Work crews at the Department of Energy’s Savannah River Site in South Carolina recently replaced a motor on a crane in the 70-year-old H Canyon Chemical Separations Facility. H Canyon is the only production-scale, radiologically shielded chemical separations plant in operation in the United States.

The Hanford B Reactor

In remote southeastern Washington you will find the sprawling Hanford Site, which was constructed to produce plutonium for the Manhattan Project. Within this complex is the first plutonium production reactor, the Hanford B Reactor. The DuPont Corporation was responsible for construction and operation of the B Reactor. Due to the urgency of the Manhattan Project, construction was completed in just over a year, and The B Reactor went critical on September 26, 1944. After the needs of the Manhattan Project were satisfied, the reactor was briefly shut down and then restarted to produce plutonium for roughly another 20 years, supporting Cold War efforts. In addition to plutonium production, the B Reactor also pioneered the process to produce tritium for the first-ever thermonuclear test.

The male business of nuclear diplomacy

An unusual event during the recent General Conference of the International Atomic Energy Agency distracted the delegations of member states and the press from the Russian war in Ukraine and the fear of the next nuclear disaster. It was a small exhibition, Building the IAEA Headquarters and its Laboratories, at the IAEA headquarters in Vienna, which brought to life the history of the agency’s laboratories through photographs, original letters and documents, explanatory texts, and timetables.

I was invited to participate in a related panel discussion that shed light on the early days of the “world’s first full-fledged laboratory of a truly international character” (in the words of an article about Seibersdorf Laboratory that ran in the January 1962 edition of the IAEA Bulletin) and its role in science diplomacy. There, I spoke of something that had struck me: Women were totally missing from the agency during this early period—making nuclear diplomacy an exclusively male business. To a large extent (as, for example, the recent IAEA missions to Ukraine show) nuclear continues to be a gendered endeavor.

George P. Shultz, a former U.S. secretary of state who played a central role in helping bring the Cold War to an end, died Saturday at 100, the Hoover Institution at Stanford University announced.

ANS connection: Shultz, an ANS member, was honored during the 2020 ANS Virtual Winter Meeting with a celebration of his 100th birthday. He provided recorded comments on the increasing challenges facing policy decisions related to climate change, artificial intelligence, and advanced manufacturing/3D printing. Former senator Sam Nunn reviewed Shultz’s “500 years' worth” of accomplishments and service to the United States.

ANS has issued a statement on the passing of George Schultz.
