solution: contain hundreds of neutrons and nuclear within titanium shell
imma try using this in one of my reactors. thank you. +1
my slow neutron decided to miss the nuclear fuel
@JusticeFighter well reflectors increase the time neutron spends in reaction zone so its the same thing
Instead, the reason is because the (rare) U-235 atoms react better with slow neutrons than with fast neutrons, while the (common) U-238 lets slow neutrons pass by much better than fast neutrons, so reactors don't need their fuel to be enriched (filtering out U-238, expensive process)
This is not the reason why reactors have neutron moderators - how long a neutron is in the reaction area doesn't matter, because the reaction area walls are reflective
