Nuclear fuel costs are a minor proportion of the total generating costs of nuclear power plants. However, the capital costs of building and financing nuclear power plants make up a large percentage of the cost of nuclear electricity. Fuel costs for nuclear power have been steadily decreasing, with fuel costs in the USA declining by 23% between 2012 and 2019. Uranium, the primary fuel for nuclear power, is a highly concentrated source of energy that is easily and cheaply transportable. Uranium prices vary, with the cost of disposal of depleted uranium as U3O8 in cemented form in a mine estimated at $4.57 per kg UF6. The fabrication of fuel from natural uranium can range between $200 and $400 per kg U. The cost of nuclear power is influenced by various factors, including construction, safety regulations, and waste management, which can impact the economics of nuclear energy.

Nuclear fuel fabrication costs
The fabrication of nuclear fuel involves several steps, including the mining and milling of uranium ore, conversion and enrichment processes, and the final fuel assembly. Each of these steps incurs costs that contribute to the overall fabrication expense.
The cost of fabricating fuel from natural uranium, designed for burnups of 43 GWd/t U, ranges between 200 and 400 dollars per kg U. This cost takes into account the uranium price, conversion costs, and production losses during the fabrication process.
Additionally, the fabrication process generates waste that requires proper management and disposal. The disposal cost of depleted uranium as U3O8 in cemented form in a mine is estimated at $4.57 per kg UF6. However, meeting the requirements for long-term containment of uranium and its decay products can increase the estimated costs to $160 per kg U or $110 per kg UF6. These waste management costs are crucial considerations in the overall fabrication expense.
It is worth noting that fuel costs represent a minor proportion of the total generating costs for nuclear plants. Capital costs, such as building and financing, typically make up a larger percentage of the overall expense. However, fuel costs have been steadily declining, with a 23% decrease in the USA between 2012 and 2019, according to the Nuclear Energy Institute. This highlights the increasing efficiency and cost reduction in fuel fabrication processes.

Uranium price
Uranium is a silvery-white, radioactive chemical element that is essential for producing nuclear fuel. Uranium has the advantage of being a highly concentrated source of energy, easily and cheaply transportable. One pound of uranium can produce as much energy as three million pounds of coal through fission. The demand for nuclear power, as well as the global supply of uranium, often affects the price of the commodity. Its price is often inversely affected by changes in the demand for fossil fuels. Uranium prices can be volatile, driven by various factors such as supply and demand, geopolitics, and weather conditions.
The cost of nuclear power construction has varied significantly across the world and over time. Fuel costs for nuclear plants are a minor proportion of total generating costs, though capital costs are greater than those for coal-fired plants and much greater than those for gas-fired plants. Nuclear power plant construction is typical of large infrastructure projects around the world, and their costs and delivery challenges tend to be underestimated.
Capital costs, which include building and financing nuclear power plants, represent a large percentage of the cost of nuclear electricity. In 2014, the US Energy Information Administration estimated that for new nuclear plants going online in 2019, capital costs would make up 74% of the levelized cost of electricity, higher than the capital percentages for fossil fuel power plants. Fuel costs are one area of steadily increasing efficiency and cost reduction. For instance, in the USA, fuel costs declined by 23% between 2012 and 2019.
Nuclear energy averages 0.4 euro ¢/kWh, much the same as hydro; coal is over 4.0 ¢/kWh (4.1-7.3), gas ranges from 1.3-2.3 ¢/kWh, and only wind is better than nuclear at 0.1-0.2 ¢/kWh average. These are the external costs only, and do not include the external costs of global warming. A further study calculated external costs for nuclear power to be €18-22/MWh, including about €5/MWh for health impacts, €4/MWh for accidents, and €12/MWh for 'resource depletion', which relates to the consumption of finite fuel resources in the present rather than in the future.

Nuclear power construction costs
The cost of constructing a nuclear power plant is typically higher than that of coal- or gas-fired plants due to the need for specialised materials, advanced safety features, and backup control equipment. These safety features have become even more critical after incidents like Fukushima, which have influenced the design, layout, and cost of future nuclear plants.
Capital costs, which include site preparation, construction, manufacturing, commissioning, and financing, make up a large portion of nuclear power construction costs. Financing costs, in particular, can add around 30% to the overall cost, depending on construction time and interest rates. The longer the construction period, the higher the financing costs will be.
Historically, nuclear power construction costs have seen steady and dramatic increases. For example, in the 1970s and 1980s, labour costs for plant construction in the United States increased significantly, with final construction costs often exceeding initial estimates by two to four times. Similar trends have been observed in more recent projects, with reactors under construction in Georgia projected to cost twice their original estimates.
However, it is worth noting that in countries with continuous development programs, like South Korea, capital costs have been contained or even reduced. Additionally, global median construction periods have decreased over the last 15 years, which can help mitigate financing costs.

Capital costs
Nuclear power construction costs have varied significantly worldwide and over time. Capital costs, which refer to the building and financing of nuclear power plants, represent a large percentage of the cost of nuclear electricity. Fuel costs for nuclear plants are a minor proportion of the total generating costs, and operational and maintenance costs are also relatively small components of the total cost.
In 2014, the US Energy Information Administration estimated that for new nuclear plants coming online in 2019, capital costs would make up 74% of the levelized cost of electricity. This is higher than the capital percentages for fossil-fuel power plants (63% for coal-fired plants, 22% for natural gas), and lower than some other non-fossil fuel sources (80% for wind, 88% for solar PV). The French nuclear plant operator Areva claims that 70% of the cost of a kWh of nuclear electricity is accounted for by the fixed costs from the construction process.
The time taken to complete a nuclear power plant can significantly impact the capital costs. In the United States, contemporary nuclear plants commonly take over a decade to build, whereas Japanese nuclear power plants take an average of three to four years, and French power plants between five and eight years. The lengthy construction process in the US is partly due to the Nuclear Regulatory Commission's (NRC) multi-step licensing process, which requires approval from multiple regulatory agencies. This has inflated the cost of nuclear power by two orders of magnitude.
The industry consensus is that a 5% discount rate is appropriate for plants operating in a regulated utility environment, while a 10% discount rate is suitable for a competitive deregulated or merchant plant environment. An independent MIT study from 2003 used a more sophisticated finance model and found a higher average discount rate of 11.5%.
The proven dangers of nuclear power amplify the economic risks of expanding reliance on it. The stronger regulation and improved safety features called for after the Fukushima disaster will likely require costly provisions that may price nuclear power out of the market. The worst-case nuclear accident costs are so large that it would be challenging for the private insurance industry to carry the risk, and the premium cost of full insurance would make nuclear energy uneconomic.

Cost of nuclear power vs. alternatives
Nuclear power is a relatively inexpensive, low-carbon way to produce electricity. However, the true costs of nuclear power are difficult to calculate, and there is debate about whether it is a cost-effective energy source.
Nuclear fuel costs are a minor proportion of total generating costs. Uranium, for example, is highly concentrated, and a little goes a long way. However, capital costs are greater than those for coal or gas-fired plants. The building and financing of nuclear power plants represent a large percentage of the cost of nuclear electricity. Nuclear power construction costs have varied significantly across the world and over time. There have been periods of stability and decline, but there have also been large and rapid increases in costs, especially in the 1970s in the United States.
The cost of nuclear power is also impacted by the long-term effects of nuclear waste disposal, which are challenging to assess. Researchers Robert Barron and Mary Hill have created a model that provides a more accurate way of factoring in the costs borne by future generations. They consider two alternative discounting schemes that account for the costs of nuclear power on future generations. They calculated that the cost of nuclear power as a strategy for low-carbon energy production in the future may be higher than previously thought.
When compared to other generation technologies, nuclear power has a higher levelized cost of electricity (LCOE). An October 2020 report from Lazard compared the LCOE for various generation technologies. For nuclear power, the capital cost, including financing, ranged from $7675 to $12,500 per kilowatt, and the LCOE was $129 to $198/MWh. For coal, the capital cost ranged from $3000 to $8400/kW, with an LCOE of $60 to $143/MWh. For gas combined cycle, capital costs were $700 to $1300/kW, and the LCOE was $65 to $159/MWh. However, it is important to note that these figures do not take system costs into account.
Nuclear power is cost-competitive with other forms of electricity generation, except where there is direct access to low-cost fossil fuels. The 2020 edition of the OECD study on Projected Costs of Generating Electricity showed that at a 3% discount rate, nuclear power was substantially cheaper than alternatives like coal and CCGT. At a 7% discount rate, it was comparable to coal, and at a 10% discount rate, it was comparable to both coal and CCGT.
In conclusion, while nuclear power has relatively low fuel costs and can be a cost-competitive energy source, it also comes with high capital costs and uncertainties about the long-term environmental and financial impacts of nuclear waste disposal. When compared to other generation technologies, nuclear power has a higher levelized cost of electricity (LCOE), but this can vary depending on discount rates and other factors.
