Mmm, I was looking at the Uranium 235 Spike Nitrate solution, a few rows further up – 99.8% U235 .
The sample is listed as 0.1g U (presumably this is just the U, without the No3 bit) so, as you’d need about 14kg as a critical mass in a really well-designed warhead, the fissile material bill comes to $292,600,000.
Superpower status clearly doesn’t come cheap – although the price is coming down…
Ooo – just saw the “93% U235, 0.5-4kg U” bit in brackets, on the item you ringed. Superpowerdom is clearly *much* cheaper than it used to be (and I need more caffeine).
