In the planning and management of the interim storage of spent nuclear fuel, the technical and economic parameters that are involved have a significant role in increasing the efficiency of the storage system. Optimal parameters will reduce the total economic costs for countries embarking on nuclear energy, such as the UAE. This study evaluated the design performance and economic feasibility of various structures and schedules, to determine an optimal combination of parameters for the management of spent nuclear fuel. With the introduction of various storage technology arrangements and expected costs per unit for the storage system design, we evaluated eight major scenarios, each with a cost analysis based on technological and economic issues. We executed a number of calculations based on the use of these storage technologies, and considered their investment costs. These calculations, which were aligned with the net present value approach and conducted using MS Project and MATLAB software programs, considered the capacities of the spent fuel pools and the amount of spent nuclear fuel (SNF) that will be transferred to dry storage facilities. As soon as they sufficiently cool, the spent nuclear fuel is to be stored in a pool storage facility. The results show that applying a centralized dry storage (CDS) system strategy is not an economically feasible solution, compared with using a permanent disposal facility (PDF) (unless the variable investment cost is reduced or changed). The optimal strategy involves operating a spent fuel pool island (SFPI) storage after the first 20 years of the start of the permanent shutdown of the reactor. After 20 years, the spent fuel is then transferred to a PDF. This strategy also results in a 20.9% to 26.1% reduction in the total cost compared with those of the other strategies. The total cost of the proposed strategy is approximately 4,307 million USD. The duration of the fuel storage and the investment cost, particularly the variable investment cost, directly affect the choice of facility storage.

“…Second, depreciation cost changes according to the method of calculation as it is derived systematically instead of relying on actual expenses [9][10][11][12]. Third, it accounts for a higher proportion of cost with increasing purchasing costs of tangible assets, which are subject to depreciation [13][14][15].…”

The Korean Government has been implementing a nuclear phase-out policy since 2017. Nuclear power plants accounted for 30.0% of the total power generation in 2016; this figure fell to 25.9% at the end of 2019, and the average Capacity Factor (CF) of a nuclear power plant approximately dropped from 89.1% to 69.2%. The nuclear phase-out policy presents severe consequences for the sustainable management of the nuclear power industry. Accordingly, the purpose of this study is to analyze the effect of a decrease in the nuclear capacity factor under the nuclear phase-out policy on the depreciation cost per unit using the Straight-Line Method (SLM) and Decelerated Depreciation Method (DDM) and to provide recommendations from a sustainable management perspective. The results show that the decrease in CF of nuclear power plants has a negative impact on sustainable development of the nuclear power industry. DDM is more beneficial than the SLM during this initial stage of depreciation under the nuclear phase-out policy. In addition, in the early stages of projects or immediately after attracting large-scale investments, DDM can offer more positive signs for stockholders by calculating a smaller net loss or a higher net profit.

“…1 On the one hand, equilibrium models analyse a fixed image of the material flows, at a moment of stability of the nuclear fuel cycle, in a static status. They are easy to analyse and implement, which is why they have been thoroughly used internationally, such as by the OCDE, 2 Kim et al 3 among others shown in Table 1. On the other hand, dynamic models vary the material flows over time, as well as the costs associated to the nuclear fuel cycle.…”

A proper spent nuclear fuel management strategy could enhance the continuity of nuclear power in the Spanish energy mix

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.
