Climate action? – you simply couldn’t build enough nuclear reactors
New Scientist 26th Feb 2020, Paul Dorfman, University College London Energy Institute, UK; Tom Burke,E3G; Steve Thomas, University of Greenwich, UK; Jonathan Porritt,
environmental campaigner; and David Lowry, Institute for Resource and
Security Studies. Reporting the decline of nuclear power generation, you
quote Michael Shellenberger’s view that nuclear power is necessary to
prevent climate change (8 February, p 20).
This view is truly dangerous. Climate change poses a number of unique challenges to humanity. One of the most difficult is that the world not only needs to get to a specific place
– a carbon-neutral global energy system – but also must get there by a specific time – the middle of the century. Otherwise the policy fails.
You simply couldn’t build enough nuclear reactors fast enough, even to
replace the existing reactors that will reach the end of their life by
2050, let alone to replace fossil fuels in the existing electricity system
or in the more electricity-intensive global economy we are currently
building. This would be true even if we were willing and able to overcome
all the other unsolved problems that nuclear reactors face. These include
their affordability, accidents, waste management, nuclear weapons
proliferation, the scarcity of talent and system inflexibility.
