Prior to 1992, the Department of Energy relied on underground testing at its Nevada Test Site to
ensure the safety, reliability, and performance of the Nation's nuclear weapons. When the United
States placed a moratorium on underground testing, the Department implemented a sciencebased
Stockpile Stewardship Program, designed to certify that the weapons are safe and, if
needed, will work as intended. This program is a key mission of the Department's National
Nuclear Security Administration (NNSA).ie8yah
As agencies strive to meet the President's goal of significantly increasing electronic government, the potential for disruption or damage to critical systems by malicious users continues to increase. In response to increasing threats to the Government's computer networks and systems, Congress enacted the Government hformation Security Reform Act (GISRA) in October 2000. GISRA focuses on program management, implementation, and evaluation of the security of unclassified and national security information. It requires agencies to conduct annual reviews and evaluations of unclassified and classified computer security programs.
As a result of Cold War weapons production, the Department of Energy accumulated millions
of gallons of high-level waste that now require treatment and final disposal. At the
Department's Savannah River Site, there are approximately 38 million gallons of high-level
waste, including 35 million gallons of salt waste and 3 million gallons of sludge. To treat the
salt waste, the Department originally planned to process the waste through the Savannah River
Site's In-Tank Precipitation Facility so that cesium and other radionuclides could be removed.
However, in February 1998, the Department suspended operation of the In-Tank Precipitation
Facility because it could not be operated safely.aP6A==
The Department of Energy (Department) faces an environmental remediation task of unprecedented scope
and technical complexity. Current estimates are that the clean-up effort will eventually cost more than $230
billion and take decades to complete. At your direction, the Department recently completed a comprehensive
evaluation of its remediation effort with a goal of finding a way to reduce associated costs, as well as the time
needed to complete the task. Given the nature of the work, the effort will likely involve many as yet untested
technologies. In this vein, the Assistant Secretary for Environmental Management has established a priority
to identify breakthrough technologies with the potential to dramatically reduce the Department's remediation
mortgage costs.
