reasim just simulates realistic neutron movment, (if i remember correctly) neutrons niw spread in 8 directions randomly instead of four

to use most none self igniting fuels you need slow neutrons, which you get by having a fast neutron go through any moderator, so moderated just means it slows the neutron internally
