Biography

Prior waste generation activities dating back to the 1940's nuclear weapons mission paired with the impact of contaminants in the environment have resulted in the necessary ability to make critical cleanup decisions. Pacific Northwest National Laboratory develops and delivers science-based and risk-informed solutions to make water, soil, and air cleaner. Our goal is to enable cleanup for complex challenges in waste processing and environmental remediation and stewardship with a depth of expertise and objectivity that promotes public confidence in the country's ability to manage the nuclear legacy and achieve environmental protection.

To achieve this, we are integrating our fundamental science-based understanding with applied research to deliver systems-based solutions. Our approaches enable predictive understanding of system performance for managing and monitoring residual DOE tank waste, waste processing, immobilization and disposal, environmental remediation, restoration, and stewardship (see interactive web feature). Equally important, we facilitate interactions with stakeholders, regulators, and the public by providing scientific and technical understanding necessary to provide solutions and inform the risks, liabilities, and economics of complex cleanup challenges as the nation strives to achieve environmental protection.

The Environmental Health and Remediation focus areas include: Chemical and Nuclear Processing, Subsurface Science and Engineering, Energy-Water Nexus, Radiation Measurements and Irradiation, Climate Change Modeling and Decision Science, Landscape Scale Management and Resilient Coastal Systems.

    Rising Stars of Robotics

    Some of the brightest young minds in robotics are coming to PNNL—and they're going to build highly advanced robotics systems designed for extremely contaminated areas that pose a high risk of exposure to human workers. Under the new program, Carnegie Mellon University will send graduate students for two-year internships under the guidance of national lab staff.

  • Bench-scale testing of the vapor monitoring and detection system included controlled releases of both smoke and chemicals of interest into a small area outside a PNNL lab.

    True Detection

    PNNL is helping to assess vapor monitoring and detection equipment as part of DOE efforts to further improve worker safety at the Hanford Site tank farms.

    New Insights from Old Glass

    How might old—really old—glass immobilize radioactive waste at the Hanford Site in southeastern Washington state? Researchers are seeking answers from walls containing ancient glass in Europe. These walls, known as hillforts, are defense structures that date as far back as the Bronze Age.
