The Tsar Bomba. It was tested in 1961 by the USSR on the island of Novaya Zemlya within the Arctic Circle. Its design yield was 100 megatons, but the yield was reduced to 57 megatons for the test by replacing the uranium-238 third stage tamper with a different metal (e.g. lead, tungsten) that would not fission when hit by the high energy fusion neutrons (and thus would not contribute to the yield or the fallout).The Tsar Bomba was not only the highest yield nuclear bomb ever tested, it was the highest yield nuclear bomb actually dropped from a bomber airplane. The Tsar Bomba also turned out to be the cleanest nuclear explosion with only about 3% fission yield and a correspondingly small amount of fallout relative to its total yield. Nuclear explosions having 5% or less fission yield are usually called "clean".
If by strongest you mean highest yield, I believe this would be Russia. Current treaties allow them higher yield weapons because their ICBMs are somewhat less accurate than US ICBMs.
He designed several Soviet nuclear weapons, including the Tsar Bomba, the highest yield device ever tested. Later he became an important member of the antinuclear weapons movement in the USSR, which got him imprisoned.

Washington Mutual currently offers the highest yield CD. You can find the most updated rates at www.Bankrate.com/NewYork_CD_Rates or www.bankrate.com/cd.aspx
High(est) energy yield,less polusion
The longer the maturity cycle, generally the higher the yield. A three to five year cd will get the highest yield right now.
Depends on yield and height/depth of burst.
energy release aka yield
The nuclear bomb A MK-3 Plutonium implosion bomb, it weighed 10,000 pounds and had a 22Kton yield.
