ABSTRACT

 

The sustainable management of high level nuclear wastes comprises the processes of geological disposal, partitioning and transmutation. Transmutation of high level nuclear waste is the process of changing long lived radio nuclides into short lived radio-nuclides through nuclear reactions by radioactive bombardment. With recent India-US nuclear deal, the utility of long lived radio-nuclides increases with target increase in nuclear power generation from 4,000 MW to 20,000 MW by 2020. Accelerator Driven System (ADS) technique is one of the hybrid techniques for nuclear power generation which can sustain its growth on the indian thorium-uranium fuel system and also useful for the incineration of the long lived nuclear wastes to make nuclear energy more acceptable to the society.

The present paper examined the physics of the ADS for nuclear energy and transmutation under the neutronic characterization, safety parameters, and dynamic behavior. The transmutation potential of ADS device compared with reactor based nuclear waste transmutation are also studied under different fuel systems. Under Indo-US nuclear deal, India is going to initiate an international collaboration programme on ADS to get rid of radiotoxic waste lodged in almost 2,00,000 metric tones of spent fuel that increases every year by 10,000 metric tones. Indian ADS programme is reviewed thoroughly for nuclear power production and incineration of radiotoxic waste. Generation
