This 1954 radio program traces the development of nuclear energy from the discovery of the atomic nucleus to the launch of the USS “Nautilus,” the first nuclear submarine. It includes narration, dramatizations with actors playing physicists Ernest Rutherford and Niels Bohr, and interviews with Arthur H. Compton and Westinghouse Electric Corporation scientists. The program celebrates Westinghouse’s role in producing uranium for the Manhattan Project and details the challenges behind powering the Nautilus.
Dr. Raymond Grills was a DuPont physical chemist who worked at the University of Chicago Met Lab and later at Hanford during the Manhattan Project. While at Hanford, he was one of two men who invented the canning process that sealed uranium slugs for use in Hanford’s water-cooled nuclear reactors. In this interview, he describes the challenges and pressures he and his colleagues had to overcome, and explains why the canning had to be designed perfectly. He also describes humorous encounters with a machinist and a railroad porter while transporting uranium slugs.
Dr. Clarence Larson, a chemist, began working under Ernest O. Lawrence in his lab at the University of California, Berkeley in 1942. In 1943, he moved to Oak Ridge and was appointed head of technical staff for the Tennessee Eastman Corporation. He later served as director of Oak Ridge National Laboratory and as a commissioner on the U.S. Atomic Energy Commission. During the Manhattan Project, Larson designed a process to recover and purify uranium deposits from the walls of calutron receivers at the Y-12 Plant. In this interview, he explains the importance of this innovation in producing enough enriched uranium for an atomic bomb. He also describes the challenges encountered in the Y-12 Plant’s early days, as well as Lawrence’s leadership skills and unyielding confidence.
J.C. Hobbs was an American inventor and engineer who created a key part of the valves used in the K-25 gaseous diffusion plant in Oak Ridge, Tennessee. Hobbs was brought on to the Manhattan Project by the head of the Kellex Corporation, Percival Keith, to improve the piping system in the K-25 plant. In part three of his interview with Stephane Groueff, Hobbs discusses the key role he played in troubleshooting problems for K-25 and for other power plants across the country. He emphasizes the importance of the efficiencies he introduced at K-25, and describes some of the technical challenges he and his colleagues faced.
Harry Allen and Robert Van Gemert worked in procurement at Los Alamos during the Manhattan Project. In this interview, the pair discusses getting ready for the Trinity test, the challenges of using Jumbo, and how materials were transported safely and secretly in and out of Los Alamos. They remember helping to acquire the lead-lined tanks used to transport scientists to the blast zone after the Trinity test. Allen and Van Gemert also discuss the dormitories at Los Alamos, how the Town Council handled problems, and the secrets of PO Box 1663. They recall their interactions with leading scientists including Emilio Segre, Enrico Fermi, and Edward Teller.
General Kenneth Nichols was the District Engineer for the Manhattan Engineering District, and oversaw the design and operation of the Hanford and Oak Ridge sites. He was responsible for securing the initial deals with Stone & Webster and the DuPont Company to develop the industry for the site, and lived for a time with his wife at Oak Ridge. He discusses sabotage and Klaus Fuchs, dealings with the British, and the very start of the Manhattan Project. He recalls some conflict between the scientists and engineers, the importance of industry in the project, and the initial problems with the startup of the B Reactor.
Colonel Franklin Matthias was the officer-in-charge at the Hanford site. In the second part of his interview with Stephane Groueff, Matthias describes the personalities of the men he worked with, including Enrico Fermi and DuPont’s Granville Read. He recalls a visit by Fermi and Eugene Wigner to Hanford, and explains why Read got along well with General Leslie Groves. Matthias discusses the safety measures at Hanford, and recounts how a Japanese fire balloon temporarily knocked out power to the plant. He also explains how scientists conducted tests on salmon to assess levels of radioactive contamination in the Columbia River.
Newton Stapleton worked for the legal department at DuPont when he was recruited to work on the Manhattan Project. He became responsible for security and secrecy at Hanford, WA. He describes the security procedures in place, including how background checks were conducted and badges were issued. He discusses the emphasis on secrecy and how DuPont’s leaders urged workers to keep quiet about their work. Stapleton recalls the challenge of getting a four-bedroom home in Richland and bringing his family out to Richland.
J.C. Hobbs was an American inventor and engineer who created a key part of the valves used in the K-25 gaseous diffusion plant in Oak Ridge, Tennessee. Hobbs was brought on to the Manhattan Project by the head of the Kellex Corporation, Percival Keith, to improve the piping system in the K-25 plant. In this interview, Hobbs discusses his career in industrial engineering, the work environment in New York, and the development of the valves that proved crucial to the success of gaseous diffusion.
Colonel Franklin Matthias was the officer-in-charge at the Hanford site. In this interview, Matthias discusses his early life and his placement as the officer-in-charge at Hanford. He also talks about the relationships between DuPont and the military and the scientists, as well as how cooperation was essential. Matthias remembers the various problems that plagued the Hanford site and how he and his colleagues overcame them.
