Nuclear fusion is the safest way to create power. It involves putting two atoms together to make one. The technology has never been implemented on a broad scale, so almost all nuclear power plants use nuclear fission – which splits one atom into two, and is considered more dangerous.

Every year and a half to two years, every nuclear plant goes through a cleaning cycle that shuts down the plant to allow for the removal of radioactive waste.

The first developed country to follow through on the agreements to destroy nuclear weapon stockpiles and cease production of nuclear weapons was South Africa. A newcomer to nuclear warfare, they had only developed nuclear weapons in the late 80s.

The former Soviet Union was “helped” by the US to create their first nuclear weapons. A successful spy venture stole them the information they needed to complete their program from the Los Alamo laboratories in the US that created nuclear weaponry.

The largest nuclear reactor is actually the Sun. It uses nuclear reactions, a natural process, to convert hydrogen to helium.

While concern about exposure to radiation is valid, some research shows that you will get more radiation over your lifetime from being around personal electronics than from being near a nuclear power plant.

The US tests their nuclear weapons in Nevada and in the Pacific Proving Grounds. The Proving Grounds cover the Marshall Islands.

Tsar Bomba, from the former Soviet Union, remains the most powerful nuclear device ever created. It was tested in 1961 over Novaya Zemlya. And the mushroom cloud it produced could be seen clearly from over 600 miles

There are 4 different tests used in developing a nuclear weapon. They are the atmospheric and underwater test, as well as the exoatmospheric and underground tests.

Nuclear energy is the energy stored in the nucleus of an atom. It can be used to produce electricity. But, before it can used, it must be released. The enormous energy that is stored in the bonds that hold atoms together can be released by two processes: nuclear fission or nuclear fusion

The US has concerns about two points in ongoing world crises that have the potential to lead to a nuclear war. The first is featured in the conflict between India and Pakistan; the second is the conflict over China and Taiwan, which would also involve the US.

In nuclear fission, atoms are split to form smaller atoms, releasing energy whereas in nuclear fusion atoms are combined or fused to form a larger atom. This is how the sun produces energy

The process to produce electricity from nuclear reactor is similar to most types of reactor. The only difference is that “chain reaction” is used to produce the heat. Nuclear power plants use nuclear fission to produce electricity.

In the event of a disaster, should you be exposed to nuclear material – remove all of your clothes. This will also remove almost 90% of the radioactive material you were just exposed too.

A nuclear power reactor uses uranium rods as nuclear fuel to generate heat that will be used to generate electricity. Carbon dioxide and water is then used to take the heat away to produce steam and generate electricity. The steam then turn turbines which drive generators.

The event at Fukushima in 2011 led to many countries stopping plans for increased nuclear power plants, while others are staying on track. It should be noted that growing countries, such as China and India, are still pursuing nuclear power.

The event at Fukushima also caused a downgrade and the predicted amount of energy that nuclear plants would provide to the global economy. This has led to concerns over what could be used to fill the gap in need by 2035.

: Most people don’t realize that over 20-percent of the US electricity is provided by nuclear power. There are just over 100 nuclear power plants in operation in the country. The earliest came on long before 1979. Despite their presence and contribution to the country’s support, no new plants have been built since the 1979 and the Three Mile Island incident.

While the process of getting all of the materials to build a nuclear plant created environmental pollution, and nuclear waste is an issue – the process of using nuclear energy and producing it has no significant environmental impact. Using fossil fuels contributes to pollution at every stage of production and use

Shearon Harris in North Carolina is one of the primary areas that Homeland Security is securing against terrorist attacks. It has the largest nuclear waste storage pool in the country.

Worldwide, there are over 400 commercial nuclear reactors producing energy for 31 countries.

It can cost over 6 billion dollars to build one new reactor for an existing plant.

In the entire history of nuclear energy production, there have only been 3 major disasters – Three Mile Island, Fukushima, and Chernobyl. In the past 25 years, there have been over 10 major disasters with fossil fuel energy – the largest of which was the BP oil spill.

The largest surface nuclear powered ship is not only over 50 years old, it’s still in service. The USS Enterprise was put into service in 1960 and is 1,122 feet long.

The former Soviet Union was the first world power to use nuclear energy to produce electrical power. The Obninsk Power Plant came online in 1954.
