Forensic investigation of uranium from German nuclear projects from the 1940s

In Germany in the 1940s, a variety of projects was launched to develop technical applications for the nuclear fission of uranium. Historical uranium samples from Germany have now undergone forensic investigation by an international ...

Neutrons find 'missing' magnetism of plutonium

Groundbreaking work at two Department of Energy national laboratories has confirmed plutonium's magnetism, which scientists have long theorized but have never been able to experimentally observe. The advances that enabled ...

A brief history of nukes in space

In just a few short weeks, NASA's New Horizons spacecraft will make its historic flyby of Pluto and its moons. Solar panels are unable to operate in the dim nether regions of the outer solar system, and instead, New Horizons ...

Harvesting usable fuel from nuclear waste – and dealing with the last chemical troublemakers

Nuclear energy provides about 11% of the world's total electricity today. This power source produces no carbon dioxide during plant operation, meaning it doesn't contribute to climate change via greenhouse gas emissions. ...

A new chapter in Earth history

An international group of scientists has proposed that fallout from hundreds of nuclear weapons tests in the late 1940s to early 1960s could be used to mark the dawn of a new geological age in Earth history – the Anthropocene.

Getting a critical edge on plutonium identification

A collaboration between NIST scientists and colleagues at Los Alamos National Laboratory (LANL) has resulted in a new kind of sensor that can be used to investigate the telltale isotopic composition of plutonium samples – ...

A long journey toward advanced nuclear fuels

After years of waiting, a trans-Atlantic voyage and a cross-country trip, a cask containing four experimental irradiated pins of nuclear fuel arrived at DOE's Idaho National Laboratory in late July. The pins traveled from ...

Antineutrino detectors could aid non-proliferation

Physicists at the Large Hadron Collider in Switzerland and even in the fictional world of CBS' "The Big Bang Theory" look to subatomic particles called neutrinos to answer the big questions about the universe.

Using antineutrinos to monitor nuclear reactors

When monitoring nuclear reactors, the International Atomic Energy Agency has to rely on input given by the operators. In the future, antineutrino detectors may provide an additional option for monitoring. However, heretofore ...

Debunking myths on nuclear power

It is the received wisdom that nuclear weapons and nuclear power are inseparable. Consequently, any country that builds a civilian nuclear power station is able to build an atomic bomb within a couple of years.
