But then again, like transmute said, these neutrons could also be harnessed to remediate existing stockpiles of the most wicked and nasty legacy of the Cold War and Arms Race.
Focusing neutrons is inherently difficult or impossible, since they are uncharged. They radiate in a statistical sphere. So now you have a shell of nasty-legacy isotopes.
The complications really multiply exponentially, don’t they? 😆
There is a neutron reflector used is many fission reactors called a “neutron reflector”. It is made of graphite whose crystal structure is specially designed and manufactured to reflect neutrons to a high degree of efficiency.
Certain types of fusion/fission combo hybrid reactors(thorium) does not produce any long lived nasty-legacy isotopes. Sorry!
