Exporting nuclear technology is lucrative, but without strict safeguards, buyers could divert it into bomb programs. Why is Saudi Arabia shopping for nuclear power, and should the US provide it?
Lessons learned from Hurricane Andrew in 1992 and the Fukushima disaster in 2011 have changed how utilities brace for big storms.
Advanced small modular reactors, known as SMRs, will probably have many advantages over older technology. But it's not yet known how they will stack up against other sources of electricity.
If recent history repeats itself, the proposed repository for extremely dangerous nuclear waste will stay dead.
By figuring out fission, physicists were able to split uranium atoms and release massive amounts of energy. This Manhattan Project work paved the way both for atomic bombs and nuclear power reactors.
A nuclear physicist and disarmament expert recommends reading on nuclear disasters, weapons, authoritarianism and climate change.
Nuclear power plants don't just pump out steady, carbon-free electricity; they also help produce the people the US needs for nuclear weapons inspections.
Nuclear industry players tout small modular reactors as an "inherently safe," cost-effective source of electricity. The reality may be less attractive.
Vietnam recently cancelled it's plans for the procurement of nuclear energy. There are lessons South Africa can take from this.
The latest earthquake off Japan's east coast was an ominous reminder of the 2011 Fukushima disaster. But despite a technical hitch at one of Fukushima's other reactors, there was no repeat this time.
This is a big opportunity for smaller reactors that can be built quickly and cheaply.
Chernobyl is already responsible for up to 5,000 cases of cancer in Europe.
The meltdown at the Chernobyl Nuclear Power Plant in 1986 exposed 572 million people to radiation. No other nuclear accident holds a candle to that level of public health impact.
Engineers have devised an innovative way to dismantle Chernobyl's reactor while preventing further radiation escaping.
The UK government looks set to allow EDF to build a new kind of nuclear reactor at Hinkley Point. But are there better nuclear technologies we could use?
The restart of Japan's nuclear reactors is good news for climate change. But there are still large psychological barriers to overcome.
Even the biggest proponents of nuclear power can't ignore 10,000 metric tons of spent fuel globally every year. What if we could recycle every last atom of nuclear waste?
The basics of fission physics have stayed the same over the decades. But power-generating reactor designs have evolved, turning to new coolants, recycled fuel and other innovations.
It’s been almost two decades since a new nuclear plant opened for business in the United States. But that’s about to change as construction wraps up on the Tennessee Valley Authority’s Watts Bar Unit 2…
