Environmental Assessment and Engineering Group


The Environmental Assessment and Engineering (EA&E) technical group is a team of scientists, engineers, and project managers located within the Energy and Environmental Directorate of Pacific Northwest National Laboratory (PNNL). With diverse skills and expertise, the EA&E Group builds on its collective capabilities to provide comprehensive solutions addressing some of our nation's most complex challenges in energy systems siting and licensing; environmental characterization, monitoring, and remediation; and national security measures.

    A suite addition brings a new flavor of nuclear research capabilities to PNNL's Radiochemical Processing Laboratory.

  • PNNL Staff Are Among the 'Titans of Nuclear'

    PNNL Staff Are Among the 'Titans of Nuclear'

    International podcast aims to educate the tech-savvy on nuclear energy by interviewing experts on topics including reactors, regulation, rare earth elements, and risk analysis. Among the Titans of Nuclear interviewees are PNNL’s Steve Unwin, Tara O’Neil, Brady Hanson, Ron Omberg, and Chad Painter.

  • Next-Gen Radiation Portal Monitoring

    Next-Gen Radiation Portal Monitoring

    Rick Cameron and team are designing, engineering, and testing next-generation interdiction systems at locations throughout the U.S. for national security purposes. The team checks the accuracy and durability of recently fielded equipment, including remote and automated systems and fixed and mobile installations, and analyzes the integrity of current monitoring systems.

  • EA&E Nuclear Materials Projects

    EA&E Nuclear Materials Projects

    EA&E staff are addressing a broad set of environmental, and regulatory, and border-security projects involving the storage, detection, and safe disposition of our nation’s nuclear materials. From siting small nuclear reactors to detecting illicit materials at the U.S. borders, from responding to emergencies to safe disposition and storage of spent nuclear materials, EA&E staff are solving problems and leading our nation into a safer, cleaner future.

  • Mart Leads Team Creating DOE Standard for EM

    Mart Leads Team Creating DOE Standard for EM

    Eva Mart led a PNNL project team in developing a new DOE Standard, Emergency Management Program Administration: Criteria Review and Approach Document for Risk-Informed and Performance-Based Assessments. The goals are to create an enhanced process for consistently assessing emergency management (EM) programs across the DOE complex and to implement a risk-informed, performance-based oversight tool for DOE EM programs.

  • Surrogate Waste Tests at Field Lysimeter Test Facility

    Surrogate Waste Tests at Field Lysimeter Test Facility

    A project to assess the integrity of low-activity waste (LAW) waste forms will use the Hanford Site Field Lysimeter Test Facility. The study will produce surrogate waste forms and monitor their wastewater streams for evidence of degradation. The study aims to improve stakeholder confidence in the safe disposal of LAW.
