Comparative analysis of the final volume of waste generated in nuclear plants after treatment through two methods of immobilization

Resumo

Waste generated in nuclear power plants, classified as Intermediate and Low Level Waste, can be stored for hundreds of years, taking up space in the initial and final deposits, increasing transport and deposition costs. It makes essential to reduce volume not only in generation of raw waste, but also in its treatment. In order to identify a method that produces the smallest volume of waste product, two immobilization methods were compared: cementation and bituminization. For each method, a simulation based on the waste generation from a PWR plant was performed
