Abstract
The large consumption of resources necessitates the world to create efficient energy generation systems. Implemented with specific back-end strategies, renewable nuclear energy has been proven to be economically, environmentally and socially sustainable. There are currently three available options: open cycle, close cycle, and advanced cycle. The most significant cost of nuclear reprocessing is DGR, which is decreasing for the closed cycle and increasing for open cycle. Therefore, many other factors, such as waste management, the intangible asset, and the energy regulations of each country, should be taken into account when choosing the best strategy using the LCOE method. Many other countries have adopted a strategy meeting their national needs. Spain, however, is yet to make a decision. Based on the research carried out in this paper, it s suggested that costs are not a relevant criterion in order to select an energy policy for spent nuclear fuel management.
