B Reactor Begins Plutonium Production
On November 6, 1944, the B Reactor at the Hanford Site in Washington State commenced plutonium production. This marked a significant milestone in nuclear history, as the B Reactor became the world's first large-scale plutonium production reactor. The plutonium generated here played a crucial role in developing atomic bombs during World War II, fundamentally altering the landscape of warfare and international relations. This achievement not only showcased the advancements in nuclear technology but also highlighted the importance of scientific collaboration during a pivotal time in history.
Fun fact. The B Reactor produced enough plutonium for the bomb dropped on Nagasaki.
