An End State Methodology for Identifying Technology Needs for Environmental Management, with an Example from the Hanford Site Tanks

by National Research Council

A major issue in the cleanup of this country's nuclear weapons complex is how to dispose of the radioactive waste resulting primarily from the chemical processing operations for the recovery of plutonium and other defense strategic nuclear materials. The wastes are stored in hundreds of large underground tanks at four U.S. Department of Energy (DOE) sites throughout the United States. The tanks contain hundreds of thousands of cubic meters of radioactive and hazardous waste. Most of it is high-level waste (HLW), some of it is transuranic (TRU) or low- level waste (LLW), and essentially all containing significant amounts of chemicals deemed hazardous. Of the 278 tanks involved, about 70 are known or assumed to have leaked some of their contents to the environment. The remediation of the tanks and their contents requires the development of new technologies to enable cleanup and minimize costs while meeting various health, safety, and environmental objectives. While DOE has a process based on stakeholder participation for screening and formulating technology needs, it lacks transparency (in terms of being apparent to all concerned decision makers and other interested parties) and a systematic basis (in terms of identifying end states for the contaminants and developing pathways to these states from the present conditions). An End State Methodology for Identifying Technology Needs for Environmental Management, with an Example from the Hanford Site Tanks describes an approach for identifying technology development needs that is both systematic and transparent to enhance the cleanup and remediation of the tank contents and their sites. The authoring committee believes that the recommended end state based approach can be applied to DOE waste management in general, not just to waste in tanks. The approach is illustrated through an example based on the tanks at the DOE Hanford Site in southeastern Washington state, the location of some 60 percent by volume of the tank waste residues.

About the author

The National Research Council (NRC) functions under the auspices of the National Academy of Sciences (NAS), the National Academy of Engineering (NAE), and the Institute of Medicine (IOM). The NAS, NAE, IOM, and NRC are part of a private, nonprofit institution that provides science, technology and health policy advice under a congressional charter signed by President Abraham Lincoln that was originally granted to the NAS in 1863. Under this charter, the NRC was established in 1916, the NAE in 1964, and the IOM in 1970. The four organizations are collectively referred to as the National Academies.

The mission of the NRC is to improve government decision making and public policy, increase public education and understanding, and promote the acquisition and dissemination of knowledge in matters involving science, engineering, technology, and health. The institution takes this charge seriously and works to inform policies and actions that have the power to improve the lives of people in the U.S. and around the world.

The NRC is committed to providing elected leaders, policy makers, and the public with expert advice based on sound scientific evidence. The NRC does not receive direct federal appropriations for its work. Individual projects are funded by federal agencies, foundations, other governmental and private sources, and the institution’s endowment. The work is made possible by 6,000 of the world’s top scientists, engineers, and other professionals who volunteer their time without compensation to serve on committees and participate in activities. The NRC is administered jointly by the NAS, NAE, and the IOM through the NRC Governing Board.

The core services involve collecting, analyzing, and sharing information and knowledge. The independence of the institution, combined with its unique ability to convene experts, allows it to be responsive to a host of requests.

The portfolio of activities includes:

* Consensus Studies: These comprehensive reports focus on major policy issues and provide recommendations for solving complex problems.
* Expert Meetings and Workshops: By convening symposia, workshops, meetings, and roundtables, the NRC connects professionals as well as the interested public and stimulates dialogue on diverse matters.
* Program and Research Management: At the request of state and federal agencies, the NRC manages and evaluates research programs, conducts program assessments, and reviews proposals.
* Fellowships: The NRC administers several postdoctoral fellowship programs.

Free Scientific Information: Publishing more than 200 reports and related publications each year, the institution is one of the largest providers of free scientific and technical information in the world. Most of it is now on the Web at www.nap.edu.
