As a tour guide for the Manhattan Project National Historical Park Hanford; Branch B Reactor–Headquarters in Richland, Washington, Im thrilled to share its fascinating history with you. This place is not just a regular park, but a monument that tells the story of an era when science and engineering took the world by storm with the creation of nuclear weapons during World War II.

Imagine, if you will, a time when the entire world was in turmoil, fighting a war on multiple fronts. The United States, determined to put an end to this devastating conflict, embarked on a top-secret project that would change history forever – the Manhattan Project. This ambitious undertaking led to the development of the worlds first full-scale plutonium production reactor: the B Reactor, which stands right here in front of you today.

Constructed by the DuPont Corporation under contract with the U.S. government, this colossal machine was built in record time during the height of World War II. It served as a critical component in producing plutonium for nuclear weapons, such as the Fat Man bomb used in Nagasaki, Japan. The B Reactor played a pivotal role in ensuring the safety and freedom of the world, making it a truly remarkable historical site.

As you walk through this vast complex, youll get a sense of the immense scale and importance of the work conducted here. The Hanford site spans an incredible 580 square miles of semi-arid desert in southeast Washington, encompassing several facilities related to the Manhattan Project. Today, these areas are maintained by the U.S. Department of Energy and opened up for public tours, giving you a unique opportunity to learn about this fascinating chapter in human history.

Standing before the imposing structure of the B Reactor, its difficult not to be captivated by its sheer size and complexity. This marvel of engineering, completed in 1943, housed countless valves, pipes, and control panels, all operated by skilled workers who tirelessly worked to ensure that plutonium production proceeded smoothly.

The B Reactors legacy lives on through the stories of the people who designed, built, and operated it – many of whom were pioneers in their field, pushing the boundaries of science and technology to achieve a seemingly impossible goal. Their dedication, hard work, and ingenuity have left an indelible mark on history, one that can still be felt and seen at this remarkable site today.

So, as you wander through the hallowed halls of the B Reactor, take a moment to appreciate the incredible achievements of those who came before us. Their work here transformed the course of human history, shaping the world we live in today. And now, as you continue your tour, I hope youll carry with you not only an understanding of this crucial historical site but also a sense of wonder and appreciation for the remarkable people whose efforts brought it to life.
