Description
Nuclear waste is one of the big issues of public acceptance of nuclear energy or nuclear uses in general. Nuclear waste is classified into high-level waste, transuranic waste and low-level waste. High level waste (HLW) can be transmuted into non-hazardous materials. Accelerator-driven system is used to transmute nuclear waste, moreover it can produce energy for generating electricity at the same time. ADS consists of two main parts: the accelerator and the subcritical reactor. In this study, the fuel density inside the subcritical reactor depends on the concentration of U-ThO$_{2}$(NO$_{3}$)$_{2}$, PuMA(NO$_{3}$)$_{4}$ dan HNO$_{3}$ (liquid phase). The reactor reaches subcritical conditions for RGPuMA, WGPuMA, SGPuMA when the concentration of PuMA-Nitrate is above 62.6 kmol/m3, 65.6 kmol/m3 and 66.6 kmol/m3 respectively. The investigation is to determine time taken of a subcritical reactor transmuting the long-lived nuclear waste to shorter-lived. Therefore, after the transmutation process the waste can be saved safely inside the nuclear waste repository.
