I’m skeeptical. The article states that HEU is not terribly hot- which is true for DU, but 20% U235 is quite a bit hotter. Chances are that this is DU.

If it’s not, the main use for HEU in small quantities is for cross-section research. You are not going to make a nuclear explosive with 20% enriched material.

Light water nuclear reactors have fuel rods that are only 4% enriched with U235.

The amount of U235 in depleted uranium is about 0.2 to 0.3 weight-percent. So something that is 20% U235 is five times (500% ) hotter than fuel rods and 100 times (10,000%) hotter than depleted uranium. And when you consider that 0.2 weight-percent U235 in depleted uranium is about 30% of what it was in its naturally occurring form, something that is 20% U235 is highly enriched.
