WASHINGTON — A Canadian company's successful effort to get the United
States to relax a nuclear proliferation law is starting to bear fruit as
the Energy Department prepares to sell it 34 pounds of weapons-grade
uranium. The highly enriched uranium would be used by MDS Nordion of Ottawa to
manufacture radioactive isotopes for use in X-ray machines and other
medical equipment. The Nuclear Regulatory Commission is reviewing an application from the
Energy Department for a license to export the uranium. Most of the medical equipment would be shipped back to the United
States, which does not have a company that manufactures the crucial
diagnostic and therapeutic medical isotopes. Nonproliferation activists, led by University of Texas assistant
professor Alan Kuperman, charge that the sale of highly enriched uranium
to Nordion represents a "giant step back" in national security. Because of the ease with which it can be used to make an atomic bomb,
highly enriched uranium is considered by some proliferation and terrorism
experts as the most dangerous material in the world. Unlike plutonium, the other fissionable substance used in nuclear
weapons, highly enriched uranium can be easily handled, is hard to detect
and can be made into a Hiroshima-type bomb with power tools available in
any hardware store, experts say. "I personally think HEU represents our greatest vulnerability to
nuclear terrorism," Kuperman said of highly enriched uranium. "Only with
HEU can you make a gun-type nuclear weapon, and that is something that is
within the capabilities of terrorist groups." A gun-type weapon, such as the bomb the United States detonated over
Hiroshima, Japan, in World War II, creates an explosion by shooting one
piece of highly enriched uranium into another. Kuperman and other activists see the relaxed U.S. sales policy as
undermining the country's longstanding practice of prodding other nations
to stop using highly enriched uranium. Had Congress not loosened the export controls last year, the pending
sale to Nordion would not have been possible, Kuperman wrote in the
current issue of the Bulletin of the Atomic Scientists. The export control changes were tucked into the 1,754-page energy bill
signed in August by President Bush. The action followed a two-year Nordion-financed lobbying effort in
which its American lobbyists donated thousands of dollars to the campaigns
of key members of Congress, Kuperman says. "It is a cautionary tale of how a single foreign company can weaken
U.S. national security through misleading scare tactics and cold cash," he
wrote. New export rules Kuperman charged in an interview that Nordion got American radiologists
to support its lobbying effort by fooling them into thinking the country's
supply of radioisotopes for diagnostic and therapeutic use would be
threatened without the change. Nordion is the world's largest producer of radioactive medical isotopes
created from a material called molybdenum-99. To make it, manufacturers
bombard uranium-235 with neutrons, transforming a small part of it into
molybdenum-99. In reactors operated for this purpose by Nordion and three large
isotope manufacturers in Europe, both the target metal and the source of
the neutrons that bombard it are highly enriched uranium, in which the
concentration of the uranium-235 isotope has been increased to 90 percent
or more. However, a technology developed at the Energy Department's Argonne
National Laboratory near Chicago makes it possible to make the isotopes
from low enriched uranium, which contains only about 20 percent
uranium-235 and cannot be used to make a bomb. The previous controls, spelled out in a law that Kuperman drafted in
1992 when he worked as an aide to then-Rep. Charles Schumer, D-N.Y.,
require foreign companies that receive highly enriched uranium from the
United States to agree to modify their reactors to use low enriched
uranium. Kuperman said that the new law is "riddled" with loopholes. The new export requirement applies to highly enriched uranium users in
five countries: Canada, Belgium, Germany, the Netherlands and France. It
continues to require isotope manufacturers to work toward converting to
low enriched uranium, but gives them additional time. It also would waive
the requirement if conversion would increase the cost of medical isotopes
in the United States by 10 percent or more. For several years, Nordion qualified for U.S. exports by making the
required commitment to modify its reactors to use low enriched uranium.
But it abandoned the commitment three years ago, Kuperman says. A Nordion spokeswoman did not respond to a request for comment for this
article. Henry Royal, a professor of radiology at Washington University in St.
Louis and past president of the Society of Nuclear Medicine, said that
"when it comes to keeping HEU out of the hands of terrorists, we have much
bigger problems that we should concentrate on." "The last time I checked, Nordion was not a terrorist organization,"
said Royal, who is a consultant to the United Nations Scientific Committee
on the Effects of Atomic Radiation. Credible Kuperman? Kuperman's prominent role in opposing the export of highly enriched
uranium for making medical isotopes has made him a target of
criticism. "He produces a lot of bad information, and I don't trust him," said
Edward McGaffigan, who was appointed to the Nuclear Regulatory Commission
by President Clinton. McGaffigan said the previous controls were so "god-awfully drafted"
that they were all but impossible to enforce. The new law was supported by all members of the NRC and will make it
easier to enforce export controls, McGaffigan said. Royal said Kuperman was "ignoring some basic laws of physics" in his
criticism of the export law changes. Using low enriched uranium to produce medical isotopes would be less
efficient and more expensive because it contains less of the needed U-235,
he said. Others, including an expert on uranium at Argonne, defended Kuperman as
an accurate, if sometimes intemperate, analyst of proliferation
issues. Kuperman, 42, joined the staff of the nonproliferation advocacy group,
Nuclear Control Institute, in 1987 after graduating from Harvard
College. As for the article in the Bulletin of the Atomic Scientists, "I know
that it was thoroughly vetted before they published it," said Paul
Leventhal, fouder of the group. Armand Travelli, who until his retirement in 2004 headed the low
enriched uranium technology program at Argonne, said he had not read
Kuperman's article. "But in general, I have thought the things he
published in the past have been carefully researched," he said, adding,
"He's not very diplomatic, sometimes." After working for the Nuclear Control Institute for two years, Kuperman
went to work for Schumer and earned a master's degree from Johns Hopkins
University School of Advanced International Relations in Washington. He
later received a doctorate in international relations from the
Massachusetts Institute of Technology. He became an assistant professor at UT's LBJ School of Public Affairs
last year. |
