Nevada's Historic BREN Atomic Test Tower Demolished

Yesterday, in the Nevada desert, demolition crews from New York and Maryland felled a legendary piece of America's atomic history.

At 1,527 feet tall, the former Nevada Test Site's BREN tower was the "tallest free-standing structure west of the Mississippi River," and also the "tallest structure of its kind ever demolished," according to the National Nuclear Safety Administration. Originally built in 1962 in Yucca Flats, from fifty-one 30-foot sections of steel and two and a half miles of steel cable, the tower was moved to its latest location in Jackass Flats in 1966 after the Nuclear Test Ban Treaty banned open-air nuclear testing.

From CNN: The tower stood taller than the Empire State Building (1,454 feet) and the Eiffel Tower (1,063 feet). It was also taller than the iconic Stratosphere (1,148 feet) on the Las Vegas strip...[T]he BREN Tower took its name from the nuclear radiation experiment for which it was built: Bare Reactor Experiment - Nevada. BREN Tower was designed to provide a way for scientists to accurately estimate radiation doses received by survivors of the atomic bombs detonated over the Japanese cities of Hiroshima and Nagasaki during World War II. The tower stood 1,527 feet tall because that was the height at which "Little Boy," the first atomic bomb used in warfare, was detonated over Hiroshima on August 6, 1945.

At one time, a mock Japanese village was built near the tower's base to give researchers better modeling of the effects of a nuclear explosion on inhabited areas. Officials from the NNSA said the tower, which stopped being used in 1999, was too costly to maintain and restore, and posed a hazard to passing aircraft.

Surfing the Nuclear Web: from Australia to Argonne

Looking for more radiation related sites? There's the informative and descriptively-named Radioactive Waste blog from Australia:

Being an environmental scientist of the disorganised type, and also overwhelmed by the quantity of sites of relevance to my interest in safety of radioactive waste, my hope is that this blog will bring some order to my life (this part at least)! All views & irreverent commentary expressed here are entirely my personal opinion, of course. In Australia, after cleaning up the mess at Maralinga (former UK nuclear weapons test site), we are now in process of building a national radwaste repository.

Jef's Web Files has a section focusing on nuclear safety, with recent posts about the development of detectors that can "smell" nukes, and the U.S. government's recent revival of a lost Cold War art - fallout analysis.

Atom Central is an intriguing portal with sections on the atom bomb, the Trinity site and video releases on Hiroshima and Nagasaki, American bomb tests and more.

Of special interest is the Argonne National Laboratory's engineering research website:

Argonne's rich heritage in the development of nuclear reactors began with CP-1, the world's first nuclear reactor brought to life by Enrico Fermi and his team on December 2, 1942, under the West stands at Stagg Field on the campus of the University of Chicago.

Dr. Walter H. Zinn, one of Fermi's close colleagues working on CP-1, became Argonne National Laboratory's first director in July 1946. In 1948, the United States Atomic Energy Commission (AEC) transferred the major portion of the nation's nuclear reactor development program to Argonne. Under Dr. Zinn's vision and leadership, Argonne established a vigorous and far-reaching program to develop nuclear reactors of virtually all types.

You can see some of Argonne's history in video: Argonne's pioneering nuclear research is prominently featured in the documentary Atoms for Peace (1994, VHS), hosted by Bill Kurtis (whom we met as the host of the program NOVA: Back to Chernobyl). This one-hour feature details the history of the American peacetime nuclear program with its focus on energy production (and the U.S. fast-breeder reactor program, now on indefinite hiatus), as well as its linkage back to the early weapons development initiatives at Oak Ridge National Laboratory in Tennessee, Arco, Idaho (the first town to be powered by nuclear energy) and the now-defunct Hanford site power plant in Washington state. While Atoms for Peace is a bit hard to track down, you'll probably be able to find a copy at larger public libraries with video collections.
