Nuclear reactors, large or small, are NOT “zero carbon”

On the international media, so many articles swallow the line that nuclear power, whether large or small is “zero carbon”.  In reality, nuclear reactors themselves DO emit a tiny amount of Carbon 14, – so they’re not “zero”.   But when you look at the entire chain of construction through to demolition, and the fuel chain through from mining to waste disposal, – nuclear power is a huge carbon emitter.  The whole nuclear propaganda seems now to based on this “zero carbon”story – although nuclear enthusiasts previously were often climate change deniers.   The length of time needed to set up millions of these little reactors means that they’d be irrelevant to climate change action. However, that same delay would help the coal industry to just keep on going for much longer than it should. Nuclear and coal – partners in this cover-up of the truth.

Are Small Nuclear Reactors REALLY better?

Recent experience supports skepticism. Westinghouse worked on an SMR design for a decade before giving up in 2014. Massachusetts-based Transatomic Power, a nuclear technology firm, walked away from a molten salt SMR in 2018, and despite an $111 million dollar infusion from the US government, a SMR design from Babcock & Wilcox, an advanced energy developer, folded in 2017. While the Russians have managed to get their state-funded SMR floating, its construction costs ran over estimates by four times, and its energy will cost about four times more than current US nuclear costs. 
Eventually, every nuclear conversation turns to radioactive waste and safety. SMRs using a pressurized water reactor will continue to generate highly radioactive spent fuel, yet no country has a permanent solution for how to safely store this kind of waste.  ……..
small modular reactors suffer from many of the same problems as large reactors, most notably safety issues
“It would be irresponsible for the NRC to reduce safety and security requirements for any reactor of any size.”

The Smaller Is Better Movement in Nuclear Power, Are miniature reactors really safer? Mother Jones  LOIS PARSHLEY, 8 Mar 20, 

Huge computer screens line a dark, windowless control room in Corvallis, Oregon, where engineers at the company NuScale Power hope to define the next wave of nuclear energy. Glowing icons fill the screens, representing the power output of 12 miniature nuclear reactors. Together, these small modular reactors would generate about the same amount of power as one of the conventional nuclear plants that currently dot the United States—producing enough electricity to power 540,000 homes. On the glowing screens, a palm tree indicates which of the dozen units is on “island mode,” allowing a single reactor to run disconnected from the grid in case of an emergency. 

This control room is just a mock-up, and the reactors depicted on the computer screens do not, in fact, exist. Yet NuScale has invested more than $900 million in the development of small modular reactor (SMR) technology, which the company says represents the next generation of nuclear power plants. NuScale is working on a full-scale prototype and says it is on track to break ground on its first nuclear power plant—a 720-megawatt project for a utility in Idaho—within two years; the US Nuclear Regulatory Commission has just completed the fourth phase of review of NuScale’s design, the first SMR certification the commission has reviewed. The company expect final approval by the end of 2020. The US Department of Energy has already invested $317 million in the research and development of NuScale’s SMR project.

Christiana Figueres- “Australia, you’re not ‘meeting and beating’ your emissions targets”

Be honest Australia, you’re not ‘meeting and beating’ your emissions targets https://www.smh.com.au/environment/climate-change/be-honest-australia-you-re-not-meeting-and-beating-your-emissions-targets-20200307-p547u1.html   8 Mar 20, Optimistic. Prosperous. A country of rare beauty, blessed with abundant natural resources. Australia has all the “golden eggs” needed to position itself as a global leader, to help its Asia-Pacific region leapfrog to a new energy future, and to guarantee Australian prosperity in the process.

Watching this summer’s unprecedented firestorms, I was heartbroken by the sheer scale of the human and ecological tragedy. “This must be the tipping point on climate politics in Australia,” I said to myself. “Surely now the politicians will join hands and forge a bipartisan plan for a better future.”

Instead, the climate wars have returned, driven by a handful of deniers afraid to let go of longstanding vested interests, and given air by powerful media sympathisers and a Prime Minister unwilling to fully embrace the science and stare them down.

For Australia, the choice between danger and opportunity is clear, and that choice must be made now. Since the 2008 Stern Review, the world has known that the cost of not acting is much greater than the cost of our current path. And since the 2008 Garnaut Review, Australians have known that without stronger action, droughts and bushfires would become more frequent and intense, and “observable by 2020”. It is time to move on from denial, delusion and delay towards preparedness, productivity and prosperity.

The following three steps will put Australia on track to the future we must create.

First, be honest about where Australia is at. Your country is much more than 1.3 per cent of the global climate problem. Carbon emissions from Australia’s use and export of fossil fuels account for about 5 per cent of the global fossil fuel footprint. With exports included, Australians have the biggest per capita carbon footprint in the world.

Australia is not “meeting and beating” its emissions targets. Emissions have increased in every calendar year since 2014. The government’s own projections say Australia will reduce emissions by only 16 per cent by 2030, not the 26 to 28 per cent it promised in Paris, nor the 50 per cent required by science to limit warming to 1.5 degrees. Kyoto “carryover” can’t be used to make up the gap. The Paris Agreement doesn’t allow it. To suggest otherwise is at best an attempt to paper over Australia’s lagging efforts; and at worst, a legally baseless ploy that encourages cheating and holds back development of the next phase of carbon markets.

A highly vulnerable Australia cannot address climate change on its own, but its heel dragging leaves it without the international credibility to drive a stronger global response. The Australian government must look seriously at how to really meet and beat its 2030 target, and ask other major emitters to join it in an alliance for higher ambition at the COP26 climate summit in Glasgow this November.

Second, Australia needs a bipartisan, long-term vision for decarbonisation. Rattled by the bushfires and growing evidence of climate-related risks and stresses, Australia’s biggest corporations – including Rio Tinto, Qantas, Telstra and BHP – have announced support for a national net zero target for 2050. For them, legislating this target is important to finally end the climate wars, and provide the necessary certainty to underpin investment in the transition.

All states and territories have 2050 net zero targets, as do 73 other nations, including Britain and Canada. British Prime Minister Boris Johnson would welcome Australia joining these ranks ahead of the COP26, and giving consideration to the British model of using an independent expert body to advise government on five-yearly carbon budgets en route to net zero by 2050. Independent MP Zali Steggall’s private members’ bill does exactly that.

Third, Australia must embrace net zero by 2050 as a central pillar of its economic plan for the future. The plan must prioritise the policies, industries and technologies that are scientifically aligned with the 1.5 degree temperature limit, and retire those that are not, albeit with gratitude for the service provided in the past.

Despite a booming renewables industry, coal still accounts for around 60 per cent of Australia’s energy mix. But the technology is tired and unreliable in the summer, highly polluting, and no longer price competitive with solar and wind, firmed up by big batteries or pumped hydro. There is no place for governments signed up to the Paris Agreement to provide subsidies for dying coal. We must instead invest in the future.

After two years in operation, South Australia’s 100-megawatt “big battery” at Hornsdale, has successfully stabilised the state’s grid, saved consumers $50 million, and produced handsome financial returns for its investors. In NSW, the Snowy 2.0 hydro project will deliver at least two gigawatts of dispatchable power to the main Australian grid, creating up to 5,000 jobs along the way. And for Western Australia, proponents of the 15-gigawatt wind and solar powered Asian Renewable Energy Hub plan not only to power local mines and aluminium smelters in the Pilbara. Like Chief Scientist Alan Finkel, they see the potential to earn big export dollars from green ammonia and hydrogen, displacing coal on Australia’s trade balance sheet, while quickly converting Japan and South Korea to clean energy.

These ground-breaking projects are just three examples of how Australia can lead and prosper. With political honesty and vision, ambitious targets, and a stubborn commitment to innovation, Australia stands ready to assume its rightful place as a clean energy superpower of the world. With the right choices, the future is bright.

Christiana Figueres is the former UN climate chief who oversaw the negotiation of the 2015 Paris Agreement, and is convenor of the Mission 2020 climate campaign. She is co-author of The Future We Choose and is visiting Australia this week.

Government advisers warn Britain against costly new nuclear reactors

Times 7th March 2020, Net Zero Report.  Plans for nuclear plants in Britain face fresh uncertainty after government advisers warned against backing costly new reactors. The nuclear industry wants the government to commit to a funding system to back the construction of reactors, including EDF’s proposed Sizewell plant in Suffolk.

However, the National Infrastructure Commission, set up in 2015 to provide impartial advice to the government, reiterated concerns in a report about backing more nuclear plants. It noted that there had been cost reductions in renewable power technologies such as wind and solar over the past ten years, but “costs of building and running nuclear power stations have not
fallen consistently, even in countries that have built fleets of similar reactors”. Given the potential for other non-intermittent technologies to complement renewables, it said that this “weakened the case for committing to a new fleet of nuclear power stations”.
