried out to design accelerator-based system or commonly known as Accelerator Driven Subcritical (ADS) device. The objective this is eliminate minimize radioactive that long half-life develop long-term safety assurance HLW management. Analysis done by using Origen2.1 mCnP6 codes. As matrix, Th-232 with optimum weight 75% used.. Comparing , analysis results MCNP shows the use PWR nuclear spent fuel ADS device can be reprocessing U-238 nuclide, which source formation plutonium nuclide actinides. From discussion, it concluded observation on transuranic nuclides ORIGEN2.1 Code conducted successfully LMFBR library. 15%-Th232 justified most based K-inf reached at EOC various types. Mass reduction occurs U-236, U-235, U-234, Th-232, Np-237, Pu-238, Am-241, Pu-242, Cm 244. Radionuclides experience mass changes during cooling time are Pu-240, Pa-233, Cm-244.
