First New Nuclear Reactor In a Decade On Track
dusty writes "Plans to bring online the first new US nuclear plant since 1995 are on track, on time, and on budget
according to the Tennessee Valley Authority. TVA had one major accident with a coal ash spill of late, and one minor one. The agency has plans and workers in place to have Unit 2 at Watts Bar, near Knoxville, online by 2012. Currently over 1,800 workers are doing construction at the plant. Watts Bar #1 is the only new nuclear reactor added to the grid in the last 25 years. From the article: 'TVA estimates the Watts Bar Unit 2 reactor every year will avoid the emission of about 60 million metric tons of greenhouse emissions linked with global warming. ... TVA began construction of Watts Bar in 1973, but work was suspended in 1988 when TVA's growth in power sales declined. After mothballing the unit for 19 years, TVA's board decided in 2007 to finish the reactor because it is projected to provide cheaper, no carbon-emitting power compared with the existing coal plants or purchased power it may help replace.'"
Common sense prevails. Nuclear is the best option we have right now for clean, cheap, reliable energy.
1). Inhabitable? Don't you mean uninhabitable?
2). It doesn't "just take one". We've suffered more than one nuclear reactor failure in this country without experiencing mass-contamination events along the lines of Chernobyl. Three Mile Island wasn't the only one.
I hate to feed the troll, but:
one nuclear accident could render a majority of the US inhabitable. Presumably you meant "uninhabitable", but you'd still be wrong.
In the 1940s-1950s, the US detonated numerous nuclear weapons above ground in Nevada and New Mexico, releasing a hell of a lot more radioactive material than Chernobyl -- and Chernobyl-type disasters cannot happen with US power reactors (totally different reactor design). This hardly rendered even a significant fraction, let alone "a majority" of the US uninhabitable.

And of course now that we have such a "green"-friendly president we are now going to build a few new nuclear reactors!
[Yes, that was sarcasm]. It is unfortunate that our current president and Congressional leadership are so anti-nuclear. You'd think they all still believe the lies and exaggerations of 1960s and 1970s environmentalists. We need to build many more nuclear plants, recycle spent nuclear fuel, and figure out and build better electric cars. That should help out our economy and environment.
Your car has four wheels and an internal combustion engine, traits shared by the 1907 Holsman Model 3. Have you stopped to consider the intense danger this poses to you?
But wait: The Holsman was built in a time before ABS, crumple zones, air bags, or even seatbelts. One might presume your 2003 Nissan Altima to be a little safer.
Chernobyl was a nuclear plant built with all the safety precautions of early automobiles. Comparing it with modern TVA-built plants is just as valid as the above Slashdot Car Analogy.

Correct me if I'm wrong, but doesn't the US have naval submarines that are powered by nuclear reactors. And aren't those subs often docked near populated ports, San Diego for example. Thus, we have already accepted the risk of having nuclear power in populated areas, so it seems odd to be afraid of adding a few civilian nuclear reactors that are not in highly populated areas.
Don't be silly. Our current president is much smarter than that.
He understands that opposing nuclear technology is much more valuable to him politically than using the technology to reduce our carbon emissions in a significant fashion. And maintaining power is more important than the environment.

Agreed. It's mostly irrational fear.
I could see where one would trust a reactor that was built FOR the military and operated BY highly trained military personnel. Too many civilian projects and products get hit by lowest-bidder disasters.
1.5 years into a 5-year project, the project is on-time and under-budget?
Quite conceivable, especially since the main contractors (Bechtel, Siemens, Westinghouse) are not operating on cost-plus contracts. But this early into a project, it is a bit premature to assume that it'll continue to be under-budget and on-time. But who knows, maybe it will be. The reputation of the contractors (especially Bechtel, as primary contractor for most of the work) depends on it. This is especially important given that the market for construction of nuclear facilities in the US has the potential to, um, explode over the next decade or two.
Keep in mind that the biggest boondoggle of over-budget and past-due construction (the Big Dig in Boston) was under budget and on time for the first several years of construction.

I recently read about Chernobyl on wikipedia. That entire episode was apparently ... well, incredibly stupid and mismanaged. It was more of a "Titanic" incident than anything else I can think of in history. (The "nothing will go wrong" mentality that leads to some really, really stupid actions)
I'm kind of neutral about the whole subject. Neat tech, but trusting corporations is not in my nature.
Also, when compared to wind and solar, Nuclear is the one power source that allow corporations to retain control of power generation.
But balancing that is the fact that it's a pretty continuous source of energy...
What I'd really like to understand (I always ask this and I've never gotten an answer) is why some people are so for it. They aren't going to make money off it, overall it will not save them money (Even those of us who live exclusively off dams don't have THAT much of a money savings)...
I can understand people being really against it. Fear of the unknown, lack of understanding, history (quite a few people have died in the past)
I can also understanding someone being somewhat for it (I'd be tempted to vote for one in my city, although the last one here was a complete cluster-fsck) but where does one get the motivation for the positive passion that this topic so often seems to create?
I think it's great to see new nuclear power coming online, but it's too bad this is simply the completion of a project begun in the 1970's. There hasn't been enough work done in the US to advance the design of nuclear power stations in the last few decades. I wonder how much more efficiently these stations could be built and run today if we had been focused on the problem all this time.
The article doesn't really provide enough information to support the conclusion. All
Summary: Radioactive elements in coal and fly ash should not be sources of alarm. The vast majority of coal and the majority of fly ash are not significantly enriched in radioactive elements, or in associated radioactivity, compared to common soils or rocks.
Right, but that doesn't help because it discounts the quantity of coal, and the fact that it is being burned and released into the atmosphere. It didn't answer at all the amount of radiation released in total, only the density of the radiation. The question is: Does a coal plant release more or less radiation than a nuclear plant with equivalent output?
About Coal Creek Station: In 1993, the Nation consumed more than 2 million tons of coal per day.
And the article you linked to says:
concentrations of uranium fall in the range from slightly below 1 to 4 parts per million (ppm)
But don't know what 2 million tons x 1 part per million means.... soo... Aha!
Coal ash is more radioactive than nuclear waste
The editor clarifies, at the end of the article:
*Editor's Note (posted 12/30/08): In response to some concerns raised by readers, a change has been made to this story. The sentence marked with an asterisk was changed from "In fact, fly ashâ"a by-product from burning coal for powerâ"and other coal waste contains up to 100 times more radiation than nuclear waste" to "In fact, the fly ash emitted by a power plantâ"a by-product from burning coal for electricityâ"carries into the surrounding environment 100 times more radiation than a nuclear power plant producing the same amount of energy." Our source for this statistic is Dana Christensen, an associate lab director for energy and engineering at Oak Ridge National Laboratory as well as 1978 paper in Science authored by J.P. McBride and colleagues, also of ORNL.
As a general clarification, ounce for ounce, coal ash released from a power plant delivers more radiation than nuclear waste shielded via water or dry cask storage.
And the military isn't?

No one answers the question: Where are you going to put the waste? You can't recycle or reprocess everything and whats left is mind bogglingly bad.
The reason is, there is no answer for a 250,000 year problem like that. Even if you find a 'solution' to keep it out of the easy to parts of the world we use you still have left future generations a crap load of trouble in addition to what every they will have to deal with.
Thanks mom.
The title is pretty misleading, as it omits "US." One might also look outside of the US borders for some examples of how new nuclear power plants are coming along -- or aren't.
>Environmentalist wackos want us to turn off electricity and live in paper hats,
Did you mean "huts"? Although living in a giant paper hat might be fun, at least until it rained.
Anyway, who are these nuts? Where are they? I have read about them, but I have not seen
any evidence that these creatures still exist in the wild. I am convinced they went extinct
in the 60s or 70s. Certainly I have not found any in the environmentalist communities I
frequent.

"As a general clarification, ounce for ounce, coal ash released from a power plant delivers more radiation than nuclear waste shielded via water or dry cask storage."
That's a fairly big qualification, though, isn't it? Raw coal ash vs *shielded* nuclear waste?
I don't think many environmental protestors are claiming that nuclear waste, if shielded, emits radiation. The worries are about whether the shielding actually survives and doesn't break down over years, leach into groundwater, etc.
