Draft Environmental Impact Statement for the Disposal of Greater-Than-Class C Low-Level Radioactive Waste and GTCC-Like Waste
WASHINGTON � The Department of Energy
(DOE) has issued a Draft
Environmental Impact Statement for the Disposal of
Greater-Than-Class C (GTCC) Low-Level Radioactive Waste
(LLRW) and GTCC-Like Waste (DOE/EIS-0375D, Draft EIS) as
required under the National Environmental Policy Act for
public review and comment.
GTCC LLRW consists of a small volume of low-level
radioactive waste generated throughout the United States as
the result of Nuclear Regulatory Commission (NRC) and
Agreement State licensed activities, including production of
electricity from nuclear power plants; the production and
use of radioisotopes for diagnostics and treatment of cancer
and other illnesses; oil and gas exploration; and other
industrial uses. "GTCC-like" waste consists of DOE owned or
generated LLRW and potential non-defense transuranic waste
which is similar to GTCC LLRW and for which there is
currently no available disposal capability. GTCC LLRW and
GTCC-like waste does not include spent nuclear fuel or
high-level waste.
The total volume of GTCC LLRW and GTCC-like waste
currently in storage is approximately 1,100 cubic meters.
Over the next 60 years, the Draft EIS estimates that on
average, an additional 175 cubic meters will be generated
each year from commercial and DOE, primarily from cleanup
operations. This amounts to a little more than the volume of
an average garage each year.
Although the amount of waste is relatively small, safe
and secure disposal of this material would support important
medical activities and address national security concerns
associated with certain disused sealed sources.
Safe and Secure Disposal Will Contribute to National
Security
One type of GTCC-waste, called "sealed sources," includes
small, high-activity radioactive materials encapsulated in
closed metallic containers, which represent about a quarter
of the total volume of GTCC wastes. Today, many disused
sealed sources are stored at hospitals, construction sites,
universities, and other locations awaiting disposal.
Due to their concentrated activity and portability,
radioactive sealed sources could be used in radiological
dispersal devices, like dirty bombs, and pose a national
security risk.
Safe and Secure Disposal Will Support the Future of
Nuclear Medicine
The availability of a GTCC disposal path is important to
the future of nuclear medicine, especially for the planned
domestic production of Molybdenum-99 (Mo-99) which is used
in as many as 50,000 diagnostic medical procedures every day
in the U.S.
Today, the U.S. depends on foreign nuclear reactors to
produce Mo-99, but shortages in recent years have
highlighted the need to produce this material domestically.
Commercial entities in the U.S. are developing the
capability to produce Mo-99, but will require a safe and
secure method to dispose the GTCC waste resulting from the
production of Mo-99.
A Range of Disposal Methods and Locations Are Evaluated
The Draft EIS analyzes potential environmental impacts
from constructing and operating a new facility or facilities
for the disposal of GTCC and GTCC-like wastes, as well as
the impacts of using an existing facility.
Several disposal methods were evaluated, including: deep
geological repository, intermediate depth boreholes,
enhanced near surface trenches, and above grade vaults.
Disposal locations analyzed include the Hanford Site in
Washington; Idaho National Laboratory in Idaho; the Los
Alamos National Laboratory, the Waste Isolation Pilot
Project (WIPP), and the WIPP vicinity in New Mexico; the
Nevada National Security Site (formerly the Nevada Test
Site) in Nevada; and the Savannah River Site in South
Carolina. The Draft EIS also evaluates generic commercial
disposal sites in four regions of the U.S., as well as a no
action alternative.
DOE does not have, and did not identify, a "preferred
alternative" for the disposal of GTCC and GTCC-like waste.
DOE will include a preferred alternative in the Final EIS
based on the analysis in the Draft EIS and public comments
received. The preferred alternative could be a combination
of two or more alternatives, based on the characteristics of
the waste and other key factors. Before DOE makes a final
decision on a disposal method or location, DOE must submit a
report to Congress that includes a description of the
alternatives under consideration and await action by
Congress.
The Draft EIS provides the public and interested
stakeholders with information on options for the disposal of
GTCC and GTCC-like waste. A Federal Register Notice will be
published on February 25, 2011 and will start a 120-day
public comment period, during which DOE will hold meetings
at the DOE sites that are evaluated in the Draft EIS for the
disposal of GTCC and GTCC-like waste.
