I only now happened to run across the article below from the Los Alamos National Laboratory Nuclear Weapons Journal about how the remanufacturing of Fogbank was reestablished. As dated as it is, I think its implication is very important that existing programs are more than sufficient to keep the nuclear weapons stockpile safe and reliable, until eventual disarmament.
You may recall that the loss of Fogbank was a bit of a crisis that seriously delayed the W76 Life Extension Program. It had at various times been used as rationale for why existing LEPs would not work in the long run because of necessary changes to materials, loss of knowledgeable workforce, etc. By extension this was used to argue why Reliable Replacement Warheads should be designed and built.
But this article demonstrates that all that was needed was to simply give some emphasis to reestablishing fogbank production. Plus as an added bonus, it has some pleasing wonky detail. “It’s the impurity, stupid!” [see link below]
