How Much Nuclear Waste Does Your State Hold?

One of the biggest critiques of nuclear energy is that it produces radioactive waste in the form of used nuclear fuel, or UNF. While the amounts are relatively small -- just 20 metric tons per power plant annually -- they remain radioactive for periods of time that are difficult for humans to comprehend. The waste adds up across the 100 nuclear reactors currently in operation across the United States. At last count, the country's atomic fleet had produced approximately 69,720 metric tons of UNF over the past four decades.

More than 50 sites across the country are licensed for dry cask storage of spent nuclear fuel. Source:  

Where does it all go? Power plants first store waste on-site in steel-lined concrete pools. After maxing out capacity, however, waste is stored in large dry casks similar to the ones pictured above. They may look intimidating, but there has never been a radiation leak since dry storage techniques were implemented in 1986.

Phew! No worries. But really, do you live in a state that hoards radioactive waste?

State-by-state breakdown
You may think that just because your state doesn't have a nuclear power station it doesn't have any nuclear waste. Of course, you may be wrong. While 31 states have an operating reactor, 38 contain at least some nuclear waste. That means seven states have really persuasive leaders! Here's how it plays out for each state (numbers in metric tons):

If you live in one of the 12 white-colored states on the map above, you're in the clear. For the rest of us, living within the same borders as spent fuel is just reality. Obviously, the states with more generating capacity will generate and therefore store more waste. The top 10 states hold 64% of all UNF in the United States.

South Carolina


New York


North Carolina

*California's total was updated as of Dec. 31, 2012 and is higher than what appears on the map. Sorry, California.

Who are the biggest culprits? Exelon (NYSE: EXC  ) is responsible for the majority of the waste currently being held in Illinois and Pennsylvania (that comes naturally with 19,000 MW of annual nuclear capacity). It has managed to persuade Idaho to store used fuel from its Three Mile Island reactors, however. The reactors and storage facility are more than 2,400 miles away. Sneaky, sneaky.

Duke Energy (NYSE: DUK  ) feeds the nuclear-heavy grids of North Carolina, South Carolina, and Florida. Not surprisingly, it ranks second in the nation with 11,350 MW of nuclear capacity. Rounding out the top three is Southern (NYSE: SO  ) with 8,280 MW of annual capacity. The company maintains three facilities in Georgia and Alabama, although it doesn't necessarily contribute the most spent fuel in either state. Either way, the figures in the preceding table make plenty of sense when you look at where the largest atomic powerhouses produce their power.

Is it really all bad news?
The good news that gets relatively little attention is that each power generator pays into the national Nuclear Waste Fund with every fuel purchase. If every nuclear power plant were decommissioned tomorrow, the industry would need approximately $31.9 billion. Luckily, more than $22.5 billion has already been funded -- the remainder will be collected over the next 20 years.

That still doesn't solve the problem of the waste itself. Just as the industry transitioned from pool to dry cask storage out of necessity, I believe it will eventually make the leap to full fuel recycling technology. Partners Hitachi and General Electric (NYSE: GE  ) have pioneered the PRISM reactor -- a generation 4 reactor (all reactors in use today are generation 3 or lower) -- which is powered by spent nuclear fuel. Perhaps the pair will receive funding directly from the Nuclear Waste Fund for their technology in the next decade or two.

Still skeptical? Before you build a bunker in your backyard, stop and take a deep breath. You shouldn't feel any differently now than you did before you opened this article. There is certainly a UNF storage problem forming on the horizon, but to date there have been zero leaks concerning energy-related waste with current technology. Admittedly, only novel reactor designs, such as PRISM, can truly make a dent in the pile of nuclear waste your state is hoarding. I'm optimistic that it is only a matter of time before one is built. Are you?

But your map shows no nuclear waste storage in NM. Was the WIPP site relocated to another state in the last 15 years?

Spent nuclear fuel is bio-toxic for 100,000 years, 20 times the length of recorded human history. The number is so large it is incomprehensible, so we simply put it out of our minds and allow this nightmare to go on. We have produced enough deadly waste to kill every animal on the planet, 100 times over 50,000 years from now. There is theoretical technology (nuclear fusion) that could detoxify this mess- we should focus on that!

    It's to Fool Maxx Chatzko's credit that he acknowledges ...

    "to date there have been zero leaks concerning energy-related waste with current technology".

    To be more precise, there has been zero leakage of used *nuclear* fuel and zero public harm from it. Leakage of used fossil fuel is the rule rather than the exception, and when the used fossil fuel is in the form of carbon monoxide, it routinely kills.

    Some of the comments refer to government, or an unspecified "they", as having lied about this. That doesn't work the way they think it does. Royalties and excise taxes on fossil fuels mean that with every carbon monoxide death comes a hefty chunk of government income.

    Therefore when governments lie about nuclear power, their lies are in the direction of exaggerating hazards, or indeed suggesting they exist when they don't.

    The commentator who said "the public has no idea just how irresponsible it is to the population and to humanity to use nuclear fission to create power" is, again, right -- but not the way he thinks he is. If the public ever *did* get such an idea, a lot of antinuclear activists might soon be hanging from lampposts.

    Just some input here, they didn't "lie". Nuclear fuel stops being economically fissable after approximately 18 months, however that does not mean it isn't still radioactive. The spent fuel, as it is called, is still "hot" and needs to "cool" before it is able to be moved off site. This is the case with all nuclear fuel. Think of it this way you can't just grab ashes after a fire goes out, you need to let it cool first.

    Dry cask storage is safe only for a tiny fraction of the time of the material being dangerous. The full cost of safely storing UNF becomes astronomically high when you consider that it is highly dangerous for many 1000s of years.

    Our current generation is probably at the peak of human mankind causing long-term harm to our planet. Better solutions are needed like wind, solar. Thorium reactors and hopefully some day fusion reactors.

    One such option that is often ignored is geothermal energy, produced from both conventional hydrothermal and Enhanced (or engineered) Geothermal Systems ...

    For a quick view :

    It's clean, available 24 hours a day, 365 days a year, an almost unlimited amount of energy, can be tapped almost anywhere, emissions are low, is easily integrated into communities with almost no visual impact, does not require storage, transportation, or combustion of fuels,has long-term sustainability, the initial cost for the field and power plant is LOW around $3500 per installed kW in the U.S, has low operating and maintenance costs range from $0.01 to $0.03 per kWh, is ideal to provide base load, the energy produced cost $0.05 per kWh. . . .


    It will only happen though if industry, people,and governments, that is us Fools get on board and push this blindingly obvious technology to the forefront. . .

    Just think if Japan (On the ring of fire.) had gone

    down the geothermal route instead of nuclear, there would be no meltdown in Fukushima nuclear plants, so just say. . .

    I was not specific enough in my comment above. The major nuclear waste product from spent nuclear fuel rods has a half life of 12,500 years. Other isotopes are shorter or much longer. Try to imagine the claim that anyone will keep this waste "safe", for the 6 or 8 half-lives required for it to decay (80-96,000 years). The USA will be a forgotten memory when even one half life has passed! The first job is to end nuclear fission ASAP, the second is to find a way (such as nuclear fusion) to detoxify the isotopes. In less than 70 years, our nuclear industry has produced enough weapons to destroy humanity, and enough waste that humanity could be destroyed any time in the next 100,000 years!

    Just having UNF on this list means very little. Fuel for nuclear power plants is low-enriched nuclear fuel. While you don't want UNF laying around in the open, I would be much more concerned about waste left over from the weapons programs when we were producing enriched plutonium.

    This list shows that NM, NV and WA shouldn't be concerned about UNF, but nothing about nuclear waste at the Nevada Test Site. That's why the state and DOE fought to close the Yucca Mountain Site, they already have all the waste from underground nuclear testing, about 1200 of them. All the waste is sealed underground for however long it takes plutonium to decay, only several hundred thousand years. Washington state has the Hanford Site right next to the Columbia River and South Carolina has the Savannah River Site. People have mentioned the WIPP site, but that transuranic waste, not as bad as plutonium waste.

    Just having *either* used nuclear fuel *or* radioactivity due to bomb-making means very little on a radioactive planet such as ours.

    Plutonium is hazardous due to its radioactivity, and in the time when nuclear waste is really dangerous, it is so because of other, much hotter materials than plutonium. The arithmetic for making these comparisons is quite difficult, so much so that even when computer programs such as ORIGEN2 make it easy, it's still difficult.

    However, "Spent Fuel Explorer", a front end for presenting some ORIGEN2 results, is free on the web, and makes it a lot easier again.

    With its "decay heat" setting we can learn that 1.1 days after shutdown, nuclear fuel that has been working at 39 thermal megawatts per tonne is still producing 0.1925 megawatts per tonne.

    There is a timeline with a slider you can drag with your mouse, and a pie chart showing how the heat production is divided between isotopes. Slide it far enough to the right and the red pie slices that represent plutonium grow to half of the total. This happens at 1220 years, and the heat due to plutonium is 0.00002676 megawatts per tonne.

    Because its half-lives are so long, this is pretty much the same heat it was producing at 1.1 days. So at that time, the fraction of the rays that are due to it is rather small: 0.00002676/0.1925.

    If there were genuine, informed concern over plutonium, the Greenpeace associate photographed with a nuclear icebreaker at might be expected to be about 1925/0.2676 times more concerned, 7200 times more concerned, about the other radioactivity in that boat's two reactor cores.

    I notice Maxx Chatsko's fact 24 in "30 Facts That Demystify Nuclear Energy" is a uranium-to-natural-gas price ratio of 0.51. This must be on some apples-to-rice-grains basis of comparison.

    The most sensible basis is equal energy, and on that basis, with natural gas at $4 per MMBTU and uranium at $0.155 per MMBTU, the ratio is 0.039.

    The largeness of $0.50 or $0.75 in royalties on the $4 gas deal, compared to the whole U price, explains much of the eagerness governments show in hobbling nuclear energy.
