Nuclear energy, released through a process called fission, is the energy source that keeps the plants going. The United States, which uses 19.9% of nuclear-generated electricity, is home to the world’s largest fleet of commercial nuclear power plants.
A nuclear power plant operates on the principle of nuclear fission. The process starts when a nucleus of an unstable atom splits up into two lighter nuclei and electrons, releasing tremendous amount of energy in the form of heat and radiation. This energy is later converted into electricity to power homes and industries. In this topic we talked about How much does it cost to run a nuclear power plant for a year, main advantages of nuclear power.
How much does it cost to build a nuclear power plant
According to the Nuclear Energy Institute, building a nuclear power plant requires an investment of $5 billion to $6 billion per unit. If the power plant is being built in an existing nuclear facility, then the cost would be around $3 billion.
How much does it cost to run a nuclear power plant for a year
It costs around $30 million to operate and maintain a 1,000 MW reactor for one year. This includes all operational expenses such as salaries of workers, maintenance of equipment, etc.
The average time required to construct a 1000 MWe reactor is about four years from start of construction till completion (including regulatory approval).
The cost of nuclear power plants is a hot topic these days. The price of oil and natural gas are rising, and nuclear power has been touted as an alternative energy source.
What are the costs associated with building a nuclear power plant
Construction costs: The first step in building a nuclear power plant is constructing the containment building that will house the reactor core. This can vary in size depending on the type of reactor being built: pressurized water reactors usually require larger containment structures than boiling water reactors because they have more radioactive fuel rods that require cooling. Once you’ve got your containment structure, it’s time to build your reactor vessel. This is where most of the radioactive material resides, along with all of your safety systems (including emergency cooling pumps). The most expensive part of construction is putting together all the pieces necessary to create a functioning nuclear reactor — including piping, equipment racks and instrumentation systems — into one complete system that can be operated safely day in and day out.
Operating costs: Once your nuclear power plant is up and running, there are many ongoing operating expenses that come along with it — from paying salaries for engineers and maintenance workers to buying fuel rods for your reactor core (which have
The cost of building a nuclear power plant is about $10 billion to $15 billion per reactor. The cost of operating a plant is about $1.5 billion per year.
The average lifespan of a nuclear reactor is 60 years, although some have been in operation for 40 years or more and are slated for decommissioning soon.
Nuclear reactors produce electricity by heating water to create steam that drives turbines to generate electricity. This process is called nuclear fission, which occurs when atoms split apart into smaller atoms and release massive amounts of energy (which can be harvested as heat).
The main advantages of nuclear power include:
Low-cost fuel supply — Nuclear power plants use uranium fuel rods as their primary source of fuel. Uranium is plentiful and relatively inexpensive compared with other fossil fuels used to generate electricity such as coal and natural gas. Nuclear power plants produce no air pollution because they don’t burn fossil fuels or release greenhouse gases such as carbon dioxide (CO2) into the atmosphere like coal-fired power plants do.
High efficiency — Nuclear reactors are highly efficient at producing steam from water, which can produce up to 35 percent more energy than other types of fossil fuels like
Nuclear power plants are expensive to build and operate, and they produce large amounts of radioactive waste. For these reasons, nuclear plants are expanding in only a few countries. The cost of building a nuclear plant can range from $4 billion to $50 billion, depending on the size and type of reactor.
In the United States, where nuclear power is produced by private utilities, not by federal agencies or electric cooperatives, customers pay for construction with rate increases spread over 20 years.
Operating costs depend on the type of fuel used and how much electricity is generated. For example:
Natural gas combined cycle plants have lower operating costs than coal or nuclear power plants because they require less fuel and have lower maintenance costs because they have fewer moving parts than other types of generators. However, they emit more nitrogen oxides (NOx) than either coal-fired or nuclear plants because they use natural gas to produce electricity through combustion.
The cost of building a nuclear power plant is fairly high. In the United States, a new nuclear power plant costs around $5 billion to $6 billion per gigawatt (GW) of capacity. That’s about twice as expensive as building a coal or natural gas plant.
In 2017, the average cost of solar was around $3 per watt, according to the Solar Energy Industries Association (SEIA). And wind projects averaged around $2.5 million per megawatt of capacity in 2017, according to the American Wind Energy Association (AWEA).

The chart below shows how much it costs to build different types of energy plants:
The cost of nuclear power varies widely depending on the type of reactor and construction costs.
The average cost of a new nuclear plant in the United States is $5,000 per kilowatt (kW). For comparison purposes, the average cost of a natural gas combined cycle plant is $1,200 per kW and coal-fired plants are $1,500 per kW.
The cost of a new nuclear power plant can vary widely depending on its size and location. In early 2011, for example, Duke Energy announced that it would spend about $13 billion to build two new reactors at its existing Shearon Harris Plant in North Carolina. The twin 1,700 megawatt reactors would replace older units at the facility and would be built by Westinghouse Electric Co., which filed for bankruptcy protection in March 2011.
In contrast, Southern California Edison has proposed building a twin-reactor nuclear power plant at its San Onofre site near San Diego with an estimated price tag of $10 billion or more.
The costs of nuclear power are high, but the cost of not having a diverse portfolio of low-carbon energy sources is higher. The cost of nuclear power is estimated at between $97 and $135 per megawatt-hour (MWh). This is about twice as much as wind power, which costs about $45 to $65 per MWh, and about three times as much as solar photovoltaics (PV), which cost about $40 to $50 per MWh.
In the United States, the average price for electricity from all sources was 12 cents per kilowatt-hour (kWh) in 2018. Natural gas plants generated roughly half of U.S. electricity in 2018 at 5 cents per kWh, while coal and nuclear generated about one third each at 7 cents and 10 cents per kWh respectively.
The price of new nuclear plants in Europe has fallen by around 80% since 2007 due to economies of scale and competition with other forms of generation such as renewables and natural gas. In the UK, construction costs have fallen by 30% since 2013 with the reduction in engineering hours required for constructing reactor vessels in particular being cited as a key factor behind this fall
The cost of nuclear power depends on the cost of construction, the cost of maintaining and operating the plant, and the price of electricity.
The price of electricity is typically determined by the market, which is affected by government regulations, consumer demand and supply, and other factors.
The cost of constructing a new nuclear power plant is estimated to be between $2 billion and $10 billion per gigawatt (GW), according to the World Nuclear Association. The average cost for constructing one GW of nuclear capacity in Europe was $3.1 billion in 2016. In China, it was $2 billion in 2017.
In addition to construction costs, there are also ongoing expenses for staffing, maintenance and fuel costs. In 2016, these were estimated at $1.7 billion per year for every 10-GW capacity added worldwide.
On average, it takes about five years from start to finish before a nuclear reactor can generate electricity from its first fuel load — although this varies depending on where it’s built or what type of reactor it is (light-water reactors or heavy-water reactors).
Nuclear power is not a cheap option. It is expensive, and the cost of building a nuclear reactor is even higher. Nuclear power plants in the United States cost more than $6 billion on average to build, and many take years to complete.
The price tag for building a nuclear power plant can vary greatly depending on its size and location. Most nuclear plants are built by large corporations or public utilities, which have access to capital markets that smaller companies do not have access too.
Nuclear power plants generate electricity by using heat from nuclear fission reactions to boil water into steam that drives turbines that generate electricity. The process uses uranium fuel rods as well as cooling water from rivers or oceans to produce energy at safe levels of radiation exposure for workers and the environment.
Nuclear power costs are calculated as the capital and operating cost of the plant.
The capital cost is usually expressed in terms of a $/kW-capacity figure, which represents the total investment in building one kilowatt of capacity.
In addition to capital costs, there are operating costs associated with nuclear power generation. These include:
Fuel costs (Uranium and Plutonium)
Operating labor costs
Insurance premiums related to nuclear liability (i.e., insurance against damages caused by a nuclear accident).
