US Freezes Nuclear Power Plant Permits Because of Waste Issues 347
KindMind writes "The U.S. Government said it will stop issuing all permits for new plants and license extensions for existing plants are being frozen due to concerns over waste storage. From the article: 'The government's main watchdog, the Nuclear Regulatory Commission, believes that current storage plans are safe and achievable. But a federal court said that the NRC didn't detail what the environmental consequences would be if the agency is wrong. The NRC says that "We are now considering all available options for resolving the waste issue, But, in recognition of our duties under the law, we will not issue [reactor] licenses until the court's remand is appropriately addressed." Affected are 14 reactors awaiting license renewals, and an additional 16 reactors awaiting permits for new construction.'"

Actually spent fuel is more a regulatory problem than anything else - it's typically almost entirely perfectly good fuel contaminated with just enough fission-damping byproducts to make it unsuitable for the reactor it was in. the problem is just that nobody particularly wants to reprocess it when the incremental cost of mining fresh stuff is so much cheaper than the capital costs of building fuel reprocessing plants.
The other alternative is of course to move to more efficient reactors in the first place - even just doubling or tripling the efficiency (typically in the low single digit %s now) would dramatically reduce the waste flow, and most thorium-based reactors are typically projected to operate up in the 80% or higher range, leaving only short-lived "ash" that would decay to background levels within only a few hundred years, and many designs would incidentally be able to consume existing "spent" fuel as a percentage of its load. Not to mention the benefits of a fuel that needs minimal processing and is currently a waste product of many rare-earth mining operations.
Its worth nothing as well that the reason current reactors produce so much plutonium waste is that they were designed to do so - they're almost all based on the fuel cycles researched early on when the driving force in the field was nuclear weapons research and plutonium was in high demand.

Stop and think about that for a moment. You have a thorium reactor which produces much harder to handle ash as waste, and which itself becomes highly radioactive and difficult to decommission. From a commercial point of a view waste that decays in a few hundred years is no different from waste that decays in a few million; it still has to be dealt with now which eats into shareholder profits.
Oh, and then there is the small matter of actually developing a commercial thorium reactor and getting it certified.

Most uranium mines historically range between 0.1 to 0.5% U3O8, or 1 t0 5 grams of Uranium oxide per tonne of dirt. If you chose vitrification, you would need to turn more than 300 tonnes of ground up rock into glass for every kilogram of yellowcake produced. Tailings also have a high volume of water which is hard to evaporate completely (tailings dams form a crust quickly, the slurry left behind remains semi-liquid for years). Heating so many tonnes of damp tailings would generate immense amounts of toxic, corrosive, radioactive steam, which would need to be contained and managed separately. You would also need to transport the tailings to a vitrification plant, increasing costs, probability of contamination and adding pollution.

Unfortunately while recycling works to extract useful fuel, since that is a small percentage of the total it does nearly nothing to reduce the amount of high-level waste posing a storage problem. It's also a very complex and hazardous process, far more so than refining raw ore was originally. An additional problem is that some of what is recovered poses even greater weapons-related concerns than the original fuel. France, which processes more spent fuel than anyone else, still does so with only a small percentage of what they produce.
Beyond coping with products of normal fuel production, operation and dismantling, Japan has vast amounts of contaminated material to put somewhere. Someone was joking that they should make another island out of it, and have some government, power industry, and banking officials live there.

As for meltdowns - yeah, ugly things.

That's only about 20 years of experience to go into their design, without any major catastrophes having occurred to inform their risk-management - compared to the 70 years and multiple accidents worth of paranoia going into modern reactor design. Probably the biggest problem with fission reactors is that the vast majority are still based on designs driven by weapons research (i.e. goal #1 was extraction of weaponizable byproducts). CANDU is the only in-use design family I can think of offhand that was designed from the ground up to be a power plant - and while a "meltdown" in such a reactor would be costly to repair it's highly unlikely that anything particularly radioactive would escape the core.

For some reason people hear "Coal Fired" and think of an old steam locomotive gobbling up tons of coal while producing a comparatively small amount of steam power and spewing tons of smoke and ash and unburnt coal into the air.
The reality is FAR from that. Here in Buffalo we have a coal fired power plant that produces large amount of power for the area. (No, we don't get most of our power from Hydro, most of that is sent all the way across the state to New York City.)
I have been into this plant and seen how it works. Much like Nuclear, the coal is used to generate Steam which is used to turn turbines. However, the efficiency is MUCH higher because of how they burn the coal. Essentially, the coal is pulverized into a powder somewhat finer than talcum powder. it is dried with hot air (about 650 F) and then blown with even hotter air out of a compression nozzle into the firing area of the boiler. The pressure from the nozzle heats the powered coal and air to the ignition point and you get a blowtorch of incinerating coal dust and air blasting out of the end.
Not only does this create tremendous amounts of heat (which is used to generate steam, like a Nuclear power plant) but it much more thoroughly burns the coal, (something like 70-80% burned) leaving just a tiny fraction of ash left, which is removed from the exhaust air by scrubbers. Modern coal fired plants produce ALMOST NO airborne waste, and contribute far less to air pollution than diesel plants of similar generation capacity. They also produce no radioactive waste, so the lasting environmental effects are minimal.

Chernobyl was possibly the worst stereotypical example of batshit-crazy Soviet-era negligence I've ever heard of. [...] The Fukushima disaster resulted from similar incompetence.
This special pleading is typical engineer mentality. "Don't blame the technology, blame the humans!" Yes, fine, but the fact is that all of these plants are operated and managed by humans, and there will continue to be errors due to all those messy irrational things that humans do (politics, cost-cutting, negligence, incompetence, etc.). When those errors take place in nuclear power plants, bad things can happen. While better-enforced regulations can help, you'd be a fool to think that we're never going to have more nuclear accidents.

Fine, whatever. But if you want to climb onto your high horse and preach about the amount of radioactive material released, why pick on a few isolated unintentional nuclear accidents? Why not cite the thousands of nuclear weapons tests that were deliberately conducted during the Cold War? Any one of those tests probably released more radioactivity into the air than Fukushima, and we know for a fact that people have died as a result. But did they ever kill 13,000 people a year [www.catf.us]?
(Admittedly, that's probably some kind of nuclear-industry astroturf site, but I'll still stand by the point that we would never tolerate the environmental harm caused by coal-fired plants if it were as obvious as a Fukushima or Chernobyl.)

When asked why these results haven't been widely reported, Calidcott noted that Japanese officials are not sharing ultrasound results with foremost experts of thyroid nodules in children and accused the media of "practicing psychic numbing," saying that she doesn't understand why media outlets are choosing to ignore the nuclear fallout.

When the above four studies are tallied in one table, it becomes obvious that the result of the thyroid examinations of children in the “Fukushima Prefecture Health Management Survey” is astonishing. This is because one-third of the children had developed “ cysts.” A “cyst” is a fluid-filled sac. Cysts don’t mean there is an immediate chance of developing thyroid cancer. However, it is apparent that something extraordinary is happening inside the thyroid gland, such as inflammation or changes in cellular properties.
Summarizing the thyroid ultrasound examination results from Japan and overseas, prevalence of “cysts” detected in children around the age of 10 is approximately 0.5-1.0%.
The fact that 35% of Fukushima children (average age around 10) have thyroid cysts strongly suggests that these children’s thyroid glands are negatively affected by undesirable environmental factors.

In June [2012], 56 percent of Japanese fish catches tested by the Japanese government were contaminated with cesium-137 and -134. (Both are human-made radioactive isotopes—produced through nuclear fission—of the element cesium.)
And 9.3 percent of the catches exceeded Japan’s official ceiling for cesium, which is 100 becquerels per kilogram (Bq/kg). (A becquerel is a unit of radioactivity equal to one nuclear disintegration per second.)
The numbers show that far from dissipating with time, as government officials and scientists in Canada and elsewhere claimed they would, levels of radiation from Fukushima have stayed stubbornly high in fish. In June 2012, the average contaminated fish catch had 65 becquerels of cesium per kilo. That’s much higher than the average of five Bq/kg found in the days after the accident back in March 2011, before cesium from Fukushima had spread widely through the region’s food chain.
In some species, radiation levels are actually higher this year than last.

That "radiation that a functioning nuclear power plant releases into the surrounding environment" is a tightly controlled quantity and should be as close to "none" as possible. That number does not include the radioactive waste that the plant generates, because the intention for the waste is to not release it into the environment. Sometimes, however a nuclear power plant does release more than the normal amount of radiation, and then usually it's bad enough to be referred to as a 'disaster', with greatly in

The shutdown Sequoyah Fuels uranium conversion plant is disposing of low-level radioactive waste by spraying it on 9,000 acres of company-owned grazing land.
Of course, they have good reason to spray it around.
"The U.S. Nuclear Regulatory Commission (NRC) is considering issuance of a license amendment to materials license SUB-1010 to authorize decommissioning of the Sequoyah Fuels Corp. (SFC) site near Gore, Oklahoma. This license is issued to SFC to possess contaminated material at its Gore site. NRC licenses these facilities under 10 CFR part 40. Specifically, the license authorizes SFC to possess up to 20 million metric tons of source material in any form. The contaminated material at the Gore site is in the form of uranium, uranium oxides, uranium fluorides, thorium, radium, and decay-chain products in process equipment and buildings, soil, sludge, and groundwater."
