Will that take a coal fired plant off-line?
Or will the old steamer respond to fluctuations in demand while the nuke operates in a steady state?
 
"The reactor achieved first criticality - its first sustained nuclear fission reaction - at 2:16 am EDT yesterday and is now generating heat under its own power. TVA said that the unit was operating in a stable condition at low power levels that will slowly be increased over the coming weeks as it moves towards commercial operation."

This is great news. The US needs to replace aging coal fired plants built in the 60s and 70s which are currently operating well past their intended life spans.

How many more are under construction?
 
People do not realize how much carbon these nuke's prevent from going into the atmosphere. They just need to be operated safely. Easier said than done when we do not replace the old plants with new plants. The best thing that can be done for safety is to replace the older plants with new plants.

The greenies do not want a solution, they are in this for the "struggle.". Building nukes based on 21th century tech would be a solution.
 
The biggest problem with nukes is their waste. Until we start producing less dangerous waste or start reprocessing it they should not be expanded. They are not even economical to run currently.

Most nukes in the USA run at about 95% capacity through out the year.
 
The up-stream coal supply includes mining and transportation ghg and other pollution factors.
Down-stream pollution such as acid rain and smoke upset greenies the most.
They make more noise than a riled-up mule in a tin barn.

?

Nukes have a cost of around 6.5 cents per KWh to run due to their output (at least that's the case for the Canadian ones). Which is a heck of a lot better than wind or solar, which are in the mid teens (14-18 cents).

Here is how they are dealing with the waste in France BTW:

http://www.areva.com/EN/operations-1092/areva-la-hague-recycling-used-fuel.html

Quote:
Entering into service in 1966, the AREVA site in La Hague, the leading industrial center of its type in the world, processes nuclear used fuel for subsequent recycling - fuel which has been replaced in nuclear power plants.

Once discharged from the reactor, the used fuel contains:

96% recyclable material: 95% uranium and 1% plutonium, which will be reused to produce electricity.
Just 4% waste (fission products and minor actinides).
Processing, the first step in recycling, is a high quality service. Throughout the process, the nuclear materials in the used fuel remain the property of AREVA's customers.

AREVA La Hague receives used fuel sent by french and foreign electricity companies.

In accordance with French law:

The waste taken from used fuel from foreign electricity companies are returned to their country of origin after processing.
French waste is temporarily stored onsite pending a permanent storage facility.
The recycling of recovered materials (uranium and plutonium) enables:

Savings of up to 25% in natural uranium needs,
Reductions in the volume and toxicity of final waste, to a large extent, through processing and conditioning designed to suit each type of waste.

That's not true in Illinois. The cost is closer to $0.18 per kwh. Windfarms here sell their power into the market for the wholesale rate of $.037, the same market that nukes have to compete in.

Is that rate (for the wind farms) subsidized?

And interesting article on the cost of wind (and it also confirms your nukes are more expensive than ours to operate but that's an aside at this point):

http://www.forbes.com/sites/christopherh...r/#1eb5145012ef

Which pegs a total cost of around 15 cents per KWh.

As for Ontario (my perspective here):
http://www.windontario.ca/

Quote:

Ontario pays 11-13.5 cents per kWh for wind power.
The average price in the U.S. is 7 cents.
The average price for Ontario nuclear, water and gas is 7 cents.


We also get the majority of our power from the nukes though (and have a very large amount of generating capacity installed):
https://www.cns-snc.ca/media/ontarioelectricity/ontarioelectricity.html

And from the horse's mouth on the cost:
http://www.brucepower.com/affordable-electricity-stable-prices/

Quote:
The electricity generated from Bruce Power nuclear is among the lowest cost generation in the province and provides price stability for Ontario families and businesses.

Like most generators in Ontario, Bruce Power’s price for output is controlled by the province through a contract with the Ontario Power Authority (OPA). In 2013, the average price paid for output from the Bruce Power site was 6.2 cents per kilowatt hour (Kwh) – a very low cost supply source for the province.
The price paid for Bruce Power nuclear includes $7 billion of private investment over the last decade into publicly-owned assets, which includes the refurbished capacity from Units 1 and 2 and a wide range of other investments to extend and optimize the output from the site.

The cost of electricity is often a misunderstood issue, as there is confusion on the role of the Hourly Ontario Energy Price (HOEP) and the Global Adjustment Mechanism (GAM). The figure below illustrates the percentage of supply from each energy source in 2013 and their contribution to the GAM.

As the figure illustrates, the lower-cost sources of electricity, such as nuclear and hydro, contribute to GAM on a lower percentage than the volume of electricity they produce, due to the fact they provide large volumes of clean electricity, keeping costs low for Ontario ratepayers.

There is also the perception the large capital requirements for nuclear projects equate to a high price of power for consumers – this is not the case. Since nuclear plants generate a large volume of electricity, with a high degree of reliability, the capital requirements of the facility are spread over significant amounts of generation, meaning the cost to ratepayers is affordable. In the case of Bruce Power, the price paid for electricity covers all costs, including decommissioning of the facility when it reaches its end of life, the management of low-, medium- and high-level waste, and capital investments in the facility.
 
The going wholesale rate in Illinois is $.037 per kWh. Windfarms get an income tax credit of $.022 per kWh. Whether you consider an income tax credit a subsidy is different that a direct payout subsidy.

The biggest driver in the lower cost of electricity is the upsurge in the use of natural gas for the primary fuel.

See, we have the opposite trend happening. Wind and Solar are both heavily subsidized, which we then see reflected in the rates we are billed. Did you take a look at the Forbes article?

It states:

Quote:
According to the federal Energy Information Administration, the “levelized cost” of new wind power (including capital and operating costs) is 8.2 cents per kWh. Advanced clean-coal plants cost about 11 cents per kWh, the same as nuclear. But advanced natural gas-burning plants come in at just 6.3 cents per kWh.

But it could be getting a lot worse for wind. A fascinating new report by George Taylor and Tom Tanton at the American Tradition Institute called “The Hidden Costs of Wind Electricity” asserts that the cost of wind power is significantly understated by the EIA’s numbers. In fact, says Taylor, generating electricity from wind costs triple what it does from natural gas.


Which would indicate that you guys are paying less for wind than it takes to operate (using the EIA numbers) and those numbers don't factor in the requisite backup generation capacity or transmission interconnect construction and the like (which may or may not be relevant depending on how you view it).

My takeaway is that even using the EIA numbers, wind in the US is still more expensive than nukes in Canada. And I would expect wind in Canada to cost more just like everything else does up here

I read the article. It is propaganda. The tax credit runs out in 10 years here in the US for new windfarms. Coal is dead and so is nuclear if they don't get a way to fix the waste problem.

The problem with those numbers is they do not include all the cost from cradle to grave. Coal is finding out that the ash they have stored and need to get rid of will cost 100s 0f millions and the same for the nuclear plants. The two in Illinois that are getting shut down, Clinton and Quad Cities and lost $100M a year each for the last 8 years. This is the second time Clinton has been shut down due to unprofitably since it was built in 1987. It never has turned a profit.

And one needs to ask where would the nuclear industry be if it were not for Federal subsidies and outright paid for development before raising the subsidy question? You also need to be aware that in the US the main reason for the proliferation of nuclear plants was for a source of plutonium used in nuclear bombs. This really is no longer needed.
 
Here's what the nuke plants have to face in my area.

Efficiency, gas plants push PJM capacity auction prices below expectations

http://www.utilitydive.com/news/efficien...tations/419806/


PJM Interconnection's 2019/2020 capacity auction netted 167,306 MW, the grid operator announced yesterday, but at "competitive prices" that surprised analysts and could force some less-competitive power plants to close.

The clearing price was $100/MW-day for the majority of the region, a sharp decline from $164.77/MWd generators saw in the last auction. The highest prices came in Commonwealth Edison's service area, at more than $200/MWd, but that was also down from $215/MWd the year before.

The grid operator said energy efficiency was in part responsible for the lower prices, in addition to the impact of low natural gas prices. About 1,500 MW of efficiency resources cleared the auction, with 1,058 MW clearing as capacity performance, a designation that carries stricter delivery standards.
 
One of the problems with the Forbes article is the cost and how they are determined. In Illinois the actual producer does not directly sell the electricity. While Exelon (owner of the nukes) does produce power and sells it in the northern part of the state, they first sell it wholesale then buy it back again from Ameren which is the transmitter of the power.

My electrical coop does not produce any power. They buy it from the generator who is also a national coop power provider.

Here is my electrical use for 2015, notice how the cost are broke down.

The 2nd part is (the extra costs) but the initial figure is not propaganda, it is from a reputable source (the 8.x cents). Did you read the link to how France is reprocessing their fuel? There's another exhaustive article that I've posted in the past that covers not only reprocessing, but also additional reactor technologies that allow for further use of the fuel that results in a final product that is only a tiny bit radioactive and subsequently has very lax storage requirements.

Which costs? mine or yours? Our nuke plant storage is on-site and considered part of the operating cost of the plant. We have no coal in this province at this point, we are all nukes, hydro, GT's and a bit of wind and solar.

That's a great point, and was never part of the development program for our plants. Nuclear, as shown both here and in France, can be extremely cost effective when your goal isn't weapons-grade Plutonium. The CANDU's have a lot of rather neat features (like on-line individual fuel bundle swapping via robot, no cooling towers....etc) that set them apart from the American counterparts.

Yes, the gas plants have the lowest costs in the states, and that's supported by the material I've posted as well. Your nukes are almost twice as expensive to run, so that doesn't make sense. Your GT's cost about the same as our nukes.
