“Bunker Busters”: Robust Nuclear Earth Penetrator
Issues, FY2005-FY2007
Summary
Earth penetrator weapons, often called “bunker busters,” burrow into the ground
some tens of feet before detonating, greatly increasing their ability to destroy buried
targets. The United States has several types of conventional earth penetrators. The
current U.S. nuclear earth penetrator, the B61-11 bomb, cannot penetrate certain
types of terrain in which hardened underground facilities may be located, so the Air
Force and the National Nuclear Security Administration (NNSA) are studying a more
effective penetrator, the Robust Nuclear Earth Penetrator (RNEP).
The United States has one type of nuclear earth penetrator, the B61-11 bomb,
which was accepted into the stockpile in September 2001.1
To address some technical issues that have arisen in the RNEP debates, the Bob
Stump National Defense Authorization Act for FY2003, P.L. 107-314, Section 1033,
called for a National Academy of Sciences report on effects of nuclear and
conventional earth penetrator weapons (EPWs). The report, released in April 2005,
had nine key conclusions: (1) many high-value buried facilities can be held at risk by
nuclear but not conventional EPWs; (2) penetration to a depth of 3 meters captures
most effects of EPWs on buried targets; deeper penetration puts the weapon at greater
risk; (3) EPWs cannot penetrate deeply enough to contain nuclear weapon effects
fully; (4) casualties from a nuclear weapon burst at shallow depth or on the surface
are essentially the same; (5) detonating a nuclear weapon at shallow depth increases
the energy transmitted to a buried target, permitting a reduction in yield by a factor
of 15 to 25; (6) attacks using nuclear EPWs near urban areas could produce
thousands to over a million casualties, or hundreds to several hundred thousand for
attacks in rural areas; (7) a nuclear EPW could reduce civilian casualties in an urban
area by a factor of 2 to 10 compared to a surface-burst weapon with 25 times the
yield; (8) a nuclear weapon would have to detonate within a chamber where chemical
or biological agents were stored to destroy the agents; the same is true of nonnuclear
“thermobaric” bombs, which generate high heat and pressure; and (9) in a nuclear
attack on a chemical weapon facility, nuclear effects would probably kill many more
civilians than would the released chemical agent, while a nuclear attack on a biological facility could kill similar numbers of civilians from nuclear effects and released biological agents, depending on weapon yield and amount of agent.5
attacks using nuclear EPWs near urban areas could produce
thousands to over a million casualties, or hundreds to several hundred thousand for
attacks in rural areas

THIS IS THE SMOKING GUN - This is the very Nuclear Weapon that was "accepted into the stockpile in September 2001"...

This is not a surprise, depleted uranium weaponry is "atomic" in nature, and we know about that.

Yeah but I could say that about anything literally.
All objects in the Universe are "atomic" in nature, essentially. Even the ice cream I am about to eat, is atomic in it's nature.
Sorry to nitpick, just showing the misunderstanding in your statement.
