environmental management
Environmental Management

The DOE Office of Environmental Management (EM) was created in 1989 to

Address the environmental legacy from over 50 years of nuclear weapons research, production, and testing - some of the most technically challenging and complex work of any environmental program in the world

environmental legacy nuclear weapons production
Environmental Legacy: Nuclear Weapons Production

SOURCE:

Accumulation from 50 years of nuclear weapons production by the U.S. Department of Energy (DOE) and its predecessors

doe environmental legacy1
DOE Environmental Legacy

DOE Problem Wastes - Examples

- 403,000 cubic meters of high level waste (HLW)

- 250,000 cubic meters of solid transuranic wastes (TRU)

- 4.4 million cubic meters of low level waste (LLW)

  • Non-radioactive hazardous wastes and mixed wastes
  • 5,000 – 7000 contaminated facilities

DOE Environmental Legacy

DOE Environmental Problems

  • 5,700+ individual plumes contaminating soil and groundwater
  • 7.8 Km2 plume at SRS
  • 18.1 Km2 plume of CCl4 at Hanford
  • 710,000 m3 of soil at NTS

the legacy continues
The Legacy Continues
  • More contamination and waste will be identified as characterization continues
  • Decontamination wastes???
  • Secondary waste streams from clean-up operations
  • Long-term stewardship of sites where residual contamination remains
why do we need basic research for the cleanup
Why Do We Need Basic Research for the Cleanup?
  • We have never done this before
  • To provide a technical basis for making decisions
  • To provide new approaches to cut costs, or sometimes just to provide approaches
  • To resolve technical problems as the cleanup progresses

galvin commission 1995
Galvin Commission, 1995

“There is a particular need for long term, basic research in disciplines related to environmental cleanup … Adopting a science-based approach that includes supporting development of technologies and expertise … could lead to both reduced cleanup costs and smaller environmental impacts at existing sites and to the development of a scientific foundation for advances in environmental technologies.”

From the 1995 Galvin Commission Report On the Department of Energy Laboratories

R&D for solutions to DOE’s long-term environmental cleanup challenges

The Environmental Management Science Program (EMSP) is developing the scientific basis for risk-based decision making and “breakthrough” approaches to cleaning up the nuclear weapons complex.

Bioremediation Research (NABIR) provides the understanding of how microbes that naturally exist in soils can stabilize metals and radionuclides. Studies span the range of microbial genetics of all the way to field studies at actual contaminated sites.

The Environmental Molecular Sciences Laboratory (EMSL) is serving environmental users from around the world by providing the leading edge of computational and experimental capabilities for understanding processes at the molecular level.

The Savannah River Ecology Laboratory (SREL)is studying the ecological impacts of remediation activities in real time at the Savannah River Site while providing hands-on educational programs at the Site.

Environmental Remediation Sciences: FY03 Budget (thousands of $)

NABIR $24,720

EMSP $29,900

EMSL $38,000 (operations)

SREL $ 6,800

Misc. $10,100

Total $109,500

Minus ~12M for unfunded Congressional earmarks in FY03!

Largest program of its kind anywhere!

strategic planning for environmental remediation sciences
Strategic Planning for Environmental Remediation Sciences

NRC Recommendation:

“…that DOE develop a strategic vision for its Environmental Quality (EQ) R&D portfolio. This vision should provide the framework for developing the science and technology necessary to address EQ problems that extend beyond the present emphasis of short-term “compliance” and should incorporate the principal of continual improvement.”

A Strategic Vision for DOE Environmental Quality R&D(National Academy Press, 2001)

strategic planning
Strategic Planning
  • 2 Strategic Planning workshops (July and September, 2002)
    • Involved scientists from all relevant disciplines, other DOE offices, other agencies
    • Used NRC Reports on EM Science needs as a basis
  • Formation of BERAC Subcommittee
    • 1st meeting in April 2003
    • Reviewed Strategic Plan Draft
  • Draft II is on its way!

Environmental Remediation Sciences: Mission

Enable scientific advances that help solve currently intractable environmental problems or otherwise provide break-through opportunities for DOE environmental missions, while also contributing to the general advance of the scientific fields involved.

environmental remediation sciences goals
Environmental Remediation Sciences: Goals
  • Provide science to inform decisions about environmental remediation and stewardship
  • Advance scientific foundations that enable innovative remediation technologies and methodologies
  • Synthesize and integrate across disciplines to foster new scientific approaches that match the complexity of the problems
ersd characteristics
ERSD Characteristics

      • Where science can have the greatest impact
  • Highly interdisciplinary – integrates results from biology, geology, chemistry, ecology, etc.
  • Committed to developing and supporting a suite of field research sites
  • Develop a “toolbox” of characterization and monitoring tools.

programmatic challenges
Programmatic Challenges
  • Integrating the science across the division programs
  • Fostering interdisciplinary research teams
  • Nurturing truly innovative ideas
  • Getting our science used
getting our science used
Getting our science used
  • Work directly with cleanup staff at sites to identify and collaborate on the field research sites.
  • Work on specific site problems
  • Sponsor frequent technical exchange workshops with sites
  • Develop a strategy to “advertise” our successes.
opportunities
Opportunities
  • to “revolutionize” environmental studies—bringing much-needed rigor and the new tools of genomics, nanoscience, and computing to bear.
  • to have far-reaching impacts on the way environmental issues are approached.
  • to apply to a broader set of problems (e.g. water quality, future energy options, waste minimization, mining and industrial wastes)
