This sustained, uncontrolled reaction by itself can be rather destructive: the atomic bomb that was dropped on the Japanese city of Nagasaki in World War II used this plutonium implosion and subsequent chain reaction to produce a blast wave, heat, and radiation that devastated a good proportion of the city. It's estimated that Fat Man bomb exploded with the equivalent force of about 21,000 tons of TNT.
Uncle Sam argues these kinds of experiments are not a violation of its promise to not conduct overground and underground nuclear weapons tests. "If you had a car in a garage for 30 to 50 years, and one day you insert the ignition key, how confident are you that it will start," Sandia National Lab's Jon CusterThe agency largely relies on massive supercomputers to run its nuclear simulations in software, providing insight into how weapon components will perform in the fractions of a second after a device is set off. This is what the newly inaugurated Crossroads super welast month is tasked with.
It's a capability Custer said"really puts the computer codes to the test." By computer codes, he means: the simulation software on the supers.
