What do they mean when they say they are bombarding the fuel with neurtons? What makes the reaction start?

I am not a science guy, but I have been trying to find out how a nuclear plant works and I think I get it; however, I am not clear what it means to bombard something with neutrons. I think I understand how the process continues due to the chain reaaction, but how do you start the reaction.
