At 5.4% of U235 enriched U238 , it requires infinite mass to reach criticality. You will need at least 20% U235 to reach criticality and you will need hundreds

At 5.4% of U235 enriched U238 , it requires infinite mass to reach criticality. You will need at least 20% U235 to reach criticality and you will need hundreds of kilograms of the stuff.
