Weapons grade spheres of plutonium need reflectors because they are just below critical mass, and the reflector pushes it slightly into criticality. There’s nothing stopping you from making it a critical mass in the first place. Accidents have occurred with liquids at power plants where enough of it was pooled together to achieve criticality without a neutron reflector.
Nononono whyyyy is it emitting plutonium, the plutonium would be emitting radioactive particles D:
Also, it likely wouldn’t glow blue since there are no reflectors, so it wouldn’t reach criticality.
I love this one regardless :)
