A closer look at NRC’s proposed rule eliminating ALARA
On July 1, the Nuclear Regulatory Commission proposed removing the “as low as reasonably achievable” (ALARA) principle from its radiation protection regulations and replacing it with a graded approach. The agency also proposed increases to effluent dose limits and adjusting how it handles allowances for exceeding dose limits.
2022 International High-Level Radioactive Waste Management Conference Speaker
Dr. Robert Ledoux currently serves as a Program Director at the Advanced Research Projects Agency—Energy. His areas of interest include the intersection of nuclear physics and non-proliferation, energy production, and transportation. He is the program director of the ARPA-E ONWARDS program, which aims to reduce the disposal impact of advanced reactor waste.
Prior to joining ARPA-E, Dr. Ledoux served as the Founder, President, and CEO of Passport Systems, a technology company in non-intrusive cargo inspection. At Passport Systems Dr. Ledoux co-invented powerful new technologies with the US Department of Homeland Security Domestic Nuclear Detection Office to aid in the non-intrusive inspection of cargo and co-authored over 20 US and international patents. Prior to founding Passport Systems, he served as Vice President of Pyramid Technical Consultants, developing hardware and software for the control of magnetic scanning systems and accelerator control used in semiconductor manufacturing equipment. Previously as an Associate Professor of Physics at the Massachusetts Institute of Technology, he studied high-energy nuclear interactions in search of new phases of hadronic matter.
