Difference Between Fissile and Fertile Isotopes

WebA critical mass is the smallest amount of fissile material needed for a sustained nuclear chain reaction. No mention is made of a neutron moderator in this definition. If critical mass is defined like this, then that should allow infinite moderator material to be used if doing so would lead to the minimum amount of fissile material.
