Currently, the world enrichment capacity is approximately 56 million SWU/year, with 22.5 million
SWU/year in GDPs and more than 33 million SWU/year in GCEPs. Most capacity is concentrated in
Russia, the United States, France, and the three Urenco countries, with China and Japan rounding out the
bulk of the capacity. The capacity to produce another 34 million SWU/year is under construction or
planned for the near future, almost entirely using gas centrifuge separation. Laser isotope separation may
become the technology of choice for new enrichment plants in the future, but current enrichment plants
will probably continue operating as long as it is economical to do so.
Politicians and diplomats have discussed the idea of limiting the spread of enrichment technology to
current technology holders, designating a fixed group of enrichment “supplier” countries in the same way
that the list of official nuclear weapon states was established as those countries with nuclear weapons at
the first signing of the NPT in 1968.157,158 Plans for small enrichment programs by states such as Iran,
Brazil, Argentina, South Africa, and Australia may be partially based on the desire to be considered
among these “supplier” countries if such a distinction ever becomes official. One possible alternative is
the creation of international fuel centers,159 such as the proposed center at Angarsk in Russia, which
would make enrichment services more widely available and ensure nuclear fuel supplies for member
states.
The demand for new uranium enrichment
capacity is expected to increase
significantly over the next several decades
(Fig. 39). More fuel will be required for
the nuclear reactors being planned and
built, and the current supply of enrichment
services will start to decrease as the older
GDPs are shut down and alternative
sources of fuel, such as through HEU
blend-down, are depleted (the U.S.-
Russian Megatons-to-Megawatts program
is expected to end in 2013160). As demand
starts to exceed supply, the economics for
investing in new enrichment plants will
begin to look more attractive.

The techniques and implementation of safeguards continue to evolve as the IAEA investigates new
measures and incorporates new technologies.162 The IAEA member states have worked to expand the
scope of the agency’s authority by implementing strengthened safeguards and encouraging states to adopt
an Additional Protocol.163 Advanced safeguards technologies such as more effective enrichment monitors,
unattended monitoring, and uranium cylinder tracking can assist in better meeting the HSP goals of
detecting diversion of declared material at declared facilities; additional measures such as ES and widearea
monitoring provide some capability to detect undeclared materials and facilities.164,165,166 The IAEA
has begun implementing an updated model safeguards approach for GCEPs along with advanced
technology—an effort that began with the HSP in the early 1980s and may continue in the future with an
“HSP+” collaboration between operators and technology holders—to continue to efficiently and
effectively apply safeguards as more uranium enrichment facilities come online in more countries.
