Biography

Allen Croff is an Adjunct Professor of Nuclear Environmental Engineering in the Department of Civil and Environmental Engineering at Vanderbilt University. He is also a member of the U.S. Nuclear Waste Technical Review Board, appointed to this position by the President in February 2015, and a Distinguished Emeritus Member of the National Council on Radiation Protection and Measurements.

Allen Croff brings to Vanderbilt 29 years of technical and program management experience in positions of increasing responsibility at Oak Ridge National Laboratory. He was subsequently vice-chairman of the Advisory Committee on Nuclear Waste in the U.S. Nuclear Regulatory Commission and a Senior Technical Advisor to the Blue Ribbon Commission on America’s Nuclear Future. He has led or participated in numerous multi-disciplinary national and international technical and review committees for the National Academy of Sciences, the National Council on Radiation Protection and Management, the Nuclear Energy Research Advisory Committee, and the Nuclear Development Committee of the Nuclear Energy Agency.

Allen Croff’s technical accomplishments include creation of the ORIGEN2 computer code used world-wide to calculate the radioactive characteristics of nuclear materials for use in nuclear material and waste characterization, risk analyses, and nuclear fuel cycle analysis; developing and evaluating comprehensive, risk-based waste classification systems, including changing the boundary defining transuranic waste from 10 to 100 nCi/g; technical, economic, and systems analysis of current and advanced nuclear fuel/material cycles from uranium mining through waste disposal; conceiving, analyzing, and reviewing actinide partitioning-transmutation (P-T) concepts beginning with the first comprehensive analysis of P-T from 1976 to 1980 through subsequent cycles of renewed interest in the concept up to the present.
