The first time electricity was made by a nuclear reactor was on September, 3rd 1948 at the second reactor ever built, X-10 Graphite in Tennessee. The construction of the reactor cost $27 million. It powered up a light bulb on its first go.
The first nuclear power plant to produce electricity commercially was the APS-1 in Obninsk, Russia in 1954. It was a small scale but the biggest that was possible at the time.

Experts say:
- over the last 60 years, climate scientists say they are now virtually certain that pollution from fossil fuels has increased global temperatures.
- Emissions need to be sharply reduced to prevent more extreme damage in the future.
- The scientists acknowledge that there are risks to using nuclear power, but say those are far smaller than the risk posed by extreme climate change.

Environmental sustainability nuclear generation power
presentation
Experts say:
- more than 30 years ago James Hansen began publishing research on the threat of global warming.
- in 1998 the testimony before Congress helped launch a mainstream discussion.
- Many oppose nuclear power and believe that new forms of renewable energy will be able to power the world within the next few decades.
From Nuclear Energy to electricity
->
Nuclear Power
- Fission-Uranium atom is split into two parts, either through natural decay or when forced to within a Reactor vessel, it releases energy.
- This energy generates heat which is used to turn water into steam, the steam is then sent to rotate the turbines and generate electricity.
- The steam is then turned back into water by a lake or cooling tower.
Experts say that Nuclear is needed to slow warming:
Future Nucler power plants
- Nuclear power is a Natural supply of energy from the nucleus of atom.
- Models such as the thorium reactor that could solve the problem. thorium is abundant really hard to turn into nuclear weapons and does not take a thousand years to lose it harmful effect.
- A single ton of thorium produces the same amount of energy as 200 tons of uranium or 3.5 million tons of coal.
- Some of the world’s top climate scientists say wind and solar energy won’t be enough to head off extreme global warming.
- environmentalists are being asked to support the development of safer nuclear power as one way to cut fossil fuel pollution.
- Environmentalists agree that global warming is a threat to ecosystems and humans.
Nuclear generation power and sustainability
- A Sustained energy source is renewable and efficient source of energy, that is not depleted by use.
- nuclear fission technology is the only developed energy source that is capable of delivering the enormous quantities of energy that will be needed to run modern industrial societies safely, economically, reliably and in a sustainable way.
New Technology
Safety Issues
- Future technologies might solve the problem of nuclear waste and dangerous power plants. The nuclear reactor that we have used so far are mostly outdated technology due to nuclear innovation being stopped in the 1970s.
- Nuclear weapons- Two massive cities were destroyed by nuclear weapons.
- An international peace treaty, to use nuclear energy for peace was met after the destruction of Hiroshima and Nagasaki.
peaceful Nuclear Reactors
- transformation would reduce the global emissions of carbon dioxide profoundly, as well as cutting other significant greenhouse gases like methane.
- Methane- A colorless, odorless flammable gas that is the main constituent of natural gas.
- America has 99 nuclear power plants generating almost 20 percent of the nation’s electricity while emitting no carbon dioxide or controlled pollutants.
Safety Issues
- Nuclear waste-Nuclear fuel is radioactive and it contains poisonous chemicals,elements like plutonium.
- It was dumped in the ocean, that's been banned, now the waste is buried.
- The waste can be reprocessed and reused as fuel but the technology isn't around.
History
In 1938, scientists Otto Hahn and physicists Lise Meitner discovered what people thought was impossible: splitting a uranium atoms nucleus into two
In 1942, Enrico Fermi built the first nuclear reactor called the
Chicago - Pile 1. It was used in the Manhattan project. In the same year Fermi created the first self-controlled nuclear reaction, using a similar layout that we use today.
What Now?
Enrico Fermi discovered the ability of nuclear fission by bombarding Uranium atoms with neutrons.
Fermi and his team realized that large quantities of energy was being produced in each fission.
- Nuclear energy is reducing CO2 emissions.
- Since 1976 about 64 Gigotons of greenhouse gas emissions, have not been pumped out into the air thanks to nuclear energy.
- China already burns 4 billion tons of coal each year.
- Nations are now faced with the option of rebuilding new Nuclear reactors or shutting down, and relying on fossil foul.
After the research and developmental experiment that was the Manhattan project the idea to have the power to make energy was acknowledged.
All nuclear technology today is derived from the Manhattan project.
- Nuclear Accidents- Over 60 years of nuclear power usage there have been 7 major accidents with Nuclear reactors, dealing with nuclear waste.
- 3 were contained, 4 released radioactivity into the environment. In 1957, 1987 and in 2011 large areas of land in Russia, Ukraine and Japan were declared unfit for human habitation for decades to come.

Safety Issues
- A 2013 study conducted by NASA found that Nuclear energy has prevented approximately 1.8 million deaths, nuclear energy ranks last in death per energy unit produced.
- By reducing the amount of fossil fuel burned, countless cases of cancer lung disease and cancer can be avoided.
