Reply to comment by SoylentRox in How do fusion scientists expect to produce enough Tritium to sustain D-T fusion (see text)? by DanTheTerrible

Oh it would allow you to breed plutonium. It would also allow you to fission some of the blanket. That might not be the best idea for your magnets behind the blanket.

You have to absorb neutron flux regardless.

This is one argument in favor of aneutronic designs, that fusion may not ever be practical if the reaction emits a significant amount of neutrons. Hydrogen-B11 for instance. I understand it's immensely harder to do though, requiring much higher temperatures.

An aneutronic design could be designed to fail if someone tries to breed plutonium.

If you're going through the trouble it'd just make more sense to go ahead and build a magnox reactor like North Korea did. Not like the plans are secret.
