However your using a flawed metric, you need to look at cost per kWh. If you do do then you find that nuclear is one of the cleanest sources available.
First off, I am not only talking about CO2 when I talk of environmental pollution, but rather the effects of radioactive isotopes in ground water as they have been discovered as side-effects of nuclear fuel mining/processing as well as disposal. Either the technology simply isn't safe enough to prevent this, or the companies are not investing enough money because they're greedy. It's probably mostly the latter, but the end result is the same.

And the article you pulled this image from comments this image with:
Another report - Life-Cycle Energy Balance and Greenhouse Gas Emissions of Nuclear Energy in Australia - conducted by the University of Sydney in 2008 produced the following results: nuclear = 60-65 g CO2/kWh; wind power = 20 g/kWh; solar PV = 106 g/kWh. The likely range of values from this study produced the following results: nuclear = 10-130 g CO2/kWh; wind power = 13-40 g CO2/kWh; solar PV = 53-217 g CO2/kWh. Furthemore, the study criticised the Vattenfall report : "it omits the energy and greenhouse gas impacts of many upstream contributions".
It's an old trick by the nuclear industry, conveniently "forgetting" about the mining and processing and only giving numbers for plant operations. This goes both for cost as well as for pollution.
It is also worth noting that Vattenfall is a nuclear power corporation, so
probably not entirely unbiased in that matter.
Also, see this table here:

Hydro power 20
Nuclear 50
Natural gas turbines without CO2 capture 61
Onshore wind 69
Solar farms 293
Numbers are Euros per mWh.
Yes, the nuclear corporations can afford dumping prices because unlike all the other businesses they are not required to pay insurance, as nuclear power plants are virtually uninsurable.
This study by an insurance company concluded that insuring a nuclear power plant would have the price of a kilowatt-hour climb to a staggering $3.40 - compared to $0.35 from solar.
So basically, people are gambling that nothing will ever go wrong, because if it does, it's
not the company who is going to pay for clean-up.

By doing this they get the amount of waste produced to a very small number. A family of for over the course of 20 years produce an amount of waste about the size of lighter. THey have already started construction of type III breeder reactors which will reduce the amount of waste further.
The issue of course being that waste is still being produced, and that the
side-products from reprocessing are even more toxic than the original waste. I also do not know where you pulled that lighter-example from.
Added to that, reprocessing nuclear fuel is 6 times more expensive than dumping it - so what's it gonna be, paying more, thereby making this form of energy even more costly, or continueing to churn out even more radioactive waste in the thought that "a little more won't hurt", given that either method will result in waste being created?

I call groxgak on that chart. For one, it isn't even
possible to track all the number of people that have and will continue to die from radioactivity-induced cancer. Relevations such as Monticello are fairly rare, yet it would be surprising if that would be an exception - especially considering that there's even less transparency (or available means to detect such maladies) in countries like China or Russia. Added to that comes the nuclear lobby's blackout policy (and their influence in politics). Doesn't anyone remember what happened to the workers at Fukushima? Need I drag up a list of attempted cover-ups from various nuclear power plant companies around the world concerning the release of toxic substances into the environment? Studies about increased leukemia in the vicinity?
The very idea of more people supposedly dying to wind or solar energy generation than to nuclear is mind-boggling and it should be obvious that something isn't right with that chart. Where do these deaths come from, and why do they (apparently) not happen for the nuclear sector?
