Area of Science:

  • Environmental Science
  • Nuclear Engineering
  • Radiation Detection

Background:

  • Hanford site requires comprehensive characterization for environmental restoration.
  • Decontamination and decommissioning (D&D) activities necessitate accurate contamination data.
  • Regulatory requirements for site release demand thorough assessment of residual radioactivity.

Purpose of the Study:

  • To present the Advanced Characterization System (ACS) for radiological surveys.
  • To detail the application of ACS in characterizing large structures and land areas at Hanford.
  • To demonstrate the utility of ACS for operational and release decisions.

Main Methods:

  • Utilizes a staged system of commercial radiation detection equipment.
  • Employs gamma-ray imaging, in situ gamma spectrometry, and large-area survey meters.

  • Integrates data logging for comprehensive contamination mapping.

    • Main Results:

    • ACS effectively locates and identifies contamination in structures, systems, and land.
    • Generates high-quality data for informed D&D, disposal, and release decisions.
    • Enables safe characterization of in-place systems without containment breaches.

    Conclusions:

    • The ACS provides a robust solution for radiological characterization at complex industrial sites.
    • The system facilitates efficient and safe decision-making for environmental restoration projects.
    • ACS supports the ultimate goal of site cleanup and release for beneficial reuse.
