“We want no enrichment, but we also want the enriched uranium,” he told CNN’s Kaitlan Collins last week. But nuclear arms experts say the way Trump and his lead negotiator have talked about uranium enrichment raises doubts about how well they understand the technicalities. Commercial reactors typically require uranium enriched to less than 5%, while research reactors used for testing or medicine generally require uranium enriched to up to 20%. Uranium enriched beyond 20% is considered highly enriched uranium, and uranium enriched above 90% is considered weapons-grade. Uranium enriched to weapons-grade requires about 28 kilograms, which can fit into a missile warhead, he says.
