How many reactors are in operation in world and in u.s

China has 51 operable nuclear reactors, with a combined net capacity of The country continues to dominate the market for new nuclear build. At the start of , 16 of the 54 reactors under construction globally were in China. China is commencing export marketing of the Hualong One, a largely indigenous reactor design. The strong impetus for developing new nuclear power in China comes from the need to improve urban air quality and reduce greenhouse gas emissions.

The government's stated long-term target, as outlined in its Energy Development Strategy Action Plan is for 58 GWe capacity by , with 30 GWe more under construction.

India has 23 operable nuclear reactors, with a combined net capacity of 6. The Indian government is committed to growing its nuclear power capacity as part of its massive infrastructure development programme. The government in set an ambitious target to have At the start of seven reactors were under construction in India, with a combined capacity of 5.

Japan has 33 operable nuclear reactors, with a combined net capacity of As of June , 10 reactors had been brought back online, with a further 15 in the process of restart approval, following the Fukushima accident in South Korea has 24 operable nuclear reactors, with a combined net capacity of South Korea has four new reactors under construction domestically as well as four in the United Arab Emirates.

It plans for two more, after which energy policy is uncertain. It is also involved in intense research on future reactor designs. Pakistan has five operable nuclear reactors, with a combined net capacity of 2. In , nuclear generated 7. Pakistan has one Chinese Hualong One unit under construction. South Africa has two operable nuclear reactors, with a combined net capacity of 1. In , nuclear generated 5.

South Africa remains committed to plans for further capacity, but financing constraints are significant. Iran has a single operable nuclear reactor with a net capacity of 0. In , nuclear generated 1. The United Arab Emirates has two operable nuclear reactors with a capacity of 2. A further two units are under construction at the same plant Barakah.

As outlined above, Bangladesh, Belarus, Turkey and the United Arab Emirates are all constructing their first nuclear power plants. A number of other countries are moving towards use of nuclear energy for power production.

Over the last 40 years the proportion of reactors reaching high capacity factors has increased significantly. It is also notable that there is no significant age-related trend in the mean capacity factor for reactors over the last five years. In addition to commercial nuclear power plants, there are about research reactors operating in over 50 countries, with more under construction.

As well as being used for research and training, many of these reactors produce medical and industrial isotopes. The use of reactors for marine propulsion is mostly confined to the major navies where it has played an important role for five decades, providing power for submarines and large surface vessels. Over ships, mostly submarines, are propelled by some nuclear reactors and over 13, reactor years of experience have been gained with marine reactors. Russia also operates a fleet of large nuclear-powered icebreakers and has more under construction.

It has also connected a floating nuclear power plant with two 32 MWe reactors to the grid in the remote arctic region of Pevek.

The reactors are adapted from those powering icebreakers. Nuclear Power in the World Today Updated October The first commercial nuclear power stations started operation in the s. Over 50 countries utilize nuclear energy in about research reactors. In addition to research, these reactors are used for the production of medical and industrial isotopes, as well as for training. Energy Information Administration EIA projects in the Annual Energy Outlook Reference case that new nuclear electricity generation capacity will be added in and , but capacity retirements and derating of some reactors will result in less total nuclear electricity generation capacity in than in Nuclear explained U.

In , reactors were operational around the world - 22 fewer than in Another 26 are currently in long-term storage and 53 are under construction - around half in China and India. The rapid expansion of renewables and negative public sentiment towards nuclear energy created by disasters such as those in Chernobyl or Fukushima have been turning nuclear power into an also-ran of global energy generation.

Nuclear power has been experiencing a slow decline from a According to the report, 33 countries currently run nuclear power reactors, but only 14 are listed as still actively pursuing the technology - including nuclear energy newcomers Belarus and the United Arab Emirates. The world's fastest growing nuclear energy program is also one of the youngest: China has used nuclear energy since the early s and currently runs 52 nuclear reactors, 39 of which joined the grid in just the past ten years.

The United States meanwhile remain the globe's biggest nuclear energy stronghold, with 93 operational reactor units as of July , down 11 since Despite the decline, the U. At currently nine active nuclear reactors, it is expected that Japan will soon officially abandon new nuclear energy construction.

Moving to clean energy is key to combating climate change, yet in the past five years, the energy transition has stagnated. Plus, improvements in the energy intensity of the global economy the amount of energy used per unit of economic activity are slowing. In energy intensity improved by 1.

Effective policies, private-sector action and public-private cooperation are needed to create a more inclusive, sustainable, affordable and secure global energy system. Benchmarking progress is essential to a successful transition.
