The nuclear deaerator market in China is growing significantly, owing to the existence of the state-controlled and aggressive nuclear expansion program. Besides, as stated in a data report published by the EIA Government in May 2024, over a decade, over 34 GW of nuclear power capacity have been added in the country, which has successfully brought the nation’s operating nuclear reactors to 55 with an overall net capacity of 53.2 GW in April 2024. Additionally, 23 reactors are currently under construction in the country, which is also positively impacting the market’s upliftment. Moreover, there has been an upsurge in coal-based capacity by 19.5 GW in the country as of 2022, which has brought back its overall coal capacity to 1,089 GW. Additionally, the nation’s nuclear fleet comprises mostly pressurized water reactors, including the U.S. Westinghouse-designed AP1000s, constituting a 1,157 MW capacity, along with the French Orano Europe-driven Power Reactors, with 1,660 MW capacity, thereby enhancing the market’s exposure.

The nuclear deaerator market in India is also growing due to the decisive policy transition to triple the nuclear capacity as the cornerstone of its clean energy transition. As per the 2025 World Nuclear Association article, the country’s government has significantly set an ambitious target to boost nuclear capacity to almost 100 GWe by the end of 2047. In addition, at present, there are 24 operable reactors, with 7,493 Mwe capacity, of which 6 reactors are under construction, accounting for 4,768 Mwe capacity. Besides, there has been an increase in the overall operable nuclear power capacity in the country from 6,290 Mwe between 2022 and 2024 to 7,438 MWe as of 2025. Furthermore, the country comprises a population of more than 1.4 billion, based on which there is a huge demand for energy growth, which, in turn, is skyrocketing the market’s exposure.

North America Market Insights

North America in the nuclear deaerator market is projected to emerge as the fastest-growing region during the forecast duration. The market’s development in the region is highly propelled by long-lasting operation programs and tactical investment in innovative nuclear technology. Besides, in January 2024, the U.S. Department of Energy (DOE) notified the signing of the payment agreement and credit award with Pacific Gas and Electric Company to readily finalize USD 1.1 billion for credit payments through the Civil Nuclear Credit (CNC) Program. In addition, the Grid Deployment Office's Civil Nuclear Credit Program is also driving the nuclear deaerator market since it is a USD 6 billion tactical investment to assist in preserving the U.S. reactor fleet and successfully save high-paying opportunities across the region. Therefore, with the presence of such programs and investments, there is a huge opportunity for the overall nuclear deaerator market.

The U.S. in the nuclear deaerator market is gaining increased traction, owing to its association with the chemical industry’s demand for process-grade and reliable clean and steam power. The America Chemistry Council (ACC) has identified cost-effective and stabilized electricity as a severe competitive industry, with the chemical sector being considered the largest industrial customer of power. As per an article published by the U.S. Department of the Treasury in January 2025, the 48C Program, which is managed by the IRS with assistance from the Department of Energy’s (DOE) Office of Manufacturing & Energy Supply Chains (MESC), readily expanded with a USD 10 billion investment under the IRA. Of this investment, USD 10 billion, that is 40% has been effectively reserved for projects, which are designated for communities with coal plants or coal mines, thus boosting the market’s exposure.

Canada in the nuclear deaerator market is also developing due to the existence of major fleet reimbursement, along with long-lasting operation, tactical deployment of small modular reactors, along with federal policy and financial support for nuclear technology. For instance, as stated in an article published by the Ontario Government in November 2025, the Ontario Power Generation (OPG) plan has been approved by the government, based on which an increased capacity of almost 2,200 megawatts of electricity can be generated, which is equivalent to powering 2.2 million homes in the country. In addition, the project is further projected to develop an estimated 30,500 employment opportunities while effectively sustaining 6,700 jobs. Moreover, with USD 26.8 billion as the finalized budget, over 90% of the project will be spent in the nation to support economic benefits and localized businesses.

Europe Market Insights

Europe in the nuclear deaerator market is predicted to witness steady and considerable growth by the end of the projected timeline. The market’s growth in the region is highly propelled by the presence of ambitious life-extension programs, along with new-build commitments to effectively ensure energy security and significantly decarbonization objectives. Besides, the major refurbishment program in France for its reactor fleet and the UK’s support for the newest projects, such as Rolls-Royce and Sizewell C SMRs, has created a high-value and sustained demand for the nuclear deaerator market. According to an article published by Europe Institute for Security Studies in February 2025, the region has been dependent on imports for 62.5% of its overall energy supply as of 2022. At the same time, it is 97.7% of petroleum products and 97.6% for natural gas. In addition, the region has spent €448,800,000,000 on fossil fuel imports as of 2023, thereby creating a huge opportunity for expanding the nuclear deaerator market.

France in the nuclear deaerator market is gaining increased exposure, owing to the unparalleled scale of its Grand Carénage life-extension program, along with its concurrent new-build plans. As stated in an article published by Enerdata in July 2025, ASN has readily authorized the country’s EDP to ensure upgradation for its 1,300 MW reactors, which has enabled it to operate beyond the original 40-year design lifespan. This particular decision has affected 20 out of the nation’s fleet of 56 reactors, which are projected to be approved by the end of 2040. In addition, these reactors are located on sites, such as Saint-Alban, Penly, Paluel, Nogent, Golfech, Flamanville, Catternom, and Belleville, and presently these cater to over 40% of the country’s nuclear power production. Therefore, EDF has planned to readily invest €6 billion to expand their operational life, thus denoting a massive growth for the overall market.

The UK in the nuclear deaerator market is also growing due to the unique confluence of a strategic policy shift and new-build projects to significantly revive its nuclear supply chain. Besides, the government’s British Energy Security Strategy and Nuclear Energy (Financing) Act 2022 offer a financial and legalized framework that has unveiled the Regulated Asset Base (RAB) model to attract private investment for long-term projects. As per the June 2025 UK Government article, based on the government’s modern Industrial Strategy to significantly revive Britain’s industrial heartlands, the government has pledged more than £2.5 billion for the complete small-scale modular reactor program, with this particular project potentially backing up 3,000 new skilled employment opportunities. Moreover, this is poised to power the equivalent of almost 3 million homes with secured and clean homegrown energy, thereby making it suitable for the market’s upliftment.
