This threatening new period has restoked concerns
about nuclear terrorism and brought fresh scrutiny to
security of U.S. nuclear facilities, particularly
nuclear power plants. It also has renewed debate about
the use of highly enriched uranium - or other
materials of bomb-making potential - as fuel in
nuclear research reactors. The fear, of course, is
that the fissile material could be stolen and
ultimately converted into some type of
first-generation atomic weapon by terrorists. The
International Atomic Energy Agency, a conservative
organization with an almost impossible oversight
mission, last week acknowledged the risks of nuclear
terrorism and pushed for upgrades in safety and
security of nuclear facilities and nuclear materials.
