reactors use a mix that is only about 5 percent energy - rich uranium - 235; the rest is more common uranium - 238.)
Most nuclear
reactors use uranium fuel that has been «enriched» in uranium 235, an isotope of uranium that fissions readily.

reactors use river or lake water for cooling — particularly at Indian Point, less than 30 miles north of New York City on the Hudson River.
However, when asked to comment, one CEO said Canada is in a strong position because Candu
reactors use heavy water instead of boiled or pressurized water, which allows the reactor to run on natural uranium instead of enriched uranium fuel.
The reactor uses uranium dioxide fuel particles that are also coated with graphite so they will not crack and release fission products even in extreme heat.
