===MET===

The ''MET'' was the first bomb core to include [[uranium-233]] (a rarely used [[fissile isotope]] that is the product of [[thorium-232]] neutron absorption), [[Pit (nuclear weapon)#Composite cores and uranium pits|along with plutonium]]; this was based on the plutonium/U-235 pit from the TX-7E, a prototype [[Mark 7 nuclear bomb]] design used in the 1951 ''[[Operation Buster-Jangle]] Easy'' test. It produced a yield of 22kt (comparable to the ''[[Fat Man]]'' plutonium-only weapon that exploded over Nagasaki), but significantly less than the expected amount. Since it was a military effects test, the DoD specified that the device should have a calibrated yield within 10% of ratings. However, weapon designers at Los Alamos substituted the experimental core without notifying the DoD. The unexpected lower yield, 33% less than the DoD expected, ruined many of the military's tests.<ref>{{cite web | url= http://nuclearweaponarchive.org/Usa/Tests/Teapot.html | title= Operation Teapot |date= October 15, 1997 | work= Nuclear Weapon Archive | access-date= December 9, 2008 }} "The predicted yield was 33 kt. The actual 22 kt was 33% below this, seriously compromising the data collected."
