Dr. Raymond Grills was a DuPont physical chemist who worked at Chicago 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.
