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 Construction Industry Research and Policy Center (CIRPC) at the University of Tennessee was awarded a contract by the Center to Protect Workers’ Rights, under their grant program with the National Institute of Occupational Safety and Health (NIOSH), to analyze injuries of employees of the U. S. Department of Energy (DOE) and their contractors’ working at DOE work sites. The injury data analyzed were injuries recorded in DOE’s Computerized Accident Incident Reporting System (CAIRS).

The Blue Ribbon Commission on America’s Nuclear Future (BRC) asked us to study whether
occupational safety and health conditions in today's U.S. nuclear industry are reasonably safe,
and if those conditions have improved since the Three Mile Island event in 1979. The BRC also
asked us to look to the future, to try to anticipate worker safety and health risks that should be
addressed by the industry, its government regulators and private watchdogs.
Over the eight weeks allotted, we performed a limited review of the literature and spoke with

Background To determine whether current and former construction workers are at
significant risk for occupational illnesses from work at the Department of Energy’s (DOE)
nuclear weapons facilities, screening programs were undertaken at the Hanford Nuclear
Reservation, Oak Ridge Reservation, and the Savannah River Site.

Construction workers were and are considered temporary workers at many construction sites. Since WWII, large numbers of construction workers were employed at US DOE nuclear weapons sites for periods ranging from a few days to over 30 years. These workers performed tasks during new construction and maintenance, repair, renovation, and demolition of existing facilities.
