That could allow reactor operators to squeeze extra energy out of fuel rods before refueling: The rods are typically replaced after four or five years in a reactor, and degradation of the cladding is a major limitation on their longevity.
NuScale Power has created a new kind of nuclear power plant - a smaller, scalable pressurized water reactor with passive safety features, allowing shutdown and self - cooling, with no operator action, no AC or DC power, and no external water.
