Fusion power, if it works, offers vast amounts of clean energy and almost zero carbon emissions. A new experimental fusion reactor has come online, and it uses a curious twisted stellarator design.
In Switzerland, specific and often costly environmental policies are put to test through direct democracy.
The Fukushima Daini plant, 11km from the ill-fated Daiichi station, suffered a technical problem in one of its spent fuel cooling ponds.
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.

After a Royal Commission and a citizens' jury, South Australian Premier Jay Weatherill has enough advice to decide on his nuclear waste dump plan. Which makes his decision to hold a plebiscite baffling.
Koeberg is South Africa’s only nuclear power station but that may change in the future.
There are fears that that the nuclear build in South Africa is being driven for the benefit of the politically connected rather than the national good.
Controversy dogs South Africa’s nuclear energy plans.
South Africa's Parliamentary Budget Office had 10 months to prepare its findings about the cost of a nuclear programme. Its final report was little more than a summary of other institutions' work.
The country needs more nuclear power – but not more Hinkleys.

The decision to review Hinkley Point C was carried out in a way that quite unnecessarily put Britain’s future relations with China in jeopardy.
Will nuclear subsidies stifle competition?
A former state regulator and member of the U.S. Nuclear Regulatory Commission argues that subsidizing reactors to keep them running is unnecessary and will be bad for consumers and the environment.
The FitzPatrick nuclear plant in Oswego, New York will receive state subsidies to continue operating through 2029.

The anti-nuclear movement in the U.S. is at a critical juncture as worries over climate change grow.
Protesters gathered near the proposed site for Hinkley Point C.
For years UK energy policy has been focused on creating a perfect environment for a new nuclear plant. Now things just got exciting.
Hinkley Point B was built in the 1970s. The proposed plant, Hinkley C, will be built next door.

Britain should focus on energy efficiency and small-scale renewable projects, not huge new power plants.
Dry nuclear fuel casks similar to those Australia would use to store nuclear waste temporarily above ground.
The South Australian royal commission recommended the state investigate a high-level nuclear storage facility. But the costs don't stack up.
The Greens are the party of climate action - but do they embrace enough technologies to get there?

The Greens have successfully cast themselves as the party of climate science. But to hit their climate goals they may need to become even more radical, by embracing technologies like nuclear power.
The biggest concern is that nuclear power is too expensive for South Africa and investing in it will cripple the economy.
South Africa's nuclear plans have been put on hold. In light of recent events in the country, pressure is being put on the government to halt the process.
Australia could take spent fuel from nuclear power stations overseas. This one is in South Korea.
South Australia's Nuclear Fuel Cycle Royal Commission has recommended a nuclear waste site for the state.
Rouhani and Renzi meet in Rome.
The most difficult aspect of trade in "post-sanctions" Tehran, is how to navigate the sanctions still in place.
Radiation exposure as a child can increase cancer risk later in life. But by how much?
Chernobyl is already responsible for up to 5,000 cases of cancer in Europe.
After one reactor at the Chernobyl nuclear power plant caught fire and exploded in 1986, the whole site was encased in a concrete sarcophagus.
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.
