The nuclear industry in much of the world is struggling to survive. Reverting to small reactors may be its best hope.
Despite a campaign lasting two decades, the nuclear industry’s dream of building hundreds of large reactors to lead the fight to save the planet from overheating has evaporated.
While renewable energy industries, solar and wind in particular, get ever cheaper and expand faster, nuclear projects are steadily bogged down further in delays, cost over-runs and debt.
Some large nuclear power stations are still under construction in Russia and China, but in Europe and North America they are badly delayed and few in number. Many projects that have been long planned but not yet started are being abandoned.
This is despite the fact that nuclear-friendly governments, particularly those with nuclear-powered ships, submarines and weapons of mass destruction, have not given up on the industry.
But now, instead of building ever-larger reactors, these governments are switching their attention and financial backing to small modular reactors (SMRs).
“There is no justification for building new reactors at Sizewell C or Bradwell B”
These off-the-shelf prototypes can be scaled up or down in size, to double as power plants for ice breakers and submarines, or for use as electricity and heat generators for remote settlements, military bases and, theoretically, urban areas – if the local populations do not protest too loudly.
Currently the UK, the US, Russia and China are pouring large government subsidies into developing SMRs, which are said to be for electricity production, but equally are useful for training key personnel to use reactors for military purposes. In this regard the support of a non-nuclear weapon state (Canada) for SMRs seems odd, but it has many remote off-grid communities that might benefit if the technology works as claimed.
According to the International Atomic Energy Agency small modular reactors have a great future. Its latest report says there are 72 SMRs under development or construction in 18 countries, although large-scale deployment for the technology is still some years off.
For nuclear critics this lengthy timescale is always the problem. Solar and wind power can be deployed in a matter of months, whereas the nuclear timetables always stretch years ahead. Even then, critics wonder, will the promises made for SMRs live up to the hype? They say past experience has shown that timetables slip and costs escalate.
Time is problematic
For the moment this track record does not seem to have dampened politicians’ enthusiasm for the technology. The current promise is that once the prototypes are up and working, parts for future reactors will be made in factories and put together on-site, so reducing energy costs by mass production methods – a bit like assembly lines for cars.
Meanwhile the larger reactor-building projects are definitely in trouble. EDF, the French state-owned and debt-laden nuclear giant, the last of the big European nuclear construction companies, is currently attempting to restructure itself. The plan is to hive off its successful renewable and hydropower enterprises to separate them from its deeply troubled nuclear arm.
But, as Reuters news agency reports, these plans have run into difficulties with the European Union because of fears they may involve unfair state aid to the industry.
Even without this attempt to improve its finances by restructuring, though, EDF’s current nuclear building projects at Flamanville in France and Hinkley Point C in the west of England are behind schedule, and costs are escalating.
Flamanville is close to a decade late, and Hinkley Point’s timetable is slipping and its costs rising. Last month the Japanese giant Hitachi finally pulled the plug on its scheme to build twin reactors at Wylfa in North Wales.
Other plans by EDF and its Chinese partners to build two more French-designed giant twin reactors at Sizewell and then two Chinese reactors at Bradwell (both sites are in eastern England) are still officially going ahead. However, despite months of negotiation, neither the UK government nor the two companies have come up with a way of financing them, and opposition to both schemes is growing.
The Nuclear Free Local Authorities (NFLA) group, in a statement on the rising costs of Hinkley Point, said: “Given that renewable technologies are considerably cheaper than new nuclear, and the financial challenges of the pandemic are obvious to all, NFLA believe there needs to be an urgent rethink over the proposed ‘benefits’ of building large and highly expensive new nuclear power stations.
“In this, there is no justification for building new reactors at Sizewell C or Bradwell B.” For the nuclear industry at large, small is sounding increasingly the favoured option. − Climate News Network

Drawdown: The Most Comprehensive Plan Ever Proposed to Reverse Global Warming
by Paul Hawken and Tom Steyer
In the face of widespread fear and apathy, an international coalition of researchers, professionals, and scientists have come together to offer a set of realistic and bold solutions to climate change. One hundred techniques and practices are described here—some are well known; some you may have never heard of. They range from clean energy to educating girls in lower-income countries to land use practices that pull carbon out of the air. The solutions exist, are economically viable, and communities throughout the world are currently enacting them with skill and determination. Available On Amazon
Designing Climate Solutions: A Policy Guide for Low-Carbon Energy
by Hal Harvey, Robbie Orvis, Jeffrey Rissman
With the effects of climate change already upon us, the need to cut global greenhouse gas emissions is nothing less than urgent. It’s a daunting challenge, but the technologies and strategies to meet it exist today. A small set of energy policies, designed and implemented well, can put us on the path to a low carbon future. Energy systems are large and complex, so energy policy must be focused and cost-effective. One-size-fits-all approaches simply won’t get the job done. Policymakers need a clear, comprehensive resource that outlines the energy policies that will have the biggest impact on our climate future, and describes how to design these policies well.

This Changes Everything: Capitalism vs. The Climate
by Naomi Klein
In This Changes Everything Naomi Klein argues that climate change isn’t just another issue to be neatly filed between taxes and health care. It’s an alarm that calls us to fix an economic system that is already failing us in many ways. Klein meticulously builds the case for how massively reducing our greenhouse emissions is our best chance to simultaneously reduce gaping inequalities, re-imagine our broken democracies, and rebuild our gutted local economies. She exposes the ideological desperation of the climate-change deniers, the messianic delusions of the would-be geoengineers, and the tragic defeatism of too many mainstream green initiatives. And she demonstrates precisely why the market has not—and cannot—fix the climate crisis but will instead make things worse, with ever more extreme and ecologically damaging extraction methods, accompanied by rampant disaster capitalism.
