Hugh Pickens writes "With backing from the White House and congressional leaders, and subsidies like the $500 million in risk insurance from the Department of Energy, the nuclear industry is experiencing a revival in the US. Scientific American reports that this week NRG Energy filed an application for the first new nuclear power plant in the US in thirty years to build two advanced boiling water reactors (ABWR) at its South Texas nuclear power plant site doubling the 2700 megawatts presently generated at the facility. The ABWR, based on technology already operating in Japan, works by using the heat generated by the controlled splitting of uranium atoms in fuel rods to directly boil water into steam to drive turbines producing electricity. Improvements over previous designs include removing water circulation pipes that could rupture and accidentally drain water from the reactor, exposing the fuel rods to a potential meltdown, and fewer pumps to move the water through the system. NRG projects it will spend $6 billion constructing the two new reactors and hopes to have the first unit online by 2014."

Besides, reprocessing spent fuel (which is not currently done in the US) increases the energy output of a given amount of uranium 60 times [wikipedia.org]. In addition, reprocessing removes (burns) various troublesome byproducts which would otherwise require long-tem storage.

To simplify things greatly - Many of the byproducts (especially the final one, lead) poison nuclear reactions and make it so that if the fuel contains more than a certain amount of those byproducts, it is no longer capable of sustaining fission.
Unfortunately, most current reactor designs (including new ones) are quite inefficient in this regard. More efficient reactors get shot down for various reasons. For example, the IFR research reactor was shut down by politicians because of proliferation concerns - even though the reactor was less of a proliferation threat than even normal civilian PWRs. (They saw "breeder" and instantly thought "nuclear weapons" even though the IFR waste material would have been useless for producing weapons-grade fissiles.)
The IFR had some great advantages - It was far more efficient in terms of extracting energy from uranium, and it could burn basically any actinide (including those normally considered "unburnable waste" from other reactors). Compared to PWRs, its waste was MUCH more radioactive (bad), but significantly shorter lived (very good) - Something like 50-100 years half life for the longest-lived byproducts, as opposed to thousands of years for the waste actinides from PWRs.

I find it a little bit amusing and a little bit sad whenever people rail about "We only have X amount of resource Y left!". It's idiotic. Natural resources don't work that way, as though it's some sort of canteen that we're drinking out of, that suddenly we'll take the last sip from, and that's it. In the real world, it's almost always "We have X amount of resource Y left recoverable at current prices with current technology." As prices rise or technology improves, what's recoverable increases. Think of it this way: your average granite contains 10-20 ppm uranium, and is the most common mineral in the lithosphere. I'm not sure of the percent; let's say half of the lithosphere is granite (other igneous minerals will also tend to contain similar amounts of uranium). The mass of the lithosphere is 1.365e23kg, so about 70,000,000,000,000,000,000 (70 quintillion) metric tonnes of uranium in the lithosphere.
Of course, almost all of that is not even close to economically recoverable. But it's there. We don't "run out" of minerals; we just run out of things that can be extracted at current prices. But then another issue comes up: as current prices rise, what becomes economically recoverable rises as well. Not just linearly -- generally exponentially. Ideal, cheaply mineable deposits of minerals tend to be rare. Poorer deposits, however, are often an order of magnitude more common. Poorer still, add another order of magnitude, and so on. But it's not only rising prices that make things economical; it's also advancing technology. We continued building oil rigs in the 80s and 90s when gas prices were down -- yet, earlier in the century, the concept of building rigs during a period of low prices would have been laughable. We advanced the technology to the point where it was no longer uneconomical to use. The same thing has been happening with bitumen extraction in the present-day; it gets cheaper and cheaper as the technology improves.

Considering that the majority of all CO2, particulate, soot and trace elements like mercury are spewed into the atmosphere by coal fired plants, I don't understand why the environmentalists aren't clamoring for more nuke plants. I'm guessing that the antiwar/antinuclear weapon factions didn't make the distinction between bombs and power plants.

Re:Boom (Score:5, Interesting)
To achieve this goal, instead of being water-moderated (like in all civilian US reactors), it was graphite-moderated.
This meant that if the water boiled off, it would actually increase output power (among other things). U.S. civilian PWRs lose the ability to continue the reaction if the coolant disappears because it is also the moderator.
In the case of Chernobyl, the graphite moderator had other problems - When the initial steam explosion occurred, the lid on the reactor pressure vessel was blown off, and exposed the graphite to air. Superheated radioactive flammable material + oxygen = BAD.
Chernobyl could not have happened in any U.S. reactor, both due to differences in safety policies and in fundamental reactor design. The worst accident in U.S. history (TMI) released less radioactive material into the environment than some coal-fired power plants release in just one day of operation due to trace amounts of uranium in the coal they burn. (There's one coal plant in Utah that is especially bad I believe.)
Given the choice of living 5 miles from a nuclear PWR, and 5 miles from a coal plant - I'll take the PWR!
Re:Boom (Score:5, Informative)
No nuclear power plant can blow up in a nuclear explosion. First, the enrichment level of nuclear fuel for power plants is far too low to be able to cause an explosion, and second, even those reactors that use highöy enriched fuels have fuel elements in configurations that are unsuitable to create explosions. Remember that atomic bombs both need a very high enrichment level and a very precise shape to be able to explode. That's why it is difficult to produce atomic bombs.

Another location issue pertains specifically to Texas. Texas wind power has been growing very rapidly and may easily meet anticipated demand. Wind costs about $1.30/Watt to build while the nuclear plant, at this early phase, is anticipated to cost $2.20/Watt without modifications that come up in the licensing process or construction delays that genrally plague large projects.
South Texas may not be the best place to test the waters on new nuclear generation.

Maybe one day we will have thermonuclear power plants, the nuclear reactors will be obsolete, and we will have abundant energy. I dunno. Right now, however, there is a shortage of energy. We rely too much on natural gas and petroleum. The exporters of those feel their power and twist the arms of the importers. The money made from gas and oil are insane and they are the foundation of too many of the world's tyrants and lunatics-in-power. Cut their revenue streams and they will suffocate.
It seems that making abundant electricity can alleviate that problem at least as far as natural gas is concerned, so we can get rid of the natural gas racketeers (mainly Russia). If we go to hydrogen economy we can liberate ourselves from the petroleum racketeers as well. To have hydrogen-based economy we need a lot of energy. People get excited by the progress in fuel cell technology but rarely ask themselves how hydrogen is to be produced in gigantic quantities.
True, there are risks in nuclear energy production that can't just vanish. But, dammit, nuclear energy has no alternative for the moment.

If it's not a fast breeder reactor, it's not a solution to the energy problem.
U235 would run out within the next 60 years, IIRC, if we got all of our power from traditional nuclear powerplants like this one!
However, the world has tons of U238, so breeders could provide power for a long time. And if you made the changes necessary to run the breeders on Thorium instead of U238 (Thorium is even more abundant), then you coul provide power nearly indefinitely.
Breeders also solve the waste problem: The reason radioactive waste is so dangerous is that it still has tons of energy in it; the decay is the slow release of that energy. Since breeders extract so much more energy from fuel, their wastes have much shorter half-lives, and decay to the levels of naturally-occurring ores within a few hundred years -- which isn't great, but (1) sure beats the millennia we're talking about with our current wastes, and (2) seems to be a timescale society can handle.
We need breeders. Pebble-beds are wasteful; they (1) don't breed, and (2) generate a lot of pebble-coating waste. Anything but breeder reactors, and solar/wind/geothermal/hydro, is a waste of time. Breeder reactors are the only technology we currently have that can solve the energy problem. We should be building breeders.

America after World War Two was magnanimous; we had freed a billion people, almost completely for free (the Brits had a lend-lease thing going on) then we started pumping in millions for all the cities we'd just blown up: we realize, at the state level, that we need the other nations...but we don't need to conquer the other nations.
America has never said it wants to attack, change the government and own another nation; we don't want more territory- we just want wars there to stop. It's maddening when we take part in a distant war (think Bosnia) where we bombed the Christians and worked for the Muslims, and then come home. But we're not about expansion-for-expansion's sake, many/most of the UN members cannot make such a claim.
The president of Iran for example has spoken many times of using a nuke to wipe Israel off the planet (in direct violation of UN law) so many times, we're pretty sure he means it. So...what do you think he'd do if he had one? And after that job was done, he'd bully the neighbors.
We used the atomics at a very, very early stage; we were in the largest war, ever, working against time with the Germans who were close to getting it first. But notice: in 60 years or so, we've never used it in anger. As a nation whose leaders are accountable to the people, it makes it very hard for a madman to rise to the ranks and do the deed. (And notice Regan didn't; he was trying to scare the Russians, and the best way to do that is to tell the Liberals something scary, since the friend-of-my-enemy is a Liberal. The Kremlin was behind the No Nukes Movement...I know what I'm talking about, here.)
It's just so surreal, though; knowing the good we've done, the 40,000 men who died to clear France for example, the play-by-the-rules military that we have, and there's a world of bloggers trying to convince us *WE* are the enemy. George Soros is definately getting his money's worth. I just hope there are History books that can be written, to store the history of the greatest propoganda posed by man.

The standard delusional fantasy is that a pound of Pu 239 can cause 8 billion cancer deaths, plus or minus. Which begs the question, what are we all doing here? What with the hundreds of pounds of plutonium atomized into the atmosphere in the 40's & 50's.
Another thing is, I wonder if you could concentrate the "badness" of CO2 into a small enough volume that would enable you to store it indefinitely instead of releasing it into the biosphere, how nasty would that substance be? Pretty nasty I would think. But if you could, would you? I bet you would. So in fact what the Munch-style disaster fantasists consider to be nuke's Achilles tendon is actually something you would like to do with other technologies, if only you could. Funny, huh?
And finally with regard to the BWR design...once again it's the American approach of using partially enriched uranium. Which goes way back to the original decision to use that fuel strategy because you can make smaller cheaper reactors and what the hey, the U.S. has all those enrichment facilities sitting around that were built for...other things. Too bad it would be impossible to buy Candus because, well a) no enrichment facilities needed, they take natural U (if Iran really just wants to generate power they could do it without all those scary centrifuge thingies) and b) its a clever reactor structure that consists, and I'm not kidding here, of a series of tubes instead of one gigantic bucket, which makes it structurally redundant and intrinsically failsafe (did you know Canada had their own TMI event where the main reactor structure cracked and the big result was, radioactive water on the floor?) and c) you can shove fuel in one side and take it out the other while it's running and you never have down time for refueling.
But that's a pipe dream. What the US will get is unfortunately, glorified aircraft-carrier power plants, because, you know, might as well monetize some military technology that's just sitting around. More profitable that way, don't you know.
