Darleane C. Hoffman, transuranium element pioneer, dies at age 98
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.

The purpose of the ALPS program is to identify and evaluate advanced limiter/divertor systems that will enhance the attractiveness of fusion power. The highest priority goals at present are achieving high power density, up to 50 MW/m2, and showing compatibility of plasma-facing surfaces with plasma operation. Personnel representing a wide range of disciplines from a number of institutions are engaged in the program, where an evaluation phase of the program is planned for three years. Successful identification of promising concepts in the evaluation phase should lead to an R&D phase that includes proof-of-principle experiments.
