I'm really surprised - the journalists in the link (and I read the sublinks too) missed the entire thing.
Sure, it's a sub-crit test. We also do non-crit tests a lot - you see them at different facilities, I recall maybe two years ago Sandia was running
some in the midwest. Generally if you hear a ruckus about Sandia or LANL "blowing up DEPLETED URANIUM!!" what you're seeing is a test of the
compression structure of a new nuke design.
In this case, (and the sub crit test in question) those hydrodynamics non-critical tests that Sandia was running on DU loads and this peanut shot were
part of a design test for Sandia's new "no maintenance" nuke design. You'll see more of that regularly over the next couple of years - Sandia won
the design contract in a contest with LANL about 5-6 years ago.
The point is to design a weapon with no tritium boost system and no tritium-containing initiation devices that need no field maintenance for years at
a time. Also, there were a lot of new technologies that had come up since the last big weapon design effort, and it makes possible a LOT of new
tricks, and those all have to be tested as well, ground up, start to finish, from new explosive lensing to the initiator technology.
