Nuclear Energy is (can be) Renewable

• Nuclear energy is not renewable if we discard nuclear fuel after one use.  This uses, and wastes much of, the only fissile nuclear energy source, uranium-235.  The U-235 is just 0.7% of natural uranium.

• But nuclear energy is renewable if we recycle the fuel. The U-235 can then convert the billions of tons of uranium-238 (99.3% of natural uranium) into more fuel.  (There are 4.5 billion tons of uranium recoverable just from the oceans.)

• The world also has four times more thorium than uranium; which we can then also convert to U-233 as fuel.

• Therefore, our nuclear fuel supplies can be ever-increasing; to be renewed for billions of years.  This defines “renewable energy.”
