Environment, safety, and health risk assessment program (ESHRAP)

The Idaho National Engineering and Environmental Laboratory is investigating the development of a comprehensive and quantitative risk model framework for environmental management activities at the site. Waste program risks cover all activities up through final disposition, including storage, handling, treatment, transportation, and disposal. Types of risks addressed include environmental cleanup costs (from accidental releases of radionuclides or chemicals), fatalities from radiological or chemical exposures, and fatalities from standard industrial accidents. Risks are estimated for workers, other site personnel, and the public. Unlike environmental impact statements, safety analysis reports, and performance assessment risk evaluations, the risk model framework being investigated is planned to result in best estimates for environment, safety, and health risks. Two basic types of risk estimates are included: risks from environmental management activities, and long-term legacy (no action) risks from wastes/materials. Both types of risks are estimated using the Environment, Safety, and Health Risk Assessment Program (ESHRAP) developed at the INEEL.
