Over the past few years, governments around the world have started turning their attention to nuclear energy again, mostly because other energetic sectors are becoming increasingly susceptible to price fluctuations on the international market. With global warming and climate change, using fossil fuels becomes an incr... |

According to a group of researchers, it may be that the earliest forms of life on the planet might have been made possible by the influence of thousands of small, nuclear fission reactors blasting everything around them with radiation. The model would account for the reason why a radioactive substance has all but dis... |

Uranium is the heaviest chemical element that can be found in nature. Over the years, scientists have been trying to discover other, heavier chemicals, and their efforts yielded plutonium in the 1940s, which went on to be used for weapons of mass destruction. Others have been discovered since, but our ability to synt... |

The Japanese Kaguya spacecraft, launched in 2007, transmitted back readings that confirmed the presence of the rare chemical uranium on the surface of the Moon. For the first time, astronomers and astrophysicists have definitive proof that an energy source for a future lunar base is readily available on the Earth... |

The city of Hanford, in Washington State, houses the oldest nuclear processing sites, and is now known as the place where weapons-grade plutonium was found lying around the dump site, enclosed only in a very shaky safe box. The find, besides eliminating a threat, also completes a piece of history, as the sample now c... |

The recent resolution of the Bush administration managed to lift the ban on the exploitation of uranium mines in the Grand Canyon. This could cause the contamination of the Colorado river's water, severe wildlife damage and increased toxicity of the area.According to the associated news release, a last year'... |

Although being the second most abundant element in the universe, making for up to 23 percent of all ordinary matter, helium is one of the most scarce elements on Earth, having a concentration averaging about 5.2 parts per million in Earth's atmosphere. Some studies even suggested that within a few years, the hel... |

On July 7, eighteen tons of uranium solution containing natural uranium have been accidentally released in the surrounding environment from one of the containment tanks of the Tricastin nuclear power plant, southern France, leading to the contamination of the ground with about 75 kilograms of unenriched nuclear mater... |

During nuclear fission reactions nuclear power plants produce a by-product element known as plutonium, which accumulates on the uranium fuel rods. Plutonium cannot occur naturally on Earth and is extremely important for the fabrication of nuclear bombs because it is used in the detonation mechanism initiating the nuc... |

The heaviest chemical element known to occur naturally in Earth's crust is uranium 92 while the heaviest chemical element known to exist, a synthetic element, bears the atomic number 118. All elements heavier than uranium are highly unstable and quickly disintegrate into other stable chemical elements - this is ... |

Not long ago, the world was dreaming of clean electric energy generated with the nuclear power plants, but you can't have nuclear power plants without nuclear fuel, can you? We're in the 21st century and we're pumping more carbon dioxide into the atmosphere than ever, despite of all the international a... |

Nuclear weapons generate high explosive energies by either fusing or splitting certain chemical elements. A new type of nuclear explosive developed by the US Department of Defense, on the other hand, uses nuclear reactions in order to determine gamma-ray emissions carrying energies about one thousand times larger tha... |

Nuclear fission reactors produce high amounts of relatively clean electric energy by burning nuclear fuels, such as uranium. Higher-efficiency nuclear fuel is required for the next generation of nuclear reactors, which will burn longer and stronger to produce even higher amounts of energy. However, researchers say th... |

Uranium dioxide is the world's most common radioactive substance, alongside the natural uranium molecule. Most of this nuclear waste results in the nuclear reactors of the nuclear power plants, during the process of nuclear fission, or nuclear fuel 'burning', which involves splitting the uranium atom t... |

There is only one word on everyone's lips today: energy. And how to produce it more efficiently, without polluting the planet. The International Thermonuclear Experimental Reactor, or ITER for short, has recently received a contribution of 1.4 billion dollars from the Republic of China, which covers about 10 pe... |

There is a general misconception that nuclear power plants produce dangerous levels of radiation during their electric energy production activity, or that they are just another disaster waiting to happen. The truth is that aside the fact that they produce energy in an extremely efficient manner, without emitting any ... |

Nuclear waste is remnant radioactive material resulted from the nuclear weapons program, or from processing in the nuclear power plants, which cannot be further used for other industrial activities. It is usually extremely radioactive, and has half life time in the range of millions of years, thus a solution must be ... |

Opal is one of the most precious gemstones people prefer. Scientists believe that the beautiful display of color this precious stone shows is mainly due to tiny amounts of uranium present in the composition of the stone. This discovery could prove to be valuable information for the artificial opal industry.The disco... |

The new molecule designed at the University of Virginia is the first uranium methylidyne ever reported, containing an uranium-carbon triple-bond. A methylidyne or methine as it is also known is a tri-valent functional group CH, derived from methane. The methine group consists of a carbon atom with two single bounds a... |

The U.S Department of Energy has started a three-year project which will research the creation of a new generation of computers for a new kind of nuclear reactor, proposed by physics professor Michael Podowski. The reactor is called a sodium-cooled fast reactor, of SFR for short.Nuclear reactors are mainly used in nu... |

A high flux isotope reactor went online after more than a year of repairs, systems checks and improvements that cost more that $70 million. It's a research reactor at the Department of Energy's Oak Ridge National Laboratory internationally recognized as a neutron source for materials studies and isotope pr... |
