While germany is getting out of nuclear power altogether... their "Energiewende" plan is very ambitious but i wonder if its not better to invest into nuclear power to make it saver instead of getting rid of it completely. I dont know much about it though, what do experts think?

Is that an offer to pay all the external costs of nuclear power? I mean, all of them. From final deposit, over insurance policies in case of a meltdown to environmental consequences of the entire nuclear supply chain? Nuclear power is just too expensive for an economy. Nuclear power is limited, there is just not endless amount of uranium on the planet. Also globally nuclear power is pointless, IIRC nuclear power has a global market share of 6% for primary energy. Too believe it could solve our energy needs sounds weird to me. Also nuclear power is inefficient. Efficiency is usually way below 50%, since nuclear power plants are far away from anything you can't usually use the heat an nuclear power plant produce for anything productive, so it's lost. But of course there are new and better plants in development, they are safer and bigger and produce less waste. But the old plants still exist. You can't replace them within a few years, it takes decades. And the costs for such a programme will be very high. Since 2005, there is a nuclear power plant being build in Finland, called Olkiluoto III. The reactor was priced at three billion euros, currently the price increased to about six billion. The reactor might go online in 2015, a decade after the construction started. The reactor will provide 1600 MW of electrical power. For comparison, in 2011 alone wind power plants were build with the combined power of 9600 MW (Europe wide, Germany about 2000 MW, GB about 1300 MW). I know, this is not directly comparable but it gives you a hint, that you could have easily get the 1600 MW in ten years with renewable sources. Nuclear power might be an interesting technology, but for me it is just a steam machine, which leaves a huge pile of waste behind. Nobody knows how to handle it, and people got it wrong. Search for Asse II if you want to know more about it. For Germany it will be very hard to find a safe final deposit for all the nuclear waste.

  I think many nuke advocates go much too far in the "nuclear power will solve all our problems!" That said, the strongest arguments for nuclear power has always been as part of a balanced energy diet, not as the off the shelf answer to everything. So, how do we figure out where it's appropriate and where not? Properly price carbon, and remove all distorting subsidies to all forms of energy, from fossil fuels to solar to wind to nuclear. Then let the market do what it does best: figure out the best way to allocate capital to produce goods. Nuclear certainly needs proper regulation and safety requirements, but contemporary designs are much lower risk than the Fukushima reactor from the 1970s or the ancient design of Chernobyl: despite that, they're nearly impossible to build. I've heard it wouldn't even be allowed, in the current regulatory regime, to replace those old plants with new ones. Something's broken there.

    Dear fellow free market enthusiast, I fear it is not possible to determine a price for the storage of nuclear waste, because it needs to be taken care of so long. If one could estimate a price, I would doubt that any of todays companies companies is yet big enough to pay for it. If you look at germany for instance: We are using nuclear power since decades, in almost 20 plants. Yet there is no solution for waste storage, so far. And it will be society paying for it, not the companies.

      Coal plants also produce nuclear waste. It either goes with the smoke or is filtered. What do they do with the filters though?

        The activity of those filters is so low, that burying it a couple of meters into the ground works well.

Germans have more than one goals: more renewable energy (to replace conventional power plants) AND no nuclear. The latter is not optional.
