Influence of the New Spanish Legislation concerning the Management of Nuclear Waste

Abstract

The aim of the present paper is to present and analyse the results obtained from a comparative economic feasibility study performed for the two main nuclear spent fuel management cycles: Once-Through Cycle and Twice-Through Cycle in a Spanish scenario, taking into account the new Spanish legislation with which new tax provisions for generation and storage of nuclear waste must be included in the cycle costs.

Economic Analysis of the Management of the Nuclear Spent Fuel in Spain

“…It is also necessary to take a look at the tendency of those three factors that were established as the most determinant in predicting future changes in the total cost of each of the alternatives. The cost of reprocessing the nuclear fuel as it is shown in Figure 2 has a decreasing tendency which is in favor of the closed cycle, as presented in the previous works [8,9], while cost estimates for the construction of a repository are increasing. The clearest case occurs in the United States with the Yucca Mountain project where the costs have increased each time they have been reviewed, due to factors such as strong and more expensive security measures and more requirements in the design.…”

Novas tecnologias aplicadas em estudos de viabilidade econômica e financeira: uma revisão integrativa da literatura

“…Em relação aos procedimentos de EVEF, foi constatado que, de maneira geral, os trabalhos seguem a linha do que é apresentado no referencial teórico deste estudo, ou seja, focam principalmente em três indicadores de viabilida-de: TIR, VPL e payback. Entretanto, alguns estudos utilizam técnicas mais complexas de análise de viabilidade, como a metodologia multi-índice e a metodologia multi-índice avançada (Cao et al, 2016;Fletcher et al, 2017;Hailu Kebede & Bekele Beyene, 2018;Lavander et al, 2013;Moratilla Soria, & Villar Lejarreta, 2013) que, além de verificar a viabilidade econômica e financeira, servem para verificar o risco do investimento e a análise de sensibilidade, indicando o nível de estabilidade das variáveis do produto, ou seja, a resposta da viabilidade do produto se determinado insumo não puder ser comprado como planejado, por exemplo, quanto mais estável menor o risco.…”

Spent Nuclear Fuel Management: Levelized Cost of Electricity Generation and Analysis of Various Production Scenarios

“…For example, P. Högselius [8] explains that military ambitions and non-proliferation, technological culture, political culture and civil society, geological conditions and energy policy are the five main broad explanatory factors that are needed in order to analyze the differences in spent nuclear fuel policies between each country. Moreover, another important factor to consider is the tax policy of each country, as it has been explained for the Spanish scenario in different articles [6,9]. Analyzing the energy strategies of different countries, there are some of them, such as Sweden and Finland, that have assumed an open cycle strategy, having to construct deep geological repositories, whereas there are others that have decided to adopt the closed cycle, having to reprocess, recycle and, afterwards, vitrify and compact non-usable residue materials to be stored in the DGR.…”
