That's an interesting mistake. Fusion reactor designs today mostly target deuterium-tritium fuel, because it's the most energetic and easiest to get net power.

That's an interesting mistake. Fusion reactor designs today mostly target deuterium-tritium fuel, because it's the most energetic and easiest to get net power. They plan to breed the tritium from a blanket of lithium. Based on this article, it sounds like the bomb scientists were using lithium deuteride fuel just as a solid form of deuterium, and didn't realize the lithium would breed tritium and fuel a more powerful reaction. Now I'm wondering whether this unfortunate event was the seed for today's reactor designs.
