I assume that you're arguing the reverse of what you actually have written, that is, you wanted to write "What makes nuclear so much better than nuclear..." I make the inference because of your last sentence.
I cover this subject over and over and over again, and the answer doesn't really change.
The difference between PV and solar is economic cost (direct costs) and external costs. Nuclear power is cheaper in direct terms by a factor of four or five, which is why the world is building 31 nuclear plants today and no body (without a subsidy) is installing equivalent PV capacity. Because the sun refuses to shine at night, it is necessary to create storage systems with PV, and these systems, further add to the costs.
Because solar systems require a huge amount of mass per watt generated relative to nuclear, the environmental cost (metals mined and refined) energy invested in manufacture, hazardous chemicals used, makes the external cost of solar energy higher than nuclear. This also extends to the area of "waste" (for instance cadmium mine tailings, sulfates from the roasting cadmium ores) of solar energy. Since more mass must be processed for these purposes, the waste is corresponding more difficult to contain.
I do recognize that people often appeal to so called "nuclear wastes" as an argument against nuclear power because, as is frequently alleged "there is no solution for nuclear waste." At this point in the conversation I ask the question: "Can you name a form of energy for which "waste" problems have been solved?" No one ever gives a satisfactory answer to this question, which is another way of saying "nuclear waste is worse than other worst because it is spelled with a N, a U, a C, an L, an E, an A and an R.
I have frequently bumped up a thread (of my own creation) on this site entitled "The External Cost of Energy: What You Pay With Your Flesh," that is built around an elaborate EU study showing that the environmental cost of the wastes associated with all other forms of energy (other than wind) are much higher than the costs of nuclear waste. There were recent Finnish and Swiss studies that came to the same surprising (to some) conclusion.
I sometimes ask people to show a case of a person who has been killed by the storage of commercial "nuclear waste." No one ever takes me up on this challenge. I would love to hear of such an incident, although I am likely to point out that millions of people are killed each year (largely unmourned) by air pollution. So what I am really asking for is a demonstration of deaths from nuclear waste, which produces very little air pollution, with deaths from other forms of energy which produce do significant air pollution. (Please note: The greenhouse gas costs of building nuclear plants are significantly smaller gram per watt than the costs of manufacturing PV cells.)
Sometimes in this argument, I also point out that what is defined as "nuclear waste," is only usually regarded as "waste" in the United States. In most other places, the so called "waste" is actually recognized for what it is, an enormous resource. In a recent thread for instance, I noted that Japan plans to market the Ruthenium, Rhodium and Palladium obtained from it's so called "nuclear waste," and collect hundreds of millions of dollars in the process. (The world supply of Rhodium found in ores is dwarfed by the supply of Rhodium in so called "nuclear waste.") I note too that 97% of what is in so called "nuclear waste" is pretty much the same Uranium that came out of the ground. This material is recyclable and contains vast amounts of energy.
However, all this said, I believe we have a responsibility to embrace as many solar energy systems as are economically and environmentally feasible. First, all are preferable to oil and coal. Second, nuclear fission resources are not infinite. They will last only for a few millenia. Therefore it is selfish and morally indifferent to simply consume these resources because they are there and immediately convenient, as previous generations have done with oil. It is true that we will have to pay a higher environmental cost for the use of most forms of solar energy than we would if we limited ourselves to nuclear fission. But it is completely self serving to insist that future generations, our decedents, our children pay these costs because we are unwilling to pay them ourselves. Someone will have to pay the burden, and we should share it among all generations. If we use solar energy, we can conceivably make nuclear resources available for tens of thousands of years, rather than the two or three thousand years they would last if we simply fulfilled all of our energy needs with nuclear energy.
In this sense I agree with you.
