“…The methodology used in this article to calculate the costs of the back-end strategies of the nuclear fuel cycle is the Mariño model, which is fully described in Rodriguez-Penalonga. 27 This model was designed for the particular Spanish SNF management context. Due to the particularities of a specific country and a real scenario as opposed to a hypothetical situation, more flexibility is required.…”

“…Finally, the model can be used for both probabilistic approaches: deterministic or stochastic. In Rodriguez-Penalonga, 27 the results were obtained as a deterministic analysis, with a subsequent sensitivity analysis. Thus, this article presents a stochastic analysis for the scenarios T A B L E 2 Spanish nuclear installations 28,30,37 presented above.…”

“…The progressive shutdown at 50 years of operational lifetime has been further analysed in Rodriguez-Penalonga. 27 For the calculation of the costs, the year of reference is 2017. Thus, the construction and start of operation dates are the ones that were planned then.…”

“…Additionally, Table 3 shows a series of restrictions used by the model in order to calculate the material flows and Table 4 shows the parametrization of the costs, which was obtained through a series of analyses of the assumptions of different international studies and reports regarding the economic analysis of the nuclear fuel cycle, such as the MIT study by de Roo and Parsons, 9,10 the OCDE, 2 the reprocessing cost in the US, 35 the study of Ko and Gao, 12 Harvard 6 and BCG, 7 amongst others, such as real data from Finland, 39 Sweden 40 and Spain 36, 38,41 These analyses are further explained in Rodriguez-Penalonga. 27 Therefore, Table 4 presents a breakdown of the different unitary costs for each facility involved in the different scenarios. Firstly, the fixed (in M€) and the variable (M€/cask) part of the investment cost are presented for each facility.…”

This article presents two economic analyses performed with the Mariño model, which was specially designed to analyse the costs of different spent nuclear fuel (SNF) management strategies in the real Spanish context. These analyses are: (a) a Monte Carlo study for those strategies and (b) the effects of a longer operational lifetime for the Spanish nuclear power plants (NPPs) on the costs of spent nuclear fuel (SNF) management. For the first analysis, a triangular distribution for the different unitary costs was assumed and the data and assumptions from numerous studies were used to obtain the values required for the distribution. The second analysis was performed for the current official shutdown dates for the NPPs, and the results were compared to other operational lifetime scenarios. The main assumption for these scenarios was a progressive shutdown of the reactors, in order to avoid numerous shutdowns in a few years. These scenarios were proposed for 40 to 60 years of mean operational lifetime of the reactors. The results show that, for all scenarios analysed, the additional electricity production due to longer operational lifetimes compensate the extra costs caused by the larger amount of SNF to be managed. Additionally, for the current SNF management strategy, a progressive shutdown at 40 years of mean operational lifetime has shown to entail lower costs than the official shutdown scenario. However, a strategy without a centralised interim storage facility would be the most economically favourable one for all the scenarios analysed.

“…The basis for the data research on Nuclear Power Reactors is the Power Reactor Information System (PRIS) database from the International Atomic Energy Agency (IAEA) [6]. Other authors have taken data from this database for their research in nuclear science [7,8]. To study the obtained data, a parameter called operating factor (OF) has been used in this paper, which is defined as the relative frequency of PWR reactors operating around the world (in percentage):…”

Nuclear energy is presented as a real option in the face of the current problem of climate change and the need to reduce CO2 emissions. The nuclear reactor design with the greatest global impact throughout history and which has the most ambitious development plans is the Pressurized Water Reactor (PWR). Thus, a global review of such a reactor design is presented in this paper, utilizing the analysis of (i) technical aspects of the different variants of the PWR design implemented over the past eight years, (ii) the level of implementation of PWR nuclear power plants in the world, and (iii) a life extension scenario and future trends in PWR design based on current research and development (R&D) activity. To develop the second analysis, a statistical study of the implementation of the different PWR variants has been carried out. Such a statistical analysis is based on the operating factor, which represents the relative frequency of reactors operating around the world. The results reflect the hegemony of the western variants in the 300 reactors currently operating, highlighting the North American and French versions. Furthermore, a simulation of a possible scenario of increasing the useful life of operational PWRs up to 60 years has been proposed, seeing that in 2050 the generation capacity of nuclear PWRs power plants will decrease by 50%, and the number of operating reactors by 70%.

The reviewed papers presented here provide a general overview of worldwide radioactive waste-related studies conducted in 2019. The current review includes studies related to safety assessments, decommission and decontamination of nuclear facilities, fusion facilities, and transportation. Further, the review highlights radioactive wastewater decontamination, management solutions for the final disposal of low-and highlevel radioactive wastes (LLRW and HLRW), interim storage and final disposal options for spent fuel (SF), and tritiated wastes, with a focus on environmental impacts due to the mobility of radionuclides in the ecosystem, water and soil along with other research progress made in the management of radioactive waste. © 2020 Water Environment Federation • Practitioner points • The release of radionuclides and their subsequent fate and transport in the environment poses public health concern and has stimulated recent research on the waste management techniques. • Seeking a safe and environmental-friendly solution is the current trend for existing and projected inventories of radioactive waste. • Significant progress in the field of geological disposal of radioactive waste has been made in the last two decades.
