Converting Plutonium: Nuclear Reactions for Harmlessness

[RJ Emery]

Suppose one had on hand a supply of plutonium. Suppose also one wished to render it harmless. By what nuclear reactions could plutonium be made into something relatively benign?

 

[Norman]

What isotope of Plutonium are we talking here?

 

[RJ Emery]

All forms.

 

[Norman]

Well, to make it useless for weapons (Pu-239 that is) you could just transmute it to Pu-240.
