The European Commission Joint Research Centre (JRC) is among the few laboratories in the world that can provide the highly specialized analytical methods and techniques needed for nuclear safeguards and forensics purposes. In Europe, the JRC's Institute for Transuranium Elements (JRC-ITU) supports Euratom Safeguards, whose mission is to ensure that within the EU, nuclear material is not diverted from its intended use and that safeguarding obligations agreed with third parties are complied...

A bottle found at a dumpsite has the oldest example of plutonium prepared in a nuclear reactor, scientists announced yesterday. The sample is from 1944 and is an artifact from the early years of the US nuclear weapons program. Scientists from the Pacific Northwest National Laboratory utilized nuclear forensic methods to precisely date and find the origins of the sample. The researchers have labeled this "nuclear archaeology." The bottle of plutonium was found in a trench at the Hanford...

U.S. physicists say they've designed a system that would use fusion to eliminate most toxic waste produced by nuclear power plants. The University of Texas at Austin scientists said their invention -- called the Super X Divertor -- when fully developed, could help combat global warming by making nuclear power cleaner and a more viable replacement of carbon-heavy energy sources, such as coal. We have created a way to use fusion to relatively inexpensively destroy the waste from nuclear...

Physicists at The University of Texas at Austin have designed a new system that, when fully developed, would use fusion to eliminate most of the transuranic waste produced by nuclear power plants. The invention could help combat global warming by making nuclear power cleaner and thus a more viable replacement of carbon-heavy energy sources, such as coal. "We have created a way to use fusion to relatively inexpensively destroy the waste from nuclear fission," says Mike Kotschenreuther, senior...

Nuclear power could make a comeback beyond Earth if NASA goes forward with a proposed a fission reactor in its future moon base. A fission-powered system could generate up to 40 kilowatts and give any lunar outpost enough power to supply eight houses on Earth. More importantly, astronauts will require a reliable and steady energy source on the moon and Mars. "The problem with power on the moon is that, depending on where you're located, you may have 14 days of darkness," said Lee...

NASA astronauts will need power sources when they return to the moon and establish a lunar outpost. NASA engineers are exploring the possibility of nuclear fission to provide the necessary power and taking initial steps toward a non-nuclear technology demonstration of this type of system. A fission surface power system on the moon has the potential to generate a steady 40 kilowatts of electric power, enough for about eight houses on Earth. It works by splitting uranium atoms in a reactor to...

By Little, Joseph This article examines the role of the liquid drop analogy in George Gamow's theory of nuclear structure and his subsequent derivation of nuclear energy. It argues that the correspondences constituting the analogy served distinct but cooperative ends, requiring Gamow to posit a relatively simple nuclear geometry that set him apart from his contemporaries, mostly shell theorists, and led to his successful derivation of nuclear energy in the fall of 1928. Analogy has long...


Word of the Day
cruet
  • A vial or small glass bottle, especially one for holding vinegar, oil, etc.; a caster for liquids.
This word is Middle English in origin, and ultimately comes from the Old French, diminutive of 'crue,' flask.
