Could the US Phase Out Nuclear Power? 657
mdsolar writes "In the wake of the Fukushima nuclear disaster in Japan, [German Chancellor] Merkel announced that her country would close all of its 17 existing reactors by 2022. Other nations, including Japan, Italy, and Switzerland, have announced plans to pare back nuclear power, but none have gone as far as Germany, the world's fourth-largest economy. Merkel vows to replace nuclear power with alternatives that do not increase greenhouse gases or shackle the economic growth. Could the US do the same? An increasing number of reports suggest it is not beyond the realm of possibility, and Germany could provide a road map."

Nuclear has lower operational impacts than coal. Coal has lower failure impacts than Nuclear.
Operational impacts can be planned for and reasonably dealt with. Failure impacts cannot. At some point the level of planning fails because of unforeseen risks. You can mitigate as best as possible, but you can never solve the problem with certainty.
Solar/wind is lower than either on both accounts. The energy 'storage' technology isn't yet ready for wind/solar to be grid scale but it is coming.

Coal power is a major polluter, both air AND soil/water. Look at the Kingston fly ash spill...
Natural gas may burn clean, but the process for extracting it from the ground has contaminated more water resources and sickened more people in 5-10 years than the entire history of United States nuclear power generation.
We're tapped out on hydro - and that isn't completely safe either (Banqiao Dam anyone?)
Wind and solar are too variable for more than 10-20% penetration given the current energy storage technology we have. In Washington or Oregon, they have frequently had to shut down wind farms because the windiest times were also the rainiest, which meant that the hydro facilities were cranking at full capacity. Denmark exports a significant portion of its wind power and then buys it back from their nuclear/hydro-enabled neighbors, and many believe this is at a significant loss. (Denmark sells it when it's abundant and hence cheap, and buys it back when it's more expensive.)
Nuclear isn't perfect either - but of all of the power generation technologies out there, it has the cleanest and safest track record. Chernobyl and Fukushima are the only times in the history of nuclear power generation that more than a handful of members of the public have been exposed to anything but negligible hazards. (Note: I don't count incidents related to weapons detonation or production such as Kyshtm, since most countries are dismantling weapons instead of producing them.)

By their nature, the type of reactors used in the USA are not very suitable for producing weapons materials. They are difficult to refuel frequently, so the plutonium produced is contaminated with Pu-240 (bad for weapons). So reactors used for weapons production tend to be designed for frequent refueling to reduce the Pu-240 content. This generally results in various graphite-moderated designs. To my knowledge, the USA never used weapons reactors for civilian power generation. The UK may have (Magnox reactors), and the Soviets most assuredly did. (The graphite-moderated water-cooled reactor at Chernobyl was perfect for weapons production - it could even be refueled while operational.)
At this point, many countries are actually dismantling weapons and using the plutonium to fuel reactors (MOX fuel), or in the case of HEU weapons- diluting it to produce reactor LEU. See Megatons for Megawatts - many of our civilian reactors are fueled by dismantled Russian bombs.

Off course they will continue to im- and export electricity to neighbouring countries depending on the day. That's how the electricity market works. France's nuclear reactor for example tend to produce far to little electricity during the hottest part of the summer since they are mostly dependent on river water for cooling. Looking at the total energy consumption and production over the course of a year however Germany has a large electricity surplus. In 2009 this was 54.1 TWh (592.6 produced vs. 538.5 consumed [energy.eu])
As a matter of fact, the seven oldest nuclear plants can be shutdown without any problems [spiegel.de] immediately (which is what happened) since there is a significant production surplus. Even without the other nuclear power plants and all wind and solar power Germany still has enough production capacity to meet it's highest consumption moment so far. In practice that moment is always during the afternoon when you are guaranteed at least a quarter of installed solar power plus some of the wind power (since it's distributed across the fairly large country).
However, unlike the Ukraine and Georgia Germany has other sources of Gas (the Netherlands and Norway) and significant storage capacity.
The difference is that gas can be put into service (or out) much faster than nuclear. Itâ(TM)s a much better partner for intermittent renewables (Which is what Germany is going for to replace the nuclear power plants). And while existing nuclear electricity is indeed very cheap (because the massive investment cost have already been depreciated and because the producers donâ(TM)t have to pay for decommissioning). New nuclear power is a lot more expensive, doubly so after Fukushima. Building one on spec (that is, without public financial guarantees and/or investment)to be finished in 2018 is already more expensive [slashdot.org] than some of the feed in tariffs paid in Germany for solar now.

Of course! It is not like there are THOUSANDS of NUCLEAR WEAPONS ready to do actual damage at moments notice. No sir!! After all, nuclear power produces plutonium so efficiently that the highly inefficient US military decided to make their own plutonium pits instead for these weapons..
And of course plutonium cannot be used as a fuel because using that instead of virgin uranium makes bunnies cry.
proliferation point of view, with respect to the risk of nuclear terrorism
I say we go further. burn all physics books!, especially those ones that deal with particle and nuclear physics. No one needs to know about cross sections. It is the devils knowledge!!
On a more serious note, anyone that brings up proliferation as a significant problem is a little crazy. You know, there are these things like radiation detectors that can detect a few atoms of contamination. I think they would detect a nuclear reactor worth of fuel going missing... It is not easy to build a nuclear weapon even though conceptually it seems so. An effective plutonium device is very difficult to produce and a "dirty bomb" is the most useless type of a bomb and it is easy to clean up.
If you want to worry about proliferation, worry about chemical and biological agents because these happened and are likely to happen again.

Here's a nice list of attempting smuggling of nuclear stuff. Basically all after USSR fell apart. None of these were sourced from nuclear energy. They call came from nuclear weapons programs.

PS. This was mostly sarcasm, but since mdsolar is probably modding with 10 accounts, this will get -1 anyway ;)
And finally, nuclear energy from Uranium will not become exhausted for at least 1000 years. With fusion, nuclear will be permanent base load, unless we nuke ourselves over coal/oil/gas/food/water (take your pick) to kingdom come..

One also has to look at the high level nuclear waste. There isn't that much of it. On a pragmatic basis, toss it in a breeder reactor and keep using it until it turns to lead.
You underscored a problem. People go batshit when they hear the word "nuclear". Take a MRI for example. It used to be called NMRI. However, people heard the first word in that abbreviation and thought that their body's component atoms would wind up ripped apart like a bad Star Trek transporter malfunction if they were scanned by

Big Oil knows its stuff, and the fear campaign is working, and has worked since even before 3MI. The guys know that nuclear power would kill Big Oil.
Why? Reactions that are (as of now) energy expensive could be done on massive scales. Desalinate water, pull CO2 from the air, combine the two in a number of reactions, and one can get ethanol. Combine a reactor and a thermal depolymerization plant (which essentially "boils" plastic to short chain carbon atoms), and gasoline would be ready to be used from t

I live above the Marcellus Shale gas formation.
Given the rampant groundwater and stream contamination resulting from hydrofracturing operations south of me in Pennsylvania - I'll take a brand-new modern nuke plant in my area over the commencement of gas drilling operations without any hesitation.

This is one of the key reasons I am a much bigger supporter of the nuclear industry than the gas industry. The nuclear industry admits to their mistakes and constantly strives to improve safety - look at the vast improvements in safety design from BWR to ABWR to ESBWR even before the first BWR accident in history. When an accident occurs, changes are made to prevent it from happening again.
The gas industry, on the other hand, simply says "we are safe". They won't tell you what is within the fr
