Nuclear reactor issues

Nuclear reactor issues

Preface.  There are half a dozen articles below. Although safety and disposal of nuclear waste ought to be the main reasons why no more plants should be built, what will really stop them isbecause it takes years to get permits and $8.5–$20 billion in capital must be raised for a new 3400 MW nuclear power plant (O’Grady 2008). This is almost impossible when a much cheaper and much safer 3400 MW natural gas plant can be built for $2.5 billion in half the time or less.

U.S. nuclear power plants are old and in decline. By 2030, U.S. nuclear power generation might be the source of just 10% of electricity, half of their 20% production of electricity now, because 38 reactors producing a third of nuclear power are past their 40-year life span, and another 33 reactors producing a third of nuclear power are over 30 years old. Although some will have their licenses extended, 37 reactors that produce half of nuclear power are at risk of closing because of economics, breakdowns, unreliability, long outages, safety, and expensive post-Fukushima retrofits (Cooper 2013).

If you’ve read the nuclear reactor hazards paper or my summary of it, then you understand why there will continually be accidents like Fukushima and Chernobyl.  That makes investors and governments fearful of spending billions of dollars to build nuclear plants.

Nor will people be willing to use precious oil as it declines to build a nuclear power plant that could take up to 10 years to build, when that oil will be more needed for tractors to plant and harvest food and trucks to deliver the food to cities (electric power can’t do that, tractors and trucks have to run on oil).

And if we are dumb enough to try, we’ll smack into the brick wall of Peak Uranium.

Peak Uranium by Ugo Bardi from Extracted: How the Quest for Mineral Wealth Is Plundering the Planet

Peak Uranium by Ugo Bardi from Extracted: How the Quest for Mineral Wealth Is Plundering the Planet

Figure 1. cumulative uranium consumption by IPCC model 2015-2100 versus measured and inferred Uranium resources

[ Figure 1 shows that the next IPCC report counts very much on nuclear power to keep warming below 2.5 C.  The black line represents how many million tonnes of reasonably and inferred resources under $260 per kg remain (2016 IAEA redbook). Clearly most of the IPCC models are unrealistic.  The IPCC greatly exaggerates the amount of oil and coal reserves as well. Source: David Hughes (private communication)

This is an extract of Ugo Bardi’s must read “Extracted” about the limits of production of uranium.

Many well-meaning citizens favor nuclear power because it doesn’t emit greenhouse gases.  The problem is that the Achilles heel of civilization is our dependency on trucks of all kinds, which run on diesel fuel because diesel engines transformed our civilization with their ability to do heavy work better than steam, gasoline, or any other kind of engine.  Trucks are required to keep the supply chains going that every person and business on earth require, from food to the materials and construction of the roads they run on, as well as mining, agriculture, construction trucks, logging etc.  

Nuclear power plants are not a solution, since trucks can’t run on electricity, so anything that generates electricity is not a solution, nor is it likely that the electric grid can ever be 100% renewable (read “When trucks stop running”, this can’t be explained in a sound-bite).  And we certainly aren’t going to be able to replace a billion trucks and equipment with diesel engines by the time the energy crunch hits with something else, there is nothing else.
