Area of Science:

  • Environmental Science
  • Nuclear Engineering
  • Radiation Detection

Background:

  • Hanford site requires comprehensive characterization for environmental restoration.
  • Decontamination and decommissioning (D&D) necessitate accurate contamination identification.
  • Existing methods may not fully address complex structures and land areas.

Purpose of the Study:

  • To introduce the Advanced Characterization System (ACS) for efficient contamination assessment.
  • To detail the ACS's application in locating and identifying radioactive contamination.
  • To support operational and release decisions at Environmental Restoration Contractor (ERC) work sites.

Main Methods:

  • Utilizing commercial radiation detection and measurement equipment in a staged system.

  • Employing gamma-ray imaging, in situ gamma spectrometry, and large-area survey meters.
  • Integrating data logging for comprehensive site characterization.

    • Main Results:

    • The ACS effectively locates and identifies contamination in structures, systems, and land.
    • Sufficient quality data is generated for operational and release decisions.
    • Safe characterization of in-place systems without containment breaches is achieved.

    Conclusions:

    • The ACS provides a robust solution for characterizing complex contaminated environments at Hanford.
    • The system facilitates informed D&D, disposal, and site release strategies.
    • ACS enhances safety and efficiency in radiological assessments.
