From the AP: The last of the nation’s most powerful nuclear bombs — a weapon hundreds of times stronger than the bomb dropped on Hiroshima — is being disassembled nearly half a century after it was put into service at the height of the Cold War.
The final components of the B53 bomb will be broken down Tuesday at the Pantex Plant near Amarillo, the nation’s only nuclear weapons assembly and disassembly facility. The completion of the dismantling program is a year ahead of schedule, according to the U.S. Department of Energy’s National Nuclear Security Administration, and aligns with President Barack Obama’s goal of reducing the number of nuclear weapons. . . .
The B53 was designed to destroy facilities deep underground, and it was carried by B-52 bombers. . . .
The weapon is considered dismantled when the roughly 300 pounds of high explosives inside are separated from the special nuclear material, known as the pit. The uranium pits from bombs dismantled at Pantex will be stored on an interim basis at the plant, [Pantex spokesman Greg] Cunningham said.
The material and components are then processed, which includes sanitizing, recycling and disposal, the National Nuclear Security Administration said last fall when it announced the Texas plant’s role in the B53 dismantling. (photo: National Nuclear Security Administration/AP)
