Nuclear weapons using U-235 are somewhat easier to make than the plutonium designs which rely on a tricky implosion to start their nuclear chain reaction. The "Little Boy" bomb dropped on Hiroshima was an untested uranium device using a gun barrel design. Scientists at Los Alamos were confident enough the design would work that the bomb was shipped to the Pacific untested.

The plutonium implosion bomb design used in the "Fat Man" bomb dropped on Nagasaki was tested Alamagordo, New Mexico in July 1945. There was enough concern about whether this bomb would work that a large steel containment vessel was made to encapsulate the bomb and recover the precious plutonium if the bomb fizzled. The contain vessel however was not used in the test.

Lets do the time warp again!

I'm assuming this was supposed to refer to one of the ones that went bang last year.

Do we have any assurance that the upcoming nuke test in North Korea isn’t really an IRANIAN nuke?

The Iranians couldn’t test-fire their long-anticipated device anywhere on Earth without getting caught, then all hell would be unleashed. Well, no place on Earth would be safe for them except for a tunnel in a North Korean hillside ...
