Pandora's Promise and the Problem of "Solutionism"

Lasrick writes "Kennette Benedict of the Bulletin of the Atomic Scientists reviews Pandora's Promise, a new documentary that focuses on environmental activists like Stewart Brand who have gone from vehemently anti-nuclear to vehemently pro-nuclear views. Good points brought up by Benedict that weren't really addressed in the film." From the article: "The flaw in the film's approach is its zealous advocacy of one solution — one silver bullet — to meet the tremendous challenges of providing for some nine billion people by 2050, while also protecting societies from the ravages of climate disruption. The kind of thinking that led some of these environmentalists to single-mindedly protest nuclear power plants during the 1970s and 1980s leads them to just-as-single-mindedly advocate a push toward nuclear power 40 years later."

Essential physics and engineering topics on nuclear energy, a roadmap of current water reactor designs, descriptions of safety features and failures, and a compelling case for developing Thorium-based energy. This presentation is simply amazing!

      As far as I can tell, what's coming out the wrong end of a thorium reactor will be a molten salt soup of toxic, possibly very corrosive, and VERY radioactive materials.

      Sorensen advocates a two-fluid design for the reactor itself (thorium blanket and fissile fuel loop), the fissile loop (radioactive and temperature-hot) fuel passes through a heat exchanger, passing the heat into a third loop of molten salt ("cooling salt") which carries the heat out of the reactor and through the power plant. This loop is temperature-hot but not radioactive, it heats air or inert gas to drive turbines to make electricity.

      So you've got three separate loops of molten glop going round in this plant, two radioactive (blanket, fissile) and one not (cooling). The two radioactive loops are circulating through the reactor and also passing though a 'processing gizmo' inside the containment building adjacent to the reactor, I say gizmo because it will probably be bigger than a breadbox but smaller than a truck.

      The thorium blanket loop has a hopper that mixes a pinch of thorium into the glop every now and then (~2.7kg/day, 1 tonne/yr). As it passes through the reactor neutrons from the adjacent fissile loop smack the thorium and it becomes Thorium-233. Which decays later into Protactinium-233. Which decays later into Uranium-233. This process takes ~27+ days so the U-233 the gizmo extracts today from the blanket is the thorium you placed into the blanket ~27+ days ago. The blanket salt glop is hazardously radioactive but (I think, just learning myself) there need only be a couple hundred gallons of it.

      The fissile loop is fed U-233 by the gizmo continuously and as it circulates through the reactor this is where the fission is happening. This is where the heat is generated from fission and bled off into the cooling salt (via the heat exchanger). This salt is hazardously radioactive but I think there need only be a few hundred gallons of it.

      The gizmo pulls waste products (fissioned and decayed U-233) out of the fissile loop as they are produced. One guesstimate I saw is is ~170kg of waste per year (bigger than a breadbox but but smaller than a piano). By pulling the waste out continuously the gizmo prevents it from becoming some of the the nastier stuff that water reactors produce. This LFTR waste is "safe to touch" in ~300 years. These is no free lunch, and making a safe container (casket, vitrified in glass) and finding a safe enough place to store something for 300 years do-able.

      The fissile loop is also where the simple and hideously clever load-following characteristic occurs. Turbine trips, shuts down and heat remains in the cooling salt? Fissile loop gets hotter and expands, reducing the concentration of the fissile material and fission slows down. Start turbines again and cooling salt once again becomes cooler? Fissile loop loses heat and contracts, increasing the concentration of fissile in the core, fission increases. Because this is all happening in well-mixed liquids, imagine the power/heat level of this reactor finding a 'sweet spot' after a conduction delay with no human or computer intervention and keeping itself there. No valves closing or opening, no rods being inserted or extracted by white-knuckled operators. This feature is really cool in the hipster sense.

      The cooling salt loop and the tanks which hold it is where the designs become more massive.

      Very insightful, pointing out the difference between use of water in the reactor and water used for (conductive) cooling. At the moment the word 'conventional' implies the use of solid fuel and a loop of water inside the reactor for moderation and cooling, and the use of phase transition (water to steam then back to water again) to drive turbines.

      [1] Brayton would work with a Pebble Bed Reactor where the solid fuel is encased spherical 'pebbles' of graphite moderator and inert gas such as helium is used for cooling. There is no phase change, the helium remains a gas which varies in temperature.

      One such experiment was the THTR-300 breeder in Germany, which attempted to leverage the pebble concept into reality and managed to do so from 1985-1988, despite some problems managing the solid fuel. It was not a proving ground for Brayton though, the helium was used to heat water in a Rankine (steam) cycle.

      Pebble Bed Reactor designs are also considered to be "walk away safe" despite these problems. The danger of graphite igniting if the reactor is breached and the helium replaced by air seems to be overstated, but there does remain the possibility of ignition if it is reduced to dust (such as in a steam explosion, as happened at Chernobyl) or if it comes into direct contact with the solid fuel at the center of the pebble.

      So both 'conventional' rod-and-pellet and Pebble Reactor manufactured pebbles both share one important characteristic --- the necessity of an extremely critical solid-fuel manufacturing process where a failure of workmanship has undesirable results.

      But I wonder though as a layman (disclaimer!) if there is at least one major unresolvable problem with the pebble concept --- and that is how could you be confident you could take the reactor below critical in the presence of multiple mechanical failures? As compared to the salt concept where gravity alone drains the fissile salts out of reach of the graphite moderators with sub-criticality greatly assured.

      [2] Though your biggest safety win arises from removing all water from within the reactor and its containment building, the power plant itself could employ water to assist in cooling. In coastal areas LFTR waste heat is envisioned to assist in desalinization.

      You still have *a* waste problem - not necessarily a storage problem. However, if we assume storage, it still isn't the same storage problem as uranium fuel gives us. Uranium waste contains actinides with a long (many thousands of years) half-life but still radio-active enough to be a concern. Thorium waste is almost all fission by-products which tend to be highly radio-active, which necessarily means a short half-life, so thorium waste doesn't have to be securely stored anywhere near as long as uranium waste does.

      But if we're going to revisit nuclear power generation, why don't we revisit nuclear waste treatment as well? Rather than storage there is disposal - into the sun or onto the moon or interstellar space? The only problem is that tricky first leg of the journey, but that is probably enough to kill this option... Or there is use. Many radioactive isotopes have medical or industrial uses, so processing to extract these may make economic sense (and so would some research into alternate uses...). Then there's transmutation. Most fission by-products can themselves be easily split into less radioactive (or inert) substances. Why not invest some research money here? It would most likely pay of handsomely in the long run.

      It will depend on the reactor-- if we put thorium in a solid fuel reactor cooled by water, you're absolutely spot-on about the waste problem because zirconium-clad oxide fuel is a particularly inefficient way to convert fissile material into energy. About 90 to 95% of spent fuel is what we put in the reactor to begin with, so it's like putting a log in the campfire and taking it out when it's just got a bit of ash on it.

      If we put thorium in a pebble bed, TRISO, or molten salt, that waste stream is now much smaller because you can get much more energy for the fuel you put in, and it burns more completely. In this waste stream there's almost no transuranics or other actinides which are the lion's share of the thousands-year half-lives people worry about when it comes to spent fuel.

      Thorium cycle primarily solves the scarcity problem for thermal reactors (like the aforementioned water cooled reactors) because U-233 is such a great fit for thermal spectrum. Uranium is pretty darn abundant, but U-235 is about as abundant as platinum, and plutonium isn't as good of a fit for thermal. In fact, if the regulators will let us, the fastest stopgap if we start running low on U-235 is probably to just breed U-233 from thorium with a particle accelerator and blend that with depleted uranium for current reactors. Of course, I'd much rather we be using SmAHTR or LFTR by then since China's planning on building the latter by 2020.

There's a gold rush for these with very little accounting for the true external costs (e.g. water aquifer destruction, fugitive methane, and maybe earthquakes, all being uncosted while wars are driving up the price of oil faster than alternatives can replace it. This means market forces now are out of balance and could cause imprudent envirnmental destruction).

    But fracking can be done safely eventually but may have to be done away from aquifers and with better technology.

      In all seriousness, there are a few guys at ORNL working on a reactor design that's an evolutionary step from pebble bed to MSR: a TRISO-fueled reactor cooled by FLiBe. The fuel is in cartridges, so there's no chance of jamming, the reactor cooling is ambient pressure so you don't need extensive backup cooling systems or a huge containment building, the coolant can go much higher than 300 degrees C, so you can use it with higher-efficiency cycle turbines, it just makes a lot of sense when we've yet to figure out the chemical processing part of a molten salt breeder.

  40. The survival of technological civilization by Mike+Van+Pelt · · Score: 1, Insightful

    The survival of technological civilization depends vitally on energy supply. Which means that the omni-obstructionists and the arithmetic deniers are, knowingly or by being duped, enemies of technological civilization. The alternative to technological civilization is getting rid of about six billion people on a very short time span.

  41. The waste just keeps piling up by Anonymous Coward · · Score: 0

    The problem with nuclear power is that it creates nuclear waste. :) Duh. I talked to a nuclear engineer for a while about some little-used technique that could recycle nearly all of the "spent" fuel. Now, that is very, very interesting. But as it stands, nuclear power may be safe for as long as the planet is in operation (disregarding massive natural disasters...which do happen on occasion), and it's not making any greenhouse gases, but it's steadily churning out stuff that is incredibly toxic and/or lethal, depending on the dose/proximity, to all life on the planet. We just keep storing this stuff at--well, honestly, we don't have a storage solution yet! In the U.S., I believe that most of the spent fuel is still stored on site at the nuke plants. You just have to look at the birth defect and cancer/leukemia/etc. rates in Iraq and Afghanistan to know how bad it could get if, say, a bunch of this waste ever got spread around.
    But this waste, we are asking our future selves to solve the problem, and what if we can't do it then? We just create this stuff that needs to be safe for the next few billion years. How much does our geology change in a few billion years? Quite a lot. My point is we think it's safe now because we haven't had the other end of the shoe drop. And that shoe seems destined to drop it's just a matter of probabilities and that game will be played from now on. Every year, the dice are rolled, and so far, those 10 dice haven't come up snake eyes. A few times we've crapped out and had a plant spring a leak, meltdown, etc. but that's not nearly as bad as it can get, and the fact that this kind of thing happens every decade or so implies that the overall odds for continuing to be safe are not in our favor, at least in terms of the worst possibilities.

    Sandstorms + windstorms are pretty bad for wind generation because they destroy your expensive capital.

    Gobi desert is in the middle of nowhere and the populated areas somewhat close by (India/Pakistan) are separated by the Himalaya mountains.

  45. The Bulletin has lost its way,,, by AWeishaupt · · Score: 1

    The Bulletin used to be good, and it used to be really meaningful and respectable back in the day of legends like Bethe, who were passionately interested in working towards a world free of nuclear weapons, but who tempered that passion with pragmatism and political realism, an understanding that nuclear power is not the same thing as nuclear weapons, and a thorough technical literacy in nuclear weapons and nuclear power.

    Today, though, it has gone disappointingly downhill, and every other thing it publishes seems to be a weak, rhetoric-packed attack on civil nuclear power written by an author who usually has something like a background in political science without experience in nuclear science or engineering.
