IAEA 8th IEM on P&T, Las Vegas, Nevada, 9-11 November 2004 2
IAEA Activities
• Implemented in collaboration by IAEA’s Nuclear Power Technology Development and Nuclear Fuel Cycle and Materials Sections
• Framework given by the Technical Working Groups on Fast Reactors (TWG-FR) and on Nuclear Fuel Cycle Options (TWG-NFCO)
IAEA 8th IEM on P&T, Las Vegas, Nevada, 9-11 November 2004 3
Technical Working Group on Fast Reactors (TWG-FR)
• TWG-FR working tool toPromote exchange of information on
national and multi-national fast reactor and hybrid systems (e.g., ADS) programs
Stimulate and facilitate collaborative research and development (CRPs)
Coordinate activities with other Agency projects (e.g., in Safety), and international organizations (EC and NEA)
IAEA 8th IEM on P&T, Las Vegas, Nevada, 9-11 November 2004 4
Membership of the TWG-FR
Belarus, Brazil, China, France, Germany, India, Italy, Japan, Kazakhstan, Republic of Korea, Russia, Switzerland, United Kingdom, and United States of America, as well as the EU (EC), and OECD/NEA
Observers: Sweden, Turkey

States, and the EC (JRC)Comparative assessment of the transient behaviour
of advanced transmutation systemsBoth critical and sub-critical systems to be
consideredcritical liquid metal, and gas cooled fast reactorheavy liquid metal, and gas cooled ADS critical and sub-critical molten salt reactor fusion-fission hybrid sub-critical reactor
