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.
White storks on road near Chernobyl, Ukraine. Many parts of the Chernobyl region have low radioactivity levels and serve as refuges for plants and animals.
How do we measure long-term impacts of nuclear accidents? Studies at Chernobyl and Fukushima show that radiation has harmed animals, birds and insects and reduced biodiversity at both sites.
Engineers have devised an innovative way to dismantle Chernobyl's reactor while preventing further radiation escaping.
Energy empire? A Gazprom facility in Moscow.
Russia's energy exports are expanding far beyond oil and gas to include coal, nuclear and refined petroleum products, a trend with far-reaching geopolitical consequences.
Temelin nuclear power plant, Czech Republic.
Recent terrorist attacks have heightened concerns about the security of nuclear plants. A former top U.S. nuclear regulator says security is weak at many sites worldwide.
The nuclear power plant in Doel, Belgium.
Evidence suggests that the threat is not being taken seriously enough.
Because knowledge is power.
Small nuclear reactors are one step closer to powering the UK's future energy requirements.
Elementary school students about 13 miles from the Fukushima Daiichi nuclear power plant walk past a geiger counter in 2012.
Remediation will never get radiation to zero in the area affected by the 2011 meltdown at the Fukushima-Daiichi nuclear power plant. Rather than safety, the conversation should focus on acceptable risk.
South Africa has made promises to decarbonise but is hugely reliable on coal - so this is difficult.
The process of decarbonisation is a complex one for South Africa, as most its power supply comes from coal.
Thousands of bags of radioactive rubble near Fukushima, 2016.
The nuclear operator was nowhere near adequately covered for the disaster. And it's not just a Japanese problem.
Under the proposed plan, countries would ship their nuclear dry storage casks to Australia.

We don't know how much it would cost to store nuclear waste in Australia - or how much other countries would be willing to pay.
South Africa hasn’t veered away from nuclear as an energy option, but President Jacob Zuma signalled a slowdown.
President Zuma indicated a welcome slowdown in the South African government's stated intention to invest in nuclear power plants.
Dr Alan Finkel will bring his perspective as an engineer to the role of Chief Scientist.

Dr Alan Finkel took over as Australia's Chief Scientist in January this year. In this exclusive interview, he describes his approach to science, and to issues such as renewable energy and STEM jobs.
George Osborne and Jim O'Neil, Commercial Secretary to the Treasury and a former Goldman Sachs investment chief, enjoy a contract signing in Beijing earlier this year.
An often ignored political role devised in 1571 tells you all you need to know about who will benefit as new power plants are built.
