Legacy of Reprocessing in SC
South Carolina has its own tragic environmental
legacy from nuclear reprocessing. In 1999, the Institute
for Environmental Research described the situation at our
Savannah River Site (SRS):
SRS is
“the single greatest environmental risk in the state
of South Carolina.” |
“In South Carolina alone, reprocessing
is responsible for creating the most radioactive waste
in the country – over 30 million gallons of high-level
liquid waste [and] tens of thousands of containers of
solid radioactive waste which is buried just a few miles
from the Savannah River. Already some of that waste has
moved into soils and groundwater at SRS….” MORE
Today, liquid radioactive waste at the Savannah
River Site has increased to nearly 36.5 million gallons.
Of the facility’s 49 tanks, 12 have a history of leaks. MORE
A recent report details even more primitive
disposal methods than leaky tanks, including unlined basins
that were actually designed to release radioactive liquid
into the ground. Given the site’s “high water
table…permeable surface, many wetlands, ponds, swamps,
streams and creeks…and high annual rainfall,” it
is not surprising that “there are already large plumes
of radioactivity moving away from contaminated areas on site.” MORE at 196-98.
Even more disconcerting is the fact that, to
date, no one is sure how to clean it all up. The federal
Department of Energy’s Office of Environmental Management
(“EM”) recently asked the National Academies
to provide advice on its plans to clean up the Savannah River
Site and three similar facilities. In a January 2008 meeting,
Savannah River Site staff told the National Academies:
“Radioactive waste stored in SRS
tanks poses the single greatest environmental risk in
the state of South Carolina.”
In February 2008, the Academy issued an interim
report, saying:
“[E]xisting knowledge and technologies
are inadequate for EM to meet all of its cleanup responsibilities
in a safe, timely, and cost-effective way.” MORE
In particular, the National Academies commented
that a “very expensive and long-term problem for the
EM cleanup program involves retrieval of waste from the tanks
at the Savannah River Site…” The National Academies
also noted that “important groundwater and soil remediation
problems remain unresolved.” MORE
However, the National Academies could not provide
a specific recommendation, because cleanup technology does
not currently exist. Instead, they advised the Department
to pursue:
“additional R&D…to improve
waste retrieval, waste processing, and tank closure [and
s]ustained R&D investments…to develop monitoring
strategies for containment options….. ” MORE
In other words, management of waste at the
Savannah River Site is still in an experimental stage. Progress
is being made on retrieving liquid waste from leaky tanks
and storing it in a safer form. Also, R&D is actively
underway to improve the process. Nonetheless, locating a
new preprocessing complex at the Savannah River Site would
only compound the problems posed by “the single greatest
environmental risk in the state of South Carolina.” |
