About WePlanet:
WePlanet is an environmental organisation working with a network of citizen movements who are defending the crucial role of science and technology in ending the climate and biodiversity crises.
Using baseball terms. You folks at RePlanet have hit the ball out of the park! This is astoundingly, brilliant, and I have been in the pro nuclear power advocacy community for over 10 years!
Nice one Joel. Models like this work because they deal in fungibles, such as 'land' and 'energy', which all have a degree of interchangeability. Another key one, of course, is 'money'. Land has financial value, as does energy. Most things can be measured in terms of money. If environment assets have a monetary value, then is the reverse true - does money have environmental cost? i.e. if you spend a lot on something, is that having an environment consequence somewhere else in the system, or at least an opportunity cost? I don't know enough about it, but one of the key challenges with nuclear seems to be cost. To what extent would nuclear increase energy input costs to the economy? Could that be taken as a one-off 'Capex' hit by one generation for the future? Or is it an ongoing drag on everything else we do? I'd love to hear more about the cost economics of it.
Really interesting!
Excellent video. Solar PV is like 50+ times more efficient than biomass.
I'm hoping that technologies like Copenhagen Atomics comes to fruition and becomes the cheapest energy source, bar none, that actually uses existing so call nuclear waste in it's fuel cycle. Time will tell of course.
I wonder at what price electricity needs to be to make large scale vertical farming a thing. It would be great to not need to use the landscape for food production and do rewilding everywhere, with people living in smaller communities rather than in the large grey cities.
Where does the nuclear fuel come from and what area has to be mined for that fuel?
Is that just the building footprint, secure area or the owner controlled area?
Does the nuclear plant space include the space for storage of nuclear waste?
Dispense fuel, assemblies are stored on site while they cool down. Often they are then moved to dry cask storage and placed outside of the reactor complex on the grounds of the power station to await their final disposition. This can be permanent burial in a deep underground storage facility like Finland is building in the United States has or the material can be re-processed and run through a Reactor again as the French and other countries do. The solid fuel assemblies from the existing reactor fleet can also be used in advanced high temperature reactors that have been tested in the past and many are working their way through various regulatory procedures around the world like molten salt reactors.
The waste take up much less space than the plant. Usually the new hot waste is stored inside the plant, the older cool waste is stored on the site.
For bio fuel burning for electricity for the UK in 2050 you need three UK landmasses for that one year. And what are you gonna do with all the ash?
