Question

Nuclear energy comes under the category of renewable or non renewable sources of energy . comment?

Answer 1

Non-renewable.  Once the plutonium rods have been spent, they are not usable again.  

Although there is some research into possibly reusing extracted uranium from the spent rods, it's still in the experimental stage.

Answer 2

It is technically non-renewable because we don't have a constant source producing it like the Sun and stuff.

But we can reuse spent fuel (look up MOX fuel).  France and Japan do it.  Breeder reactors use transmutation to produce more Pu-239 than it burns.  More advanced reactors being researched will burn up other heavy elements.

If we simply just use nuclear fuel once and toss it, then it will only last like a 100 years give or take a few decades.  But with advance reactors and reprocessing... We can have fuel supplies for thousands of years.

Answer 3

Renewables are basically driven by solar energy, be it solar cells, wind, waves, plant matter for making cellulosic ethanol, etc.  Nuclear materials are not made from solar energy, so when we use them up, that's it.
