Ensuring property is safe for release

The Oak Ridge Institute for Science and Education (ORISE) performs independent environmental assessments and verification to determine the effectiveness of radiological cleanup at decontamination and decommissioning (D&D) projects across the United States. Since 1980, ORISE has performed independent verification at more than 500 sites in 42 states and the District of Columbia. 

ORISE serves as the key independent verification contractor for U.S. Department of Energy (DOE) cleanup projects and the only verification contractor for the U.S. Nuclear Regulatory Commission (NRC). In this role, ORISE assures that soil, water and structures are within established state and federal release criteria for public use. 

Independent evaluation is crucial to providing an unbiased analysis of the D&D process and outcome. ORISE examines final site conditions and final status survey procedures, thus verifying that the remediation meets the release criteria. 

During site verification, a team of qualified radiological experts follows systematic procedures to collect environmental samples using specialized equipment, including radiation detectors and monitors, spectrometers and Global Positioning Systems. Environmental samples are then thoroughly analyzed at the Radiological and Environmental Analytical Laboratory.

The benefits of ORISE independent verification include:

  • Provides assurance that the site was remediated to the risk-based release criteria
  • Enhances credibility to the public and builds stakeholder trust in environmental cleanup
  • Provides DOE and regulatory agencies with independent, technical advice and consultation
  • Helps prevent an improper release of property that is not in regulatory compliance
