60 commercially operating nuclear power plants
with 98 nuclear reactors in 30 U.S. states (the Indian Point Energy Center in New York has two nuclear reactors that the U.S. Energy Information Administration counts as two separate nuclear plants).
Why is U-235 used in nuclear reactors instead of U 238?
U- 235 is a fissile isotope, meaning that it can split into smaller molecules when a lower-energy neutron is fired at it. ... U- 238 is a fissionable isotope, meaning that it
can undergo nuclear fission
, but the neutrons fired at it would need much more energy in order for fission to take place.
