, which she credits with teaching her "how to study". Phelps studied nuclear power, reactor theory, and thermodynamics, and graduated in the top 10% of her class of 300–400 students. In 2019, Phelps told an interviewer that she pursued nuclear chemistry in part because of the lack of black women in the field, commenting: "They needed to see somebody like me sitting in the same spaces that they were at, and excelling in that same space." Phelps served as a non-commissioned officer in the

As a member of Oak Ridge's Nuclear Materials Processing Group, she is part of the research and development staff, working with "super heavy" transuranic isotopes that are produced mainly by nuclear transmutation. She is also a member of the Medical, Industrial and Research Isotopes Group, where she researches elements such as

In IUPAC's crediting Oak Ridge laboratory collectively as principal co-discoverer of tennessine, it acknowledged 61 individuals at ORNL who had contributed to the project including members of operations staff, support personnel, and researchers such as Phelps. It recognized Phelps as the first African-American woman involved with the discovery of a

. When Oak Ridge National Laboratory held a gala to honor and celebrate the team that discovered tennessine, Phelps's name was left off the list, and when she showed up, she cried as she realized that she did not have a seat at the table with the other scientists. In addition, a plaque to commemorate the discovery was created to be hung up in perpetuity at the laboratory, and once again, it omitted her name. Phelps was told that her name had been cut off by mistake due to a line break in a spreadsheet. While the laboratory later claimed that the "error asquickly corrected", it was only after Phelps fought for several months to have her name included that the laboratory acquiesced. Phelps has contributed to additional research efforts, including those of

'' published an op-ed about, in part, the English-language Wikipedia's lack of coverage given to Phelps' contribution to the discovery of element 117. The column, co-written by Wade, decried discussions among volunteer editors at the site that resulted in deletion of the article on Phelps. According to an article in the July 2019 '' Chemistry World'', "her name didn't appear in the articles announcing tennessine's discovery. She wasn't profiled by mainstream media. Most mentions of her work are on her employer's website – a source that's not classed as independent by Wikipedia standards and therefore not admissible when it comes to establishing notability. The ikipediacommunity consensus was that her biography had to go." The deletion was contested multiple times. By January 2020, there was a consensus to restore it, as by then new sources had become available.
