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."

      Hydro on the other hand is used for base load because it's cheap to run once you have all the infrastructure - but it's used for peak load as well because it takes less than a minute to start up some very large hydro units.
