Hanford Nuclear Waste Cleanup Makes Progress, But Questions Loom (ieee.org) 121

Posted by BeauHD from the only-time-will-tell dept.
The Hanford Vit Plant in Washington state, a $17 billion federal facility for treating and immobilizing radioactive waste, is now on track to begin "glassifying" low-activity nuclear waste as soon as 2022, reports IEEE Spectrum. This is "a year ahead of a court-mandated deadline." From the report: Still, an air of uncertainty surrounds the project. The U.S. Department of Energy (DOE) has proposed reclassifying some of the nation's radioactive waste as less dangerous, and it's unclear how that could affect the Hanford facility's long-term prospects. Hanford houses about 212 million liters of high-level waste, the leftovers of the U.S. nuclear weapons program.

However, higher-level waste has a longer timeline. Separate pretreatment and vitrification facilities aren't slated for commissioning until 2033. All parts of the Vit Plant are legally required to begin fully operating by 2036, under a consent decree between Washington, Oregon, and the federal government. The DOE hasn't said whether, or how, its proposal to reclassify nuclear waste would affect existing plans at Hanford if adopted. The agency is not making any decisions on the classification or disposal of any particular waste stream at this time, a DOE official said by email. [...] Though current law defines high-level radioactive waste as the sludge that results from processing highly radioactive nuclear fuel, the DOE is considering slapping a new, potentially less expensive label on it if it can meet the radioactive concentration limits for Class C low-level radioactive waste. Reclassifying nuclear waste would allow the federal government to sidestep decades of cleanup work, saving it billions of dollars. The relabeling might even enable the DOE to bypass costly vitrification and instead contain tank waste by covering it with concrete-like grout, as the agency does at other decommissioned nuclear sites. Officials and citizens in Washington and Oregon oppose this method for Hanford, "citing the risk of long-term soil and groundwater contamination and the challenges of moving and storing voluminous grout blocks," reports IEEE Spectrum. "Earlier federal studies found that grout 'actually performed the worst of all the supplemental treatment options considered.' (A 2017 report to Congress, however, suggested both vitrification and grout could effectively treat Hanford's low-activity waste.)"

This Slashdot story is a good example of demonstrating the confusion and inadequate management.

      THE most important problem with nuclear power ? COST.

      This article is about nuclear waste from weapons productions left over from the 60s. This has nothing to do with nuclear power. No civilian operation wants anything to do with the processes involved with Hanford. They used acid to separate Plutonium from Uranium. The acid mixed with the Uranium is the waste. Civilian nuclear power has never done anything like this, doesn't want to and almost certainly never will.

      • Not exactly. Reprocessing to extract Plutonium and unburnt fissile Uranium is absolutely a civilian thing, and still uses nasty nitric acid, although much of the waste at Hanford is from earlier processing that was a lot less efficient. France and Japan have done a lot of civilian reprocessing in recent times.

        Most (in excess of ninety percent!) of the U-235 fuel in modern commercial light water reactors is not burnt, due to the accumulation of "neutron poison" reaction products that kill the reactions. A b

        The problem is not even the cost; its how the deal is structured. Everyone loves to look at coal/gas/oil etc and argue the total costs including the externalized ones like increased respiratory disease add up to more than nuclear and maybe even add up to more than costs associated with neuclear disasters like Japan.

        The problem is that when something like Fukushima happens the costs are incurred up front are enormous large areas of property are lost immediately. Massive amounts of money have to be poured into cleanup and containment; even as compared to an ash or oil spill.

        The costs of the other energy choices however even if greater are borne out over time. Society remains productive during that time and pays them in what are effectively installments. We can live with it. The same way individuals can live with mortgage payment of $800 a month but would be bankrupt if you required them fork over $200K this afternoon.

        • We already do this to collect the closing costs of a nuclear plant. For every dollar a customer pays for electricity generated with nuclear power, a few cents go into building up a fund to pay for the cleanup of any accidents. Japan's nuclear plants have produced roughly 200 TWh per year [wikimedia.org] for the last 30 years, or 6000 TWh. The Fukushima cleanup cost is currently estimated at $180 billion [bbc.com]. So its cost relative to the amount of power generated is ($180 billion) / (6000 TWh) = $30 million / TWh = $30 / MWh

        Eh. Even the monetary cost is overblown and largely due to NIMBYs. Do the math on what it would cost to provide conventional fuel for an aircraft carrier for 60 years, vs what it costs to make them nuclear. Include decommissioning costs for good measure. You'll still get a very favourable result.

      What is the cost of power if you fold in all the externalities of each type? As an example, coal kills 10,000 people a year. The EPA uses a value of $7.4 million (2006) per person in their statistical analyses. What's the cost of carbon dioxide that should be assessed? Should there be some credit to nuclear for having a capacity factor north of 90%? The dollar amount is not the whole story. I don't know enough about solar or wind externalities to say anything about them, but you'll need a bunch of storage to smooth out power delivery. What does that cost at grid scale?

      The thing is we need responsible adults in charge of nuclear power. But because of the political visibility of it we have elected politicians putting their hand in it.
      So instead of these power sources being controlled and managed by experts and people with in depth knowledge of the risks and advantages, with careful planning and solid execution. There is someone at the top who won a popularity contest, often because they are either the best spoken, or relates well with the common man. Not because they are a smart humble public servant, who is looking out for the well fair of their constituents over their next election cycle.

      In Americas two party system both parties are bad for nuclear power.
      The Republicans, want to spend less money, forcing Nuclear power company to cut corners. Which normally goes into safety first, then will then go into reliability. They will stand up and support Nuclear power, but try to cut out expenses that are needed for a long term success, and regulations to make sure things are being safe.
      The Democrats, generally want to stop nuclear power. So they will not go out of their ways to make such companies succeed. They will be more apt to shutdown a power plant then spend millions of dollars for needed upgrades, even if shutting it down will cost twice as much.

      Then we have the political parties swapping back and forth regaining and loosing power. Which is forcing an industry that really needs a long term consistent plan, spanning multiple generations, to be hit with rapidly changing methods and rules. It is like bending a wire back and forth, after a while it will snap.

          You understand that restarting reprocessing fuel has been discussed a number of times, both at Hanford AND Savannah River. And both of these sites store significant amounts of radioactive waste we need to dispose of.

    This argument has been going on for years. On one hand, the DOE keeps changing the rules for vitrification, and processing, and keeps the shell game going at Hanford. On the other hand, they've shut down the Savannah River reclamation project, and mothballed Yucca Mountain. So, we keep kicking the can down the road, and in the meantime, the storage containers that currently exist at Hanford are getting older and more subject to decay and leakage. It's going to take another crisis for them to make a definitive plan - but I don't know why I expect anything less....
