Indian tribes have voiced their tribal issues in the United States‘ nuclear effort since its
inception, with the siting of what would become Los Alamos National Laboratory adjacent to the
San Ildefonso Pueblo Reservation and the Hanford plutonium production works along waterways

Yucca Mountain, Nevada along with other activities conducted on the Nevada National Security
Site (NNSS) (formerly the Nevada Test Site), increased the need for the United States

EPRI has discovered several aspects of the U.S Department of Energy (DOE) proposed design and operation of the Yucca Mountain repository that—if implemented as described in the license application (LA)—could result in unnecessary occupational health and safety risk to workers involved with repository-related activities. This report identifies key DOE conservatisms and focuses on the occupational risk consequences of the DOE's approach to the repository design, performance assessment, and operation.

The key challenge of this National Academy of Public Administration project is captured in the subtitle of this report, Balancing Risks, Costs, and Benefits Fairly Across Generations.

This report highlights the findings and conclusions of the Blue Ribbon Commission on America’s Nuclear Future (BRC) and presents recommendations for consideration by the Administration and Congress, as well as interested state, tribal and local governments, other stakeholders, and the public.
