Trump’s press conference in Singapore where he tells us about the scientific fifteen year time period it takes to denuclearize — WTF? I’ve got all the respect in the world for PoliSci studies, but it’s not *scientifically* required that “you have to wait certain periods of time, and a lot of things happen”. Unless we’re talking about complete decay of the fissionable material – in which case fifteen years is WAAAAAY short. The half-life of U-235 is like 700 million years.
Blending it down to reactor-grade, though – NNSA contracts have down-blended well over a tonne of HEU a year. The problem is 1 tonne of HEU becomes 16 tonnes of LEU. And how many reactors, submarines, and space vehicles do we need to fuel? Doubtful NK’s got facilities for down-blending weapon-grade material, but “de-enrich my stuff at your facility for free and I won’t have nukes” would be a really strong negotiating position — and as much as Trump may decry billions Clinton spent to denuclearize NK … it would be billions well spent if there were no enriched material in the country. And NK has maybe half a tonne of HEU – the logistics of shipping the shit would take longer than down-blending it.
But we’ve got a president looking at what may be a reasonable political estimate of how long it would take the country to denuclearize and calling it a scientific requirement. Which is ironic given the number of *actual* scientific things the administration feels free to ignore.
