The latest trend in nuclear is the small modular reactor (SMR), which generates a fraction of the energy of traditional reactors, but at a fraction of the cost. Existing nuclear reactors generate 500 megawatts to 1 gigawatt of electricity.
Nuclear reactors could also be used to produce the electricity needed to split water into hydrogen and oxygen; clean hydrogen could then be used to generate heat for steel manufacturing and other industrial activities, to fuel vehicles, produce synthetic fuel, or store energy for the grid
Nuclear power is presently a sustainable energy source, but could become completely renewable if the source of uranium changed from mined ore to seawater. Since U extracted is continuously replenished through geologic processes, nuclear would become as endless as solar
