Series of nuclear tests

series of seven nuclear weapons tests conducted by the United States in late 1951

The RDS-2 (Russian: РДС-2) was a second nuclear bomb developed by the Soviet Union as an improved version of the RDS-1. It included new explosive lenses along with a new core design to decrease the probability of pre-detonation or 'fizzle'. The levitated core increased implosion efficiency by allowing for an empty space between the "flying layer" and the core, thereby allowing rapid acceleration of the shock wave before it impacted the core.
