(PhysOrg.com) -- After just three months of operation, the Daya Bay Reactor Neutrino Experiment has far surpassed expectations, recording tens of thousands of particle interactions and paving the way to a better understanding of neutrinos and why the universe is built of matter rather than antimatter.

Scientists at Universidad Carlos III de Madrid, Oxford University and the University of Michigan have joined efforts to develop new materials for thermonuclear fusion reactors.

A major upgrade to the DIII-D tokamak fusion reactor operated by General Atomics in San Diego will enable it to develop fusion plasmas that can burn indefinitely.

(PhysOrg.com) -- A new tool developed by nuclear engineers at Purdue University will be hitched to an experimental fusion reactor at Princeton University to learn precisely what happens when extremely hot plasmas touch and interact with the inner surface of the reactor.

The Toshiba-Westinghouse AP1000 reactor remains a symbol of the U.S. nuclear future to supporters and opponents alike

The first new nuclear reactor in the U.S. in nearly three decades is taking shape outside Augusta, Ga

On December 1, 1969, Jersey Central Power & Light initiated fission in the fuel rods of the nation's first boiling-water nuclear reactor--one of 31 ultimately built in the U.S. The first "turnkey" plant, Oyster Creek nuclear generating station in New Jersey was sold for less than $100 million in 1964--a price well below what it would ultimately cost to build the reactor. The point was to prove that a nuclear power facility could be built as cheaply as a coal-fired power plant, and the key to that was a smaller safety system

As the ongoing nuclear saga in Japan plays out, a spotlight is being thrown on the reactor technology at the heart of it.

Helicopters and fire trucks proved unsuccessful at replenishing damaged nuclear fuel pools at Japan's Fukushima Daiichi plant on Thursday. The spent-fuel pools contain a large amount of radioactive material that is not contained as well as that in the reactor cores. And although information has been spotty, nuclear experts worry that this fuel--which should be submerged in circulating water to keep it from overheating--has been at least partly exposed in the pools belonging to reactors Nos.
