Is this Natural Reactor dangerous to animals / plants around the Reactor? Is the radiation cause DNA damage / evolution?
No, it's not dangerous anymore, save for the fact the area will probably have a higher background level of radiation; and the fact that the nasty gas radon poses a threat to anything that breathes there for a longer period of time. Second question: hard to say: the reactor was operational 2 billion years ago, meaning there wasn't any life worth mentioning in the vicinity. If there were, yes, it would have caused DNA damage, just like a modern reactor does today.
Is it possible to create a small, simple, portable and SAFE Nuclear Reactor for generating energy?
First define what you think is acceptably safe, then we'll continue the discussion :-).
