US Small-Scale Nuclear Reactor Industry Gains Traction In Missouri

trichard writes with this quote from an AP report: "Ameren Missouri is vying to be the first utility in the country to seek a construction and operating license for a small-scale nuclear reactor, a technology that's appealing to utilities because of the smaller upfront costs and shorter development lead times. The small reactors, about a fourth or less the capacity of full-size nuclear units, are appealing to the nuclear industry because they could be manufactured at a central plant and shipped around the world. By contrast, building nuclear reactors today is a more cumbersome process that must be done largely on site and takes years."

    Do lots of smaller reactors fail at a rate statistically below or at least equal to a single larger reactor that generates the same amount of power?

      California is the 8th largest economy in the world, or so. It is in no way Communist, perhaps it has some social programs but that is not communism. Communism is a real thing, not just some slur you use against people wealthier than you.

      I suppose it depends on the design, but a smaller reactor can be built so that if it loses cooling it just shuts down (i.e. the reaction stops), not melts down. I remember reading about this a long time ago, about how we could have reactors in neighborhoods with no problems. Oh wait, here we go:

      "Most [small reactors] are also designed for a high level of passive or inherent safety in the event of malfunction. A 2010 report by a special committee convened by the American Nuclear Society showed that many safety provisions necessary, or at least prudent, in large reactors are not necessary in the small designs forthcoming."

  3. These can be boons for small towns... by mlts · · Score: 5, Insightful

    For a small town, a small (~220 MW) plant will come very handy. It helps ensure they will be up if the grid goes down, that businesses would have a utility power guarantee, and it also gives clean power without having to deal with a coal or other fossil fuel plant.

    I keep seeing these pieces of a puzzle popping up on /. that would solve the core problems our culture faces. A wind turbine to pull water from the air here, small reactors there, isobutane from CO2, better batteries from IBM, and self driving cars. Putting these technologies together, and we have done a lot for the transportation infrastructure. The reactors would give reliable power, which can be used to charge batteries on electric vehicles or make usable fuel for IC engines. Road congestion and even the need for a vehicle (as opposed to just renting one for a trip) would be eased by self driving cars.

    I just wish some of these cool potential ideas came into practical use. Self driving cars would allow for a lot of flexibility especially.

    As energy availability improves, so do economies.

  5. Small Scale Nuclear Power Plants... by bjwest · · Score: 4, Interesting

    have been in use by the U.S. Navy for decades. They've plenty of safety and failure rate data on them, they've got a high safety rating, and they're pretty small. Start mass producing them suckers and they'll be cheap as hell. Start peppering the power grid with them here and there, and soon we'll have clean, virtually unlimited power. Most counties in the country can get by with one, and still have plenty of power to spare which can be sold off to the larger cities that need would more than one.

      They also require weapons-grade uranium for fuel, which kinda rules out their use in civilian applications.

    The small reactors, about a fourth or less the capacity of full-size nuclear units, are appealing to the nuclear industry because they could be manufactured at a central plant and shipped around the world. By contrast, building nuclear reactors today is a more cumbersome process that must be done largely on site and takes years.

    That's an editorial addition by the submitter - and not part of TFA. And it's not quite right either.
     
    Regardless of the size of the plant, the major machinery is built off-site and shipped to the construction site for installation. What's time consuming and expensive on site (and it's not clear that small reactors escape this) is the labor intensive work of hooking up all the piping, wiring, and ancillary systems for the plant.
     
    What saves time and money in this kind of construction is eliminating building major machinery only on demand, and instead building it at a slow but steady and predictable pace. I.E. if you can negotiate to buy April's production in February of the previous year, you have less capital tied up (and thus pay less interest) than if you had to order your machinery two, three, or four years in advance. Though standardized serial production isn't quite the same as mass production, it has the same benefits to a lesser degree.
