Jul 19, · In the early s, when the U.S. Atomic Energy Commission believed high-grade uranium ores to be in short supply domestically, it considered extracting uranium for nuclear weapons from the abundant U.S. supply of fly ash from coal burning. In , China began exploring such extraction, drawing on a pile of some million metric tons of brown-coal fly ash at Xiaolongtang in Oct 08, · Nuclear fusion, on the other hand, is based on the opposite principle. In fusion reactors, light atomic nuclei are compressed under intense pressure and heat to form heavier ones and release energy in the process. The process must be optimized to generate more energy than it consumes Mar 29, · Nuclear energy protects air quality by producing massive amounts of carbon-free electricity.

word essay on nuclear energy
Nuclear energy protects air quality by producing massive amounts of carbon-free electricity. It powers communities in 28 U. states and contributes to many non-electric applications, ranging from the medical field to space exploration. The Office of Nuclear Energy within the U. Department of Energy DOE focuses its research primarily on maintaining the existing fleet of reactors, developing new advanced reactor technologies, and improving the nuclear fuel cycle to increase the sustainability of our energy supply and strengthen the U.
Below are some of the main advantages of nuclear energy and the challenges currently facing the industry today. Nuclear is the largest source of clean power in the United States. This avoids more than million metric tons of carbon each year, essay nuclear energy, which is the equivalent of removing million cars off of the road. The thermal energy from nuclear reactors may also be used to decarbonize other energy-intensive sectors such as transportation — the largest contributor to carbon pollution.
Nuclear power plants run 24 hours a day, 7 days a week. They are designed to operate for longer stretches and refuel every 1. gross domestic product each year.
They also contribute billions of dollars annually to local economies through federal and state tax revenues. A strong civilian nuclear sector is essential to U. national security and energy diplomacy. The United States must maintain its global leadership in this arena to influence the peaceful use of nuclear technologies. The U. Commercial nuclear power is sometimes viewed by the general public as a dangerous or unstable process, essay nuclear energy.
This perception is often based on three global essay nuclear energy accidents, its false association with nuclear weapons, and how it is portrayed on popular television shows and films.
DOE and its national labs are working with industry to develop new reactors and fuels that will increase the overall performance of these technologies and reduce the amount of nuclear waste that is produced. DOE also works to provide accurate, essay nuclear energy, fact-based information about nuclear energy through its social media and STEM outreach efforts to educate the public on the benefits of nuclear energy.
Many people view used fuel as a growing problem and are apprehensive about its transportation, storage, and disposal. DOE is responsible for the eventual disposal and associated transport of all commercial used fuelwhich is currently securely stored at 76 reactor or storage sites in 34 states. For the foreseeable future, this fuel can safely remain at these facilities until a permanent disposal solution is determined by Congress.
DOE is currently evaluating nuclear power plant sites and nearby transportation infrastructure to support the eventual transport of used fuel away from these sites. It is also developing new, essay nuclear energy designed railcars to support large-scale transport of used fuel in the future.
Building a nuclear power plant can be discouraging for stakeholders. Conventional reactor designs are considered multi-billion dollar infrastructure projects. High capital costs, licensing and regulation approvals, coupled with long lead times and construction delays, have also deterred public interest. DOE is rebuilding its nuclear workforce by supporting the construction of two new reactors at Plant Vogtle in Waynesboro, Georgia.
The units are the first new reactors to begin construction in the United States in more than 30 years. The expansion project will support up to 9, workers at peak construction and create permanent jobs at the facility when the new units begin operation in and DOE is also supporting the development of smaller reactor designs, essay nuclear energy, such as microreactors essay nuclear energy small modular reactorsthat will offer even more flexibility in size and power capacity essay nuclear energy the customer.
Essay nuclear energy factory-built systems are expected to dramatically reduce construction timelines and will make nuclear more affordable to build and operate. Challenging market conditions have left the nuclear industry struggling to compete. Strict regulations on maintenance, staffing levels, operator training, and plant inspections have become a financial burden for the industry. To further improve operating costs. DOE is also working with industry to develop new fuels and cladding known as accident tolerant fuels.
These new fuels could increase plant performance, allowing for longer response times and will produce less waste. Accident tolerant fuels could gain widespread use by Office of Nuclear Energy Advantages and Challenges of Nuclear Energy. Advantages of Nuclear Energy. Clean Energy Source Nuclear is the largest source of clean power in the United States.
Most Reliable Energy Source Nuclear power plants run 24 hours a day, essay nuclear energy, 7 days a week. Supports National Security A strong civilian nuclear sector is essential to U. Challenges of Nuclear Energy. Public Awareness Commercial nuclear power is sometimes viewed by the general public essay nuclear energy a dangerous or unstable process.
Used Fuel Transportation, essay nuclear energy, Storage and Disposal Many people view used fuel as a growing problem and are apprehensive about its transportation, storage, and disposal.

Support your position with specific reasons and justifications. I think we should try to limit the use of nuclear "As a large scale low-carbon option, nuclear energy will remain in the EU power generation mix." The paper analysed five possible scenarios leading to the EU low-carbon energy economy goal by (80% reduction of CO 2 emissions), based on energy efficiency, renewables, nuclear power and carbon capture and storage (CCS). All scenarios show
