Andrew Marchese

Mr. Marchese has 48 years’ experience working on reactor and non-reactor nuclear facilities, including his service at DOE, NRC, former AEC, and nuclear safety consulting across the DOE complex and commercial nuclear sites. Mr. Marchese served at the NRC for 15 years from 1975 to 1990 where he was involved in a wide range of reactor safety programs, mainly dealing with advanced reactor safety, severe accidents, and application of risk assessment and cost-benefit techniques to the regulation of older nuclear power plants.

      From 1990 to 1998, Mr. Marchese was a senior nuclear safety manager (SES) at DOE Headquarters where he advised the Secretary of Energy on the safety and risk assessment status of over 50 high hazard nuclear, chemical, and waste storage facilities, including serving as a key member in developing nuclear safety policies, orders, standards and guides.

      As a senior nuclear safety consultant for the past 15 years, Mr. Marchese performs nuclear safety hazard and accident analyses, and safety basis development for private firms and government contractors involved in nuclear facility development and operations. This includes hands-on experience in developing SARs, DSAs, SADs, USQs, and EISs for nuclear, chemical, waste storage, and accelerator facilities. Mr. Marchese has provided nuclear safety consulting at over a dozen nuclear facility sites across the DOE complex, including implementation of DOE-STD-3009 and 10 CFR 830. In addition, having been intimately involved in the development NRC’s severe accident program since the mid-70’s, Mr. Marchese has provided support to NRC’s development of Environmental Impact Statements (EISs) for proposed advanced LWRs in the treatment of accidents beyond the design basis and in writing appropriate sections of EISs on “Postulated Accidents” and “Severe Accident Mitigation Design Alternatives (SAMDAs).” In addition, Mr. Marchese has analysis, design and test experience on liquid-metal cooled reactors and components that dates back to the mid-60’s, including publications in ASME and AIChE Journals.

      Mr. Marchese holds an M.S. Degree in Aeronautical Engineering from M.I.T. and a B.S. Degree in Aerospace Engineering from Pennsylvania State University.

Sustainable Results

iconMr. Marchese has over 40 years of nuclear safety experience. During his 15 year tenure at the U.S. Nuclear Regulatory Commission (NRC), he was responsible for revising general design criteria and establishing appropriate system safety classifications and quality levels for advanced reactor structures, systems, and components. He represented NRC on several ANS Standards Committees, which were responsible for developing advanced reactor general design criteria and establishing guidelines to determine appropriate safety classifications and quality levels for systems important to safety. He played a leading role on: 1) “severe accident” safety analysis work for the proposed Clinch River Breeder Reactor Plant, High-Temperature Gas Cooled Reactors, and Floating Nuclear Plant; and 2) managing NRC’s Unresolved Safety Issue (USI) Program on “Decay Heat Removal Systems.” In addition, he developed regulatory criteria for incorporating a broad range of credible severe accident scenarios into environmental impact statements and risk assessments for commercial NPP facilities, and he pioneered the application of state-of-the-art risk assessment and cost-benefit analysis techniques to the regulation of older nuclear power plants to determine the most effective plant upgrades.

      At the U.S. Department of Energy (DOE), he served as a senior nuclear safety manager in developing national environment, health and safety policies for a broad range of non-reactor nuclear facilities. For example, Mr. Marchese played a lead role in developing DOE Standard, DOE-STD-3009-94, “Preparation Guide for Non-reactor Nuclear Facility Safety Analysis Reports,” which provides the bases for performing hazard and accident analyses for all DOE nuclear facilities, including spent fuel facilities, waste management activities and those facilities undergoing decontamination and decommissioning (D&D). He was also the lead technical manager for reviewing safety analysis reports and environmental impact statements, particularly for the proposed New Production Reactor and the Savannah River K-Reactor. Additionally, he lead the DOE corporate performance measures program to assess improving or deteriorat¬ing conditions at over 200 nuclear, chemical, and waste storage facilities nationwide.

      Since 1998, Mr. Marchese has provided nuclear safety consulting services across DOE complex and commercial nuclear sites. For example, he provided safety basis and environmental impact statement development and upgrades for nuclear facilities at Los Alamos National Laboratory, Savannah River Site, Nevada Test Site, Yucca Mountain Project, Idaho National Engineering Laboratory, Brookhaven National Laboratory, Oak Ridge National Laboratory, Rocky Flats Environmental Technology Site, Hanford Site, and the Waste Treatment Plant Project. This work also included supporting DOE’s Office of NEPA Policy and Compliance, where he reviewed and commented on various DOE Environmental Assessments (EAs) and site wide Environmental Impact Statements (EISs), concentrating on those sections dealing with design basis accidents (DBAs) and severe accidents. In addition, Mr. Marchese is supporting the NRC in the development of EISs for two commercial advanced LWRs in the area of evaluation of accidents beyond the design basis and has hands-on experience in running NRC’s WinMACCS code for severe accident analyses and cost-benefit analysis of Severe Accident Mitigation Design Alternatives (SAMDAs).

      Finally, due to his extensive liquid-metals technology experience, Mr. Marchese has developed several: 1) “White Papers” related to the advantages of liquid-metal cooled “Small Modular Reactors (SMRs),” and 2) publications in ASME and AIChE Journals on “Liquid-Metal Cooled Advanced Reactor Cores.”
