Description

The global Light Water Reactors (LWRs) market size is predicted to grow from US$ 2714 million in 2025 to US$ 3877 million in 2031; it is expected to grow at a CAGR of 6.1% from 2025 to 2031.

The impact of the latest U.S. tariff measures and the corresponding policy responses from countries worldwide on market competitiveness, regional economic performance, and supply chain configurations will be comprehensively evaluated in this report.

Light water reactors (LWRs) are the most common WCRs worldwide and are divided into two types: Pressurized Water Reactors (PWRs), which produce steam for the turbine in separate steam generators; and Boiling Water Reactors (BWRs), which use the steam produced inside the reactor core directly in the steam turbine. All LWRs require fuel that is enriched in the fissile isotope, U-235.

Nuclear energy is a clean, low-carbon, high-efficiency and operationally stable form of energy, which plays an important role in guaranteeing energy security, promoting energy transformation, and contributing to the realization of carbon neutrality and climate goals. In the past two years, the global energy market has been in turmoil due to the New Crown epidemic and supply chain issues brought about by geopolitical conflicts, and countries around the world have been rethinking their energy security strategies, paying more attention to the diversity of energy sources and an autonomous and controllable energy supply. For many countries, the development of nuclear energy is a realistic option to ensure energy security. At the same time, in response to climate change, many governments have increased their ambitions and commitments to achieve net-zero emissions in recent years, and the world"s major countries have become more consistent in their goals for cleaner and low-carbon energy development. While wind and solar are expected to lead the global energy sector towards net-zero emissions, they will need to be complemented by flexible and dispatchable resources such as nuclear, due to their random volatility. Research by the International Energy Agency (IEA) suggests that global nuclear capacity will need to double by 2050 to meet the Paris Agreement"s climate change goals.2023 The International Atomic Energy Agency (IAEA) Power Reactor Information System, updated on April 19, 2023, shows that there are currently 420 nuclear reactors in operation globally, with a total installed capacity of 374,827 MWe, and 56 under construction, with a capacity of 58,595 MWe.2024 Currently, there is a total of 1.5 million nuclear power plants under construction, with a capacity of 1.5 million MWe. At present, global nuclear energy is mainly used for power generation, in addition, many countries in the world have long been practicing nuclear energy desalination, nuclear energy heating, etc. In the past two years, the world"s major nuclear power countries have made a lot of efforts in nuclear power generation. In the past two years, the world"s major nuclear power countries have made positive progress in areas such as clean hydrogen production from nuclear energy, radioisotope production and nuclear-powered ship propulsion.
