  1. I wonder how low a concentration of Pu-240 you would need to get to before the material would become useable in a reasonably-sized gun design...

  2. Interestingly, Pu-238 apparently actually has a lower critical mass than Pu-239, the lowest of any plutonium isotope. (Which is kinda weird, given that the other even-mass plutonium isotopes have much greater critical masses than Pu-239, Pu-241, and Pu-243.)

  3. 10:50 - Don't weapons-fabrication facilities pretty much all use those techniques already (to reduce worker-safety risks in the event of a criticality accident)?
