IAEA NUCLEAR ENERGY SERIES PUBLICATIONS
STRUCTURE OF THE IAEA NUCLEAR ENERGY SERIES
Under the terms of Articles III.A and VIII.C of its Statute, the IAEA is
authorized to foster the exchange of scientific and technical information on the
peaceful uses of atomic energy. The publications in the IAEA Nuclear Energy
Series provide information in the areas of nuclear power, nuclear fuel cycle,
radioactive waste management and decommissioning, and on general issues
that are relevant to all of the above mentioned areas. The structure of the
IAEA Nuclear Energy Series comprises three levels: 1 — Basic Principles and
Objectives; 2 — Guides; and 3 — Technical Reports.
The Nuclear Energy Basic Principles publication describes the rationale
and vision for the peaceful uses of nuclear energy.
Nuclear Energy Series Objectives publications explain the expectations
to be met in various areas at different stages of implementation.
Nuclear Energy Series Guides provide high level guidance on how to
achieve the objectives related to the various topics and areas involving the
peaceful uses of nuclear energy.
Nuclear Energy Series Technical Reports provide additional, more
detailed, information on activities related to the various areas dealt with in the
IAEA Nuclear Energy Series.
The IAEA Nuclear Energy Series publications are coded as follows:
NG — general; NP — nuclear power; NF — nuclear fuel; NW — radioactive
waste management and decommissioning. In addition, the publications are
available in English on the IAEA’s Internet site:
http://www.iaea.org/Publications/index.html
For further information, please contact the IAEA at PO Box 100, Vienna
International Centre, 1400 Vienna, Austria.
All users of the IAEA Nuclear Energy Series publications are invited to
inform the IAEA of experience in their use for the purpose of ensuring that
they continue to meet user needs. Information may be provided via the IAEA
Internet site, by post, at the address given above, or by email to

The Agency’s Statute was approved on 23 October 1956 by the Conference on the Statute of the IAEA held at
United Nations Headquarters, New York; it entered into force on 29 July 1957. The Headquarters of the Agency are
situated in Vienna. Its principal objective is “to accelerate and enlarge the contribution of atomic energy to peace,
health and prosperity throughout the world’’.

FOREWORD
Following the ‘Atoms for Peace’ initiative in the 1950s, the technical feasibility and economic viability of
nuclear energy were established in the 1960s, and rapid commercial deployment of nuclear energy ensued around
the world. Today, there are 439 reactors worldwide with a total generating capacity of 372 GWe. In the late 1960s
and early 1970s, the nuclear energy growth rate was expected to rise rapidly and the adequacy of uranium resources
became a growing concern. As a result, the development of fast breeder reactors became a priority in France, India,
Japan, the Russian Federation, the United Kingdom and the United States of America, as well as in other countries.
Sustainable development of nuclear energy calls for the development of innovative nuclear energy systems
with highly efficient utilization of fissile and fertile resources. However, today’s commercial thermal reactors
utilize less than 1% of total uranium resources. Hence, developmental efforts in recycling plutonium as well as
minor actinides in current and future innovative nuclear energy systems are under way in several Member States.
Additionally, plutonium recycling in LWRs has been pursued as an interim step toward an ultimate closed fuel cycle
within fast breeder reactors. Furthermore, during the past two decades or so, new R&D programmes have been
launched in several Member States to develop alternate reprocessing techniques and advanced partitioning
processes that might aid in nuclear waste management. Current reprocessing techniques only recover uranium and
plutonium. Advanced processes aim to recover minor actinides and other long lived fission products for the purpose
of transmuting them in reactors.
The IAEA has been closely involved for many years in fostering collaborative R&D efforts and information
exchange among Member States in development of innovative nuclear energy systems, including innovative
nuclear fuel cycles approaches. The purpose of this report is to summarize the current status of minor actinide
containing fuel types under development, fabrication processes for such fuels, pertinent thermal and physical
properties, and irradiation test results. More importantly, these R&D programmes will be put into the context of
appropriate fuel cycle options for actinide recycling and their implications on the future expansion of nuclear
energy.
The contributions of the experts who helped draft and review this report, are greatly appreciated. In particular,
the IAEA expresses its gratitude to M. Mayer (USA) for chairing the review group and for his significant
contribution in the preparation of this report. Thanks are also extended to Y.I. Chang of the Argonne National
Laboratory (USA) for a critical review of the draft and final editing.
The IAEA officer responsible for this publication was H.P. Nawada of the Division of Nuclear Fuel Cycle and
Waste Technology.
