Nuclear Power Market Size, Share, Growth, Analysis

The main dirver is Increasing nuclear power projects with countries catching on to the fact that nuclear energy can help deal with the challenges of energy security and climate change, more demand for clean energy propels the nuclear power market. Nuclear Energy Project in the World According to projections by the International Atomic Energy Agency, the global nuclear capacity has upwardly revised; by 2050, it points to an increase of 25% above previously done projections that were based on estimations from 2020. Several countries have begun to understand and recognize its position as an important solution to many problems concerning energy security and climate change. In the light of the increasing worldwide consensus of nations toward nuclear power as a low-carbon, reliable source of energy to be used in the attainment of decarbonization goals and complementing energy security in response to volatile fossil fuel prices and geopolitical tensions. Nuclear power delivers about 10 percent of the electricity in the world and as of July 2024, about 20 percent of Europe, according to the World Nuclear Association. This production is important in curbing carbon emissions since, traditionally, it is one of the biggest sources of carbon-free electricity.

Nuclear power plants are among the most capital-intensive sources of electricity. This means high initial capital and maintenance costs. Capital costs, including financing (at a high discount rate), for nuclear power for a 2,200 MWe plant range between USD 3,000 and USD 4,000 per kilowatt. LCOE varies from USD 129/MWh to USD 198/MWh, considering specific factors like a particular location, the regulatory environment applicable at that location, and a specific technology. This immense amount of spending is primarily attributed to its complex engineering and safety systems; in fact, such long lifetimes, up to 60 years, can easily compromise its safe operation. The maintenance costs of nuclear power plants are relatively lower compared to their initial capital costs. Once operational, these facilities usually have low and stable operational costs. However, maintenance would include rigorous safety checks and regulatory compliance measures that may still incur significant costs over time. Decommissioning at the end of a plant's life cycle also adds to the financial burden, estimated to be around 9 to 15% of the initial capital cost. Another critical factor that determines the economics of nuclear power is the financing structure.

Nuclear-renewable hybrid energy systems (NRHES) are a new way of combining nuclear power with renewable sources such as solar, wind, or hydropower to provide the greatest strength for both. Such systems go a long way in solving some of the key issues in the energy transition, particularly regarding reliability, sustainability, and decarbonization across sectors. The system can offer constant baseload power to supplement the variability of the renewable source, whose generation varies with the weather. Coupling these sources of energy, NRHES assures a grid with a constant electricity supply regardless of low renewable generation time. Hybrid systems can supplement these sectors, which include industrial processes, desalination, and hydrogen production to add low-carbon energy to electricity grids. Small modular reactors are core to the hybrid systems. This serves as a low-carbon replacement to aging fossil fuel plants while incorporating some 50 concepts under development worldwide for small modular reactors, which are designed suitable both for electric and non-electric applications, heating included with water desalination so as to stabilize grids at a lesser cost of a low carbon transition. Other nuclear-renewable systems are being ventured at Idaho National Laboratory (INL) to power hydrogen production integrated with the intermittent usage of the resources.

Decommissioning and upgrading are serious problems facing the nuclear power market. Decommissioning is defined as decontamination followed by the step-by-step removal of a nuclear plant by an owner who intends to retire it. Decommissioning involves defueling, followed by coolant removal; the NRC defines it, however, as starting only when such elements are removed from a decommissioned plant. Its process ends with license revocation after verification of successful decontamination and waste removal. According to the IAEA, the decommissioning and waste management of a nuclear reactor will cost about USD 500 million to USD 2 billion by April 2023. The decommissioning of gas-cooled graphite-moderated reactors is costlier than that of pressurized or boiling water reactors as they are larger and more complicated in size. For large fuel cycle facilities such as spent fuel reprocessors, decommissioning costs come in the range of about 4 billion USD to be completed over more than 30 years. It will cost over 20 million USD and take between 5 to 10 years to decommission a research reactor that has a thermal output of 10 megawatts; this would depend upon other factors, such as the size and purpose of the reactor and its operating history.
