David G. Huizenga

Principal Assistant Deputy Administrator for Defense Nuclear Nonproliferation

David Huizenga is a recognized expert in nonproliferation and nuclear waste management issues, with decades of leadership, management, and technical experience in a wide variety of programs across the Department of Energy (DOE). He currently serves as the Principal Assistant Deputy Administrator for Defense Nuclear Nonproliferation (DNN) at NNSA. In this role,  Huizenga manages DNN’s mission to detect, secure, and dispose of dangerous nuclear and radiological material, and related WMD technology and expertise. DNN looks to reduce global nuclear dangers by advancing capabilities to prevent nuclear and radiological proliferation and terrorism threats worldwide by working closely with its domestic and international partners, the U.S. National Laboratories and other Federal agencies.

Prior to his current assignment, Huizenga served as the acting Assistant Secretary for the Office of Environmental Management (EM). In this capacity, he was responsible for the management and oversight of the world’s largest environmental remediation program. Huizenga worked closely with state and local governments and stakeholders to drive effective assistance cleanup activities at the 17 EM cleanup sites across the nation. Under Huizenga’s leadership, EM commenced a major re-planning initiative to update the EM baseline and prioritize cleanup activities.

Earlier, Huizenga served as NNSA’s Assistant Deputy Administrator for the Office of International Material Protection and Cooperation, where he managed several key national security programs aimed at reducing the worldwide threat of nuclear terrorism by working cooperatively with more than 100 countries to secure nuclear weapons and weapons-usable nuclear materials and enhance the detection of illicit trafficking of nuclear and other radioactive materials.

Prior to this, he served in several leadership roles in EM. Huizenga was instrumental in establishing complex-wide waste management and nuclear materials disposition strategies that were used to accelerate closure of the Rocky Flats Plant and the removal of special nuclear materials from Hanford and other sites. He also worked closely with the Carlsbad Site Office to open the Waste Isolation Pilot Plant, the world’s first deep geologic repository.

Huizenga is known and respected for being a consensus builder and team player both within the U.S government and in the international community. He served four years as the U.S. Senior Technical Advisor on the International Atomic Energy Agency (IAEA) Radioactive Waste Advisory Committee, and most recently was president of the IAEA Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management.
