Hoffman

Nuclear chemist Darleane D. Hoffman, who was renowned for her research on transuranium elements that advanced the understanding of nuclear fission, died on September 4 at her home in Menlo Park, Calif. She was 98.

Iowa origins: Hoffman was born on November 8, 1926, in Terril, Ia. She attended Iowa State University, where she earned a bachelor’s degree in chemistry in 1948 and a doctorate in physical (or nuclear) chemistry in 1951. She then began working as a chemist at Oak Ridge National Laboratory.

Los Alamos research: In 1953, Hoffman began a research position at Los Alamos National Laboratory, where she conducted pioneering work on spontaneous fission. She served as the lab’s first female division leader in charge of the Chemistry and Nuclear Chemistry Division.

Better information regarding the specific work needed to finish cleaning up contaminated soil and legacy landfills at Department of Energy nuclear sites could help the department better prioritize cleanup projects and improve budgeting decisions, according to an audit by the Government Accountability Office.

DOE awards $35M to help commercialize national lab technologies

September 5, 2025, 12:00PMNuclear News

The Department of Energy announced recently it will provide more than $35 million for 42 projects to help move emerging energy technologies from DOE national laboratories, plants, and sites related to grid security, artificial intelligence, nuclear energy, and advanced manufacturing to the marketplace. The selected projects will leverage over $21 million in cost-share from private and public partners, bringing total funding to more than $57.5 million.

A full list of the FY2025 selections is available here.
