IAEA Activities in the Area of Partitioning and Transmutation Alexander Stanculescu Nuclear Energy Department Nuclear Power Technology Development Section
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) 8th IEM on P&T, Las Vegas, Nevada, 9-11 November 2004
Technical Working Group on Fast Reactors (TWG-FR) • TWG-FR working tool to • Promote 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) 8th IEM on P&T, Las Vegas, Nevada, 9-11 November 2004
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 Membership of the TWG-FR 8th IEM on P&T, Las Vegas, Nevada, 9-11 November 2004
TWG-FR Annual Meetings • Last meeting held in Vienna, IAEA Headquarters, 10 – 14 May 2004 • Next meeting will be hosted by Instituto de Pesquisas Energéticas e Nucleares (IPEN), in São Paulo, Brazil,23 – 27 May2004 8th IEM on P&T, Las Vegas, Nevada, 9-11 November 2004
