Nuclear falls over on cost comparison to just about any other power source. But only if you take into consideration the storage cost or spent uranium rods. This has to be stored in a secure area for at least a thousand years. This storage cost falls back on the public purse.
That means you and me folks will be paying for this for a thousand years plus.
Not to mention clean up costs and health costs when things go wrong. See Fukushima, that was caused by a natural disaster not human error. With a changing climate (regardless of cause). How can we make it safe?
In Fukushima for children under 10 to date, they have found 90 cases of thyroid cancer with another 500 suspected cases. They have only looked at the children. They won't look further, as the aging population is a liability. Only the children are assets and they want to see how much damage has been done to there asset values.

Jumping the gun there. From

"After studying data provided so far, including the new cancer figures, the panel said it was difficult to determine that a causal link existed between the children’s cancers and the triple meltdown at the nuclear plant."

The nuclear waste issue is a topic Greens bend around to horrify us. It's virtually a non-issue now and and breeder reactors will mitigate it to vanishing point.

Burn the transuranics in a breeder reactor, which will give America a thousand years of clean energy just with today's level of waste. (The UK has enough for 500 years clean energy).

Then vitrify it, which is melting it down into ceramic tablets!
Then dump the final fission products in the ocean!

Ocean? Yup! It’s in the book Dr James Hansen promotes! “Prescription for the planet!” (Download it free here).

This is laws of physics stuff. Radiation halves every 15 cm it travels through water. By the time you’re the height of an average man away from nuclear waste, a lethal dose of radiation has already been halved 12 times to barely detectable! There are parts of the ocean that are 6km deep. If the entire world was run on nuclear power, the true waste would only fill one barge every few years. This barge could be towed out and sunk into the deepest ocean trenches where it would sit, and maybe fry a few sea worms that crawled within 50 cm of it. Satellites could inspect the zone to make sure no vessels are after it. That’s the cheapest mechanism for high level waste. Burn it in breeders, vitrify, and dump at sea. Done.

But if you don't like that, bury it in a bunker for 300 years. Then it's safe. Done.
