U.S. Nuclear Cleanup Carries Major Risks 522

Roland Piquepaille writes "New Scientist reports in this pretty alarming article that there is a 50-50 chance of a major radiation or chemical accident during the cleanup of the dirtiest nuclear site in the U.S. There are indeed lots of things to clean at the Hanford complex in Washington state: 67 tons of plutonium and 190 million liters of liquid radioactive waste stored in underground tanks. A third of them, dating from the Cold War, have already leaked 4 million liters in the environment, contaminating the groundwater and a river. Meanwhile, officials at the DOE, who'll spend $50 billion between now and 2035 on this cleanup, seem less worried than the different specialists interviewed by New Scientist. Please read this overview for selected quotes from the article and from the Hanford site. You'll also find a slide from the DOE showing the timeframe for the cleanup."

        From link (which is a 3 year old article): "See that," Berry says, pointing to the seeming nothingness pouring out of Polk's stack. "Someone can be sitting near a coal gasification plant and see nothing coming out of it. That's the goal." (In actuality, the clouds pouring from traditional plants are water vapor.

        While most clouds you see coming from stacks are simply water vapor, a coal fired boiler emits a lot of particulate matter, which is harsh on the lungs, especially to those with asthma or other respiratory problems. The EPA has been focusing more on PM in the past few years. Facilities are now required to report PM emissions at 3 levels: Total PM, PM10 (PM 10 microns or smaller), and PM2.5 (PM 2.5 microns or smaller). PM2.5 emission reporting was added just this year, as it has been learned over the past 5-10 years that PM2.5 is much more harmful than less fine particulates. Current control measures for PM are in the 99% removal range, assuming the equipment is properly maintained.

        Also, coal emits a lot more crap than oil or natural gas. By crap I mean trace amounts of nasty chemicals. Hydrochloric acid, hydroflouric acid, arsenic, mercury, lead, dioxins, etc. EPA's emission manual for coal combustion can be found here [epa.gov].

        "Clean coal" may be a temporary measure as we begin to run out of natural gas and oil, but it is by no means a solution, as the CO2 problem is not solved.

        It's the old ones (especially in places like China) that are the problem.

        Yes, but the real problem is our reluctance to fund new energy initiatives and promote smart usage of energy. We waste outrageous amounts of energy in the USA. Research must not only be focused on new energy sources, but improved efficency in the transmission and use of that energy.

    • No kidding. Can any nuclear scientists comment here? AFAIK, Plutonium is a fairly innocuous problem. It's heavier than just about everything, so it doesn't float. It's not water soluble, and it primarily releases Alpha particles (a non-threatening form of radiation). Unless they're leaking something like Strontium-90, Iodine-129, or something fresh out of the reactor with a half-life of three months, then I'm not particularly worried.

        Plutonium is far more toxic than radioactive (as far as hazards go). What I mean by that is that it takes fall less PU to kill you by poisioning than required to cook you with radiation.

      • It's not water soluble, and it primarily releases Alpha particles (a non-threatening form of radiation)

        Not really correct: Alpha particles are stopped by a sheet of paper. But if you ingest plutonium or inhale it, then it's one of the most dangerous substances around.

      Very interesting point, and you may, or may not, be surprised to hear that in fact coal-burning industry, mostly power plants nowadays, has released far more uranium, thorium and radium (plus others?)into the atmosphere than the entire nuclear industry, and they continue to do so.

      This is because coal contains trace amounts of these elements, which are not in the form of particles, but are more likely distributed as individual atoms in individual molecules, maybe combined with carbon, certainly oxygen, and other elements. No known technology can take individual molecules of, say, uranium oxide, out of a chimney.

      Now this release of radionucleides has been going on since serious use of coal began around 1600-1700.

      Interestingly enough, in the UK there is often controversy over so-called leukaemia clusters, now these cases are tragic, but it is alleged that they are due to the nuclear industry, however close inspection shows that every single such cluster, with one exception, is in an area close to or downwind of a large coal-burning plant which either still exists, or was in use relatively recently. Some of these plants were lead smelters, which adds more uranium and other toxic elements. The one exception that I know of, where no industrial presence can be seen, is in Cornwall, around the village of Tintagel, and it is hardly surprising, because the local children no doubt play on their nice beach, and behind the beach are sea caves, with uranium compounds leaching out of the rocks. There will also be a high concentration of radon gas in such places, it mainly causes lung cancer by depositing daughter products in the lungs, but some of the daughter products may indeed cause leukaemia, and may be ingested in other ways.

      At a guess, I would say that similar conditions of radiation release due to coal burning, and the extraction of certain other minerals, will be found worldwide, as presumably volcanic activity had released lots of radionucleides into the atmosphere during the carbiniferous era, which would eventually have found their way into the vegetation, and hence the coal.

      In one particular part of the UK, when germanium transistors were in fashion, soot from factory chimneys was collected because it was rich in germanium, I think you will find that other elements (certainly selenium, which is toxic and carcinogenic, and also cadmium) can be found in significant quantities in some geographic regions.

      So, coal burning will release radioactive, toxic and carcinogenic substances, fortunately not plutonium of course, although in theory an occasional atom might be formed by natural processes. After all, there are these odd atoms of uranium embedded in the moderator, coal instead of pure graphite, so there is the remote chance that a neutron from a fissioning uranium atom might be slowed by the coal, and captured by another uranium atom. But the yield would be incredibly low.

      Over the last 50 years nine reactors at the 1500-square-kilometre site have produced 67 tonnes of plutonium for the US nuclear weapons programme. In 2002 the US Department of Energy (DOE) embarked on a 30-year, $50 billion clean-up, which includes emptying more than 190 million litres of liquid radioactive waste from 177 underground tanks.

      In this Hanford overview, the numbers are slightly smaller than the ones provided by New Scientist, but are still worrisome.

      Physical challenges at the Hanford Site include more than 50 million gallons of high-level liquid waste in 177 underground storage tanks,

      Last I checked, the DoE ran the Pantex nuclear weapons plant [dnfsb.gov]. The same site with some obscene safety issues [theregister.co.uk].

And that's ignoring the clichéd "OMG THREE MILE ISLAND" commentary.

      Perhaps you reached this conclusion because the security teams were cheating during their security drills [wired.com] ? Cheating. for twenty years. It's not too hard to look impenetrable when you know the exact building and wall [doe.gov] where an attack will take place. A DoE whistleblower admitted to a 50% success rate [washingtonpost.com] for security tests. Special forces teams were able to penetrate Los Alamos [pogo.org] and wander off with enough material to create a nuclear bomb. Even an freakin' journalist was able to sneak into Los Alamos [defensetech.org]. There are plenty of other issues raised [pogo.org] over at the Project On Governmental Oversight [pogo.org]. Again, that's ignoring all the major security issues with CREM's going on over the last month.

      Now, you're absolutely right in the fact that we need to get that waste cleaned up. But thinking that the DoE, NNSA, or the US government on the whole is "more than capable" is bullshit. We're flirting with disaster. If we take the outlook that everything is fine and dandy, we're going to quickly hit the point where someone will cause a situation of calamatious proportions.

    • We store acids in glass beakers because the acids don't eat the glass. The problem with radioactive "waste" is that the radiation acts to wear out the container over the long term. Right now I think we mostly mix the waste in with glass, which is better than just pouring it into a metal drum because the metal drum would wear out faster (than glass).

      Radioactive materials are sometimes called "hot"; they can be warm to the touch; this comes from the fact that as decay occurs particles come shooting out of the nucleus. These particles can hit other nuclei and jostle molecules around.

      IIRC, the most recent containment technology is based on storing the "waste" in crystals, eg Zircon. The upswing of crystal storage is that the "hot" material in the center of the crystal degrades the inner part of the crystal, which reacts by forming a "wall" instead of cracking or oozing. Kind of like when you crumple a piece of paper, and there's a limit to how much smaller you can make it by squeezing. Okay, maybe that's a poor analogy, since the "squeezing" comes from the inside, but you get the idea.

      Here's a link. [bbc.co.uk]

      FWIW, if we had a space elevator, would anyone object to putting nuclear plants on it? It's not in anyone's backyard, and it's well placed to sling the crud into space... if we can find a target. I say Mercury.

      Nuclear is one option we should pursue. We should also keep working on bio-fuelcells and wind/wave. It all comes from the sun (well, A sun...) anyway. This is all going to be moot once we bootstrap a stellar economy.. there's more methane and natural gas to be had than well, even humans could waste (okay, maybe not, but there's a lot).

      Plutonium is made by transmutation in a nuclear reactor. Transmutation produces not just plutonium, but a whole range of transuranic elements. These are then separated chemically.

      Both uranium and plutonium extraction are very messy processes from a chemical engineering standpoint. They involve highly corrosive materials, including fluorine and acids. During the chemical processing, the corrosives become mixed with radioactive byproducts. So you get liquid mixtures which are both corrosive and radioact


    • This is a weapons site, so they were going as quickly as possible to beat the soviets. There was no time (so it is said) to handle this properly, so they just extracted the plutonium and put the rest of the liquid waste in large tanks underground. This went on for decades. Surprise, surprise, several decades later it was found that some of the waste spilled here, a little leak there, etc....

      It's not hard to properly handle if the site was setup to handle it properly in the beginning. Unfortunately, haste m

      IAAHG ( I am a hydrogeologist ), or at least was an one point. People do not understand the effects of time on engineerd materials. Most engineered materails have a usefull life of a few decades or less. You new roof is water tight today, but come back in 50 years and it will leak like a sive.

      The uinderground environment is a hostile one. There water continually percolating through the ground. This water may or may not be acidic, and may or may not be under perssure. Almost no rock is impervious. It may only leak a little but over 100s or 1000s or yeah a little becomes a lot.

      Anything will leak. The questions are:
      -At what rate
      -And where will the leakage go
      -What happens when some idiot archeaologist 500 years from now opens it up?

      Having an Uncle who for some years was in charge of the cleanup at Hanford and noting that he lives in Kelso I would tend to discount the FUD a lot. (About 99.999999999% or more.) Having two other Uncles who were reactor operations officers for US Nuke Subs makes me have a bit of family based info on the topic. I just am not as worried as most people are because I know generally what the problem is and how big it is.

      To be sure the mess at Hanford is a serious mess. It involves largely the chemicals used to refine the various elemements after reactor actions. The reason they liked plutonium for bombs is that it could be bred out of lesser stuff and was easily chemically isolated. This gave rise to a lot of radioactive chemical wastes which bluntly were pretty reactive stuff.

      The problem was storage was at best using technology we had at the time rather than trying to deal perminanently. The problem is that many of these chemical wastes are liquid and they are stored in containers that are failing or have started to fail.

      The containers in many cases were about equal to swimming pools or to 55 gallon drums. Another problem is some of these elements migrate quite easily through barriers. They form all sorts of funny deposits which if struck are prone to catch fire.

      With all of this said, the whole problem is one more of time and effort than danger. The location is really pretty unlikely to see a lot of migration outside Hanford and if it does go into the Columbia River it will be diluted well below any level of concern. The river is not small. At nearly 100,000 CFS flow and shortly diluted to 200,000 CFS average flow, this stuff is gone... gone... gone.

      To explain a bit more, the problem here is largely one of timing and events. Most of this waste developed right during and shortly after WW2. Shall I say that priorities and for that matter knowlege have changed in the intervening years.

      Actually the biggest problem in the cleanup owes to the need not to actually create more contaminated waste than absolutely necessary while doing the clean up.

        While your post is interesting and somewhat credible, I disagree with your statement that if it does go into the Columbia River it will be diluted well below any level of concern. My dad used to work for Rockwell cleaning up the Hanford waste in the 80's (his job was in part to design ways of cleaning up the waste better), and then went on to work for PNNL. I grew up swimming in the Columbia River. When I was around fifteen he requested that we quit swimming in the river because he had access to informat

    This entire article is based on a study by one person, no doubt with a political agenda.

    I've lived next to Hanford since I was 3 years old, and work a couple of miles from the nuke plant. I've toured the site many times. I've followed local news, which reports on every boring little detail since they have nothing better to do, my entire life.

    Are there problems? Sure. I remember when the single walled tanks started leaking, and they pumped everything into new double-wall tanks. Will there be problems in the future? Sure. Will those problems affect me? No. The accidents that take place may be major to the people working on that particular project, but are not catastrophic in the grand scheme of things.

    Look: The Hanford site has been operational for decades. The number of serious accidents is tiny, and said accidents have only affected the workers directly involved with that given project, not the rest of us. Yes, there are environmental concerns. No, they aren't as horrible as this article makes them out to be. We swim in and eat fish from the river. Our water comes from the river and local groundwater. None is contaminated enough to be detectible, let alone harm somebody. And I'm right here, a fraction of a mile downstream from the site.

    Even if the clean-up goes according to plan, Boldt claims there will still be 260 square kilometres of groundwater exceeding drinking water safety limits for over 10,000 years.

    He's full of himself. This is nothing more than paranoid scare tactics.
  • Well, this person is obviously deeply worried.

    However, he doesn't say what he wants. Does he want to delay the process, and why does he think that will lead to a better risk management than the current plant? Has he got any suggestions for how the risks can be mitigated?

    IMHO, Alvarez comes across as a person that does not want this cleanup to take place at all because that may lead to nuclear power not becoming mainstream if an accident occurs during the cleanup.

    The production schedule for the new Vitrification Plant is far ahead of the basic science and engineering that form the foundation for its construction. Although I do not think that they will operate it with the risks for steam explosion that the article alludes to, it is more likely that the tax payers will pay more than the estimated $7B to construct it.

    You heard it right, folks - $7B.

    As for the groundwater contamination, that is nothing new. A tritium plume extending from the 200 Areas (where plutonium separation was performed) to the Columbia River has been in place since production started. It has fluctuated in size according to the politics of weapons production. The facilities have been shut down since the early 90's and are in various stages of decommissioning.

    The issue of iodine-129 is a sticky point. It has a long half-life and had been dumped to the soil column without too much worry about the transport properties of the nuclide. It travels at the same rate through the vadose and groundwater as nitrate. It is very mobile. The toxicity of the isotope is in come dispute. I can get a higher radiation dose from a urniary test than I can get from consuming contaminated Hanford groundwater. I can also dispose of the contamination through my municipal water treatment facility, a practice prohibited for Hanford contractors.

    As for the cesium-137 and strontium-90, those isotopes bind to soils high in the vadose and rarely reach groundwater. The are confined to zones near the surface, far from the river, and will be left in place to decay to background beneath low permeability covers. This is not a practice that the USDOE is forcing on the local community, but is a treatment alternative that is accepted by the USEPA and Washington Deparment of Ecology.

    The contaminated river in question is the Columbia. [usgs.gov] As the second-largest river (by flow) in the lower 48, and the largest to drain into the eastern Pacific ocean, I think it merits a mention by name.

    But then I'm a local, so I'm biased.

    Thankfully, the large flow means that the contamination is pretty dilute. The bad news, of course, is that said contamination flows through quite a few populated areas (including Portland), the river is used to irrigate and transport zillions of tons of wheat and other edibles, and lots of fish get pulled from the river and eaten.
  • The biggest problem with nuclear waste is the insistence on a perfect solution before anything is done. We've debated and studied for decades the merits of burying the stuff at Yucca Mountain, but in the mean time leave it sitting close to population centers in rusting storage drums.

    Anti Nuke groups actually love this situation because it insures to keep the crisis mounting, and discourages any future nuclear development. Then if and when a nuclear waste incident occurs they can point and say "I told you so."

    Why not go for better storage now, and keep looking for storage/disposal/reprocessing solutions to use later?

    One way to accelerate the solution to a problem is just to redefine it. Here's one such bright idea, hatched by the DOE: "If we reclassify some of the waste to a lower-level category, we don't need to clean it up. We can just cover it with grout and leave it." Sen. Maria Cantwell (D-Washington State) has a lengthy discussion of this here [senate.gov]. Sen. Cantwell's efforts to short circuit this nonsense may have paid off, as this subsequent statement [senate.gov] seems to indicate.

    Rocky Flats is the factory north of Denver where nuclear bombs were assembled until 1992. It is 12 years into the 14 year cleanup plan, and there hasnt been a major accident yet. The place will revert to a wildlife preserve (e.g. three-eye frogs). There was lots of doom-and-gloom too when evaluating its cleanup plan.
    • the rocky mountain news had a little article couple weeks back about this... namely... there are no red-tape areas in the flats any more, the contamination has been adjudged removed. they're ready to knock down the last buildings. the workers surely got their 45 arms around the issue there. but it's all been put into drums, and moved elsewhere, mostly near aitkin, south carolina, to old DOE production facilities there.
