A 16-university team of 31 scientists and engineers, under the title Consortium for Nuclear Forensics and led by the University of Florida, has been selected by the Department of Energy’s National Nuclear Security Administration (NNSA) to develop the next generation of new technologies and insights in nuclear forensics.

CP-1 at 80: The events of December 2, 1942

December 1, 2022, 12:01PMNuclear News

On the eve of the 80th anniversary of the first controlled nuclear chain reaction, Nuclear Newswire is back with the second of three prepared #ThrowbackThursday posts of CP-1 coverage from past issues of Nuclear News.

On November 17, we surveyed the events of 1942 leading up to the construction of Chicago Pile-1, an assemblage of graphite bricks and uranium “pseudospheres” used to achieve and control a self-sustaining fission reaction on December 2, 1942, inside a squash court at the University of Chicago’s Stagg Field.

Today we’ll pick up where we left off, as construction of CP-1 began on November 16, 1942.

CP-1 at 80: Preparing for the first controlled nuclear chain reaction

As we approach the 80th anniversary of controlled nuclear fission, Nuclear Newswire is prepared to deliver not one but three #ThrowbackThursday posts of CP-1 highlights unearthed from past issues of Nuclear News.

ANS was founded in 1954, nearly 12 years after the first controlled nuclear chain reaction was achieved on December 2, 1942, inside a pile of graphite and uranium assembled on a squash court at the University of Chicago’s Stagg Field. By 1962, ANS was prepared to “salute the 20th anniversary of the first chain reaction” at their Winter Meeting, displaying a model of Chicago Pile-1 and presenting a specially cast medal to Walter Zinn, a representative of Enrico Fermi’s scientific team. Over the years, ANS has continued to mark significant anniversaries of CP-1 at national meetings and in NN.

The Mother of Radiation: Marie Curie

November 7, 2018, 7:57AMANS Nuclear CafeKaitlyn Butler

Marie CurieThe start of Marie Curie's story isn't like most of the other scientists that  had made a name for themselves throughout history, mostly because she was a grown woman by the start of the 20th century. But she was the first woman to do a lot of things, including getting a Ph.D. from a university in France, and winning a Nobel Prize. She was also the first person ever to win a Nobel Prize in two different fields of science. To say she pushed the societal and scientific boundaries of her era is an understatement.

Friday Nuclear Matinee: E=mc² is incomplete (!)

November 2, 2012, 6:00AMANS Nuclear Cafe

Albert Einstein's famous equation E=mc² explains, of course, why a nuclear power reactor can generate so much electricity in such a relatively tiny space, while using such a relatively tiny amount of fuel. Electricity from other forms of energy, say tidal or wind motion, sunlight, chemical bonds (burning things)... well, nuclear fission and fusion, thanks to E=mc², are definitely in their very own league.

Nuclear Matinee: Alphas and Neutrons Meet the Atomic Nucleus

May 4, 2012, 6:00AMANS Nuclear Cafe

Decades of nuclear science in just two minutes! This dramatic video takes the viewer inside the world of atomic particles, describing a rather important difference between the encounters of alpha particles and neutrons when scientists direct them at heavy atomic nuclei. The scientist referred to in the video is Leo Szilard, who conceived the possibility of a nuclear "chain reaction" among many other important scientific achievements. This nuclear chain reaction is quite a ride- so enjoy!

4th Annual Texas Atomic Film Festival

April 26, 2012, 6:00AMANS Nuclear Cafe

The 4th annual Texas Atomic Film Festival (TAFF) is being held April 26 to May 3, 2012. The festival attracts short films (3 to 5 minutes) produced by students in nuclear engineering courses at the University of Texas at Austin. A public screening of the films, which focus on nuclear and energy related topics, is being held on April 26 at 12:30 pm at the UT Student Activities Center auditorium.

Kallie Metzger: Nuclear Inspiration

March 14, 2012, 6:00AMANS Nuclear CafeSuzy Hobbs Baker

At a recent conference I had the pleasure of meeting Kallie Metzger, a young nuclear engineering Ph.D. candidate from the University of South Carolina. Kallie and I quickly discovered that we have a great deal in common, especially when it comes to our shared passion for art and science. Kallie was kind enough to share her undergraduate thesis with me, and I found it to be so unique and contemporary that I had to share it here. In her own words, here is the inspiration of a young physics student who chose to express her passion for science through art.

Lise Meitner's fantastic explanation: nuclear fission

February 14, 2012, 7:00AMANS Nuclear CafePaul Bowersox

On February 11, 1939, a Letter to the Editor titled "Disintegration of Uranium by Neutrons: a New Type of Nuclear Reaction" appeared in the science journal Nature. The letter provided the first theoretical explanation for the splitting of the atom, and coined a new term in physics: fission. The woman who co-authored the letter, and co-discovered the power of nuclear energy, is perhaps not quite as well-known as some of her contemporaries. Elise Meitner-how could hers not be a household name?

ANS to hold teacher workshop in Phoenix, AZ

ANS November 2011 Teachers Workshop

Hands-on activity during a November 2011 ANS Teachers Workshop

The American Nuclear Society's Center for Nuclear Science and Technology Information and the ANS Outreach Department will be sponsoring a one-day teacher workshop on Sunday, February 26, in Phoenix, Ariz. The workshop-Detecting Radiation in Our Radioactive World-is intended for science educators (including biology, chemistry, earth science, physics, physical science, life science, environmental, and general science teachers) at the high school and middle school levels. The workshop will be held prior to WM2012, the international waste management conference that takes place annually in Phoenix.
