> No. Nuclear power creates the most dangerous waste known to mankind and we have no way of mitigating or eliminating it.
Nuclear waste is incredibly well controlled, unlike waste from solar, wind or fossil. Most Western countries didn't have contamination from civil nuclear waste at all and specially not in the last 30 years. Civilian Nuclear waste has basically killed nobody.
Calling it the 'most dangerous' is nonsense.
> Nuclear isn't cost effective on an ongoing operating basis (compared with natural gas).
Nothing is as cheap as natural gas in the US. Specially don't just look at creation but also the grid, the end to end price.
Nuclear on mass scale is very competitive and has been proven to be able to replace fossil fuels on large scales. South Korea and China can produce very competitive nuclear reactors and we could do the same in the West. France did it in the 70/80 with 1960s tech.
Nuclear has the massive advantage of being able to replace coal plants directly without redesigning the countries or even continents grid. These cost (and others) are always ignored when solar advocates claim of low dispatch cost.
> When you add the costs of closing and "cleaning up" a plant site, which run into the billions of dollars for each plant, nuclear just doesn't make sense.
Cleanup for any modern plants in the West are already part of the dispatch price. It takes a while to clean up, but the overall land use of nuclear is still 100/1000x smaller then anything else.
> Nuclear is far from "carbon neutral." The process of extracting uranium from the earth uses tremendous amounts of heavy equipment, but the carbon outputs from mining (and cleanup) are never mentioned anywhere in order to sustain the "clean power" myth.
This is another failure in understanding scale. Uranium mining is not very heavy in terms of equipment compared other mining. Furthermore Uranium has a far higher energy density then anything else we could mine for energy. Solar, Wind and literally everything else involves far more mining and far more 'gray CO2' in the production.
Nothing is zero carbon but nuclear is easily the closest thing we have. No other form of energy has a lower land use, lower resource use and produces less CO2. These are well established facts, however much anti-nuclear advocates want to ignore it.
One hand full of uranium is enough for a whole human live inclusive transportation heating and so on. Now compare this to the literal mountain of solar panels that would have to be produced (and the resource mined).

1.1 billion hectares of land are farmed to feed the 7.5 billion people. That works out to 2000 square meters per person.
World energy consumption (all sources) runs about 18 terawatts, or 2400 watts per person. That is 58kWhr per day. Using an insolation factor of 3.0 (that is a 1W solar panel averages 3Whrs per day) each person will require 20kW of solar panels to replace ALL sources of energy. That is about 100 square meters of panels per person.
That's a lot, but not unthinkable. You could buy 8 pallets of panels today for $13k and cover a person, and it only takes 5% as much land as the land used to feed that person.
I never claimed its impossible with solar, its just not very smart. Your calculation also leaves out a lot of issues with solar and intermittency. But even those things could be overcome.
However, how is that better? Uranium mining is tiny and a non issue. Thorium is even more plentiful, literally a waste product. We have enough of that stuff for 1000s of years. We have the technology to use it on mass scale and it has PROVEN track record of replacing fossil fuels at mass scales.
Solar panel waste is further duplicated by the live cycle and the lack of life cycle planning in the global supply.
The weapons lobby has nothing to do with it. The widely talked about claims that Thorium is not usable for weapons is false.
Uranium would most likely be picked for an industrial scale nuclear weapons program for a couple reasons but thorium does not eliminate these problems.
Furthermore many of the benefits people talk about when talking about Thorium is really about the reactor. Many of the same benefits could also be achieved with Uranium.
Thorium really shines for some specific reactor types.
Whats holding reactors back in general is regulation in all parts of the supply chain, from research to operational licenses, and a wide popular anti-nuclear feeling.
That is the 3.0 insolation I chose. It’s reasonably representative of areas of northern hemisphere cities. The United States average by population is probably between 4 and 5 according to this map, but winter is lower and you have to plan for that.
Northern Europeans are going to want to have some power lines to the south. Chile might be the new aluminum refining capital of the world. Africa would be energy rich.
I sometimes wonder if some of the resistance to a solar-powered world stems from their discomfort with the implied economic shift of heavy industry to brown-skinned countries.
So choose land that is poor for food production and good for electricity production, then find a way to transport the energy (one good advantage of gas/coal/oil is transportability with current infrastructure).
