Clarice Evone Phelps () is an American nuclear chemist researching the processing of radioactive transuranic elements at the US Department of Energy's Oak Ridge National Laboratory (ORNL). She was part of ORNL's team that collaborated with the Joint Institute for Nuclear Research to discover tennessine (element 117). The International Union of Pure and Applied Chemistry (IUPAC) recognizes her as the first African-American woman to be involved with the discovery of a chemical element. Phelps was formerly in the US Navy Nuclear Power Program. At ORNL, Phelps manages programs in the Department of Energy's Isotope & Fuel Cycle Technology Division investigating industrial uses of nickel-63 and

Early life and education

Clarice Phelps was raised in the state of Tennessee, United States. Her interest in chemistry began during her childhood when she was given a microscope and encyclopedia-based science kit by her mother. Her interest was further nurtured by her secondary school science teachers. She is an alumna of the Tennessee Aquatic Project and Development Group, a nonprofit organization for at-risk youth. Phelps completed a Bachelor of Science degree in chemistry from Tennessee State University in 2003. From 2016 to 2020, Phelps earned a M.S. in Mechanical Engineering through the nuclear and radiochemistry program at the University of Texas at Austin. , Phelps is a Ph.D. student in the nuclear engineering program at University of Tennessee.


Career


United States Navy

Phelps struggled academically in college. Unable to find employment after graduating, she joined the United States Navy. Phelps enrolled in the Navy's Nuclear Power School, 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

in the United States Navy Nuclear Power Program. She spent four and a half years aboard the aircraft carrier , operating the nuclear reactor and steam generator chemistry controls, and maintaining the water in the reactor. She was deployed twice, and was the only black woman in her division on the ship.


Oak Ridge National Laboratory

After serving in the US Navy, Phelps worked at chemical instrument company Cole-Parmer in Chicago, Illinois, but a year later, not liking the cold Chicago climate, she returned to Tennessee. In June 2009, Phelps joined Oak Ridge National Laboratory. She started as a technician and was later promoted to research associate and program manager. Phelps works in the Nuclear Science and Engineering Directorate as the project manager for the nickel-63 and

, which was shipped to the Joint Institute for Nuclear Research and combined with calcium-48 in a fusion reaction to create tennessine. 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 chemical element. 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 spectroscopic analysis and

Phelps is also the Vice President of the board of Youth Outreach in Science, Technology, Engineering and Mathematics (YO-STEM). Phelps was featured on the Oak Ridge Associated Universities STEM stories program, partnering with nearby schools in Tennessee. Phelps received the 2017 YWCA Knoxville Tribute to Women Award in the category Technology, Research, and Innovation. This award recognizes "local women who lead their fields in technology and excel in community service". In 2019, the International Union of Pure and Applied Chemistry (IUPAC) featured Phelps in the Periodic Table of Younger Chemists in recognition of "her outstanding commitment to research and public engagement, as well as being an important advocate for diversity". She was one of two Oak Ridge National Laboratory researchers thus honored. Phelps is associated on this honorary periodic table with the element einsteinium, having along with others, including

'', "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.
