(theenergycollective.com)
  • In addition to my first-hand experience in operating and maintaining submarine nuclear propulsion plants, which are far smaller than commercial power stations, one of the main reasons that I became interested in designing and building smaller commercial reactors was the experience of reading I. C. Bupp's Light Water: How the Nuclear Dream Dissolved . (theenergycollective.com)

  • Individually, these nuclear reactors would produce less energy than traditional reactors, but could be used more flexibly and operate more efficiently. (popularmechanics.com)
  • These easy-to-install reactors could potentially shave years and millions of dollars off the construction of nuclear power plants, and could make it economical to bring nuclear power to rural areas or developing countries that lack infrastructure. (popularmechanics.com)
  • By contrast, small reactors such as the Westinghouse SMR would rely on gravity and thermodynamics to circulate coolants. (popularmechanics.com)
  • But small light-water reactors may eventually deliver electricity that is less expensive than what larger reactors can produce simply because construction and installation costs would be lower. (popularmechanics.com)
