I haven't made any claims. If there are nuclear reactors, show some practical demonstrations of "the claim", nuclear fission - atoms being split.

That is the model and should be able to be practically demonstrated or an experiment shown to PROVE the claim? That's how science works in the real world.

The original experiments were conducted without any special conditions so records of them should be readily available and verified 100s of times over by now in the scientific community to gain consensus.
