The OECD Nuclear Energy Agency (NEA) organised the Tenth Information Exchange Meeting on Actinide and Fission Product Partitioning and Transmutation (P&T) in Mito, Japan on 6-10 October 2008. The meeting was hosted by the Japan Atomic Energy Agency (JAEA).

Background

Partitioning and transmutation (P&T) is one of the key technologies for reducing the radiotoxicity and volume of radioactive waste produced. Recent developments indicate the need for embedding P&T strategies into advanced fuel cycles considering both waste management and economic issues.

The OECD/NEA has been organising biennial information exchange meetings on actinide and fission product partitioning and transmutation since 1990. The previous meetings were held in Mito (Japan) in 1990, at ANL (USA) in 1992, in Cadarache (France) in 1994, in Mito (Japan) in 1996, in Mol (Belgium) in 1998, in Madrid (Spain) in 2000, in Jeju (Korea) in 2002, in Las Vegas (USA) in 2004 and in Nîmes (France) in 2006.

Scope

The meeting covered scientific, as well as strategic/policy developments in the field of P&T, such as:

Progress reports from countries and international organisations are presented every two meetings. Between these meetings, a specific subject is discussed. This year, a special session on fuel cycle strategies and transition scenarios was organised on the first day to discuss the different approaches and the tools, technology development, and R&D needed to support the transition from the current thermal to future fast reactors.

Programme

The meeting consisted of a special session on fuel cycle strategies and transition scenarios studies on the first day, followed by technical sessions covering all important scientific and technical aspects of P&T-related activities.

Technical visits

Technical tours of the following JAEA facilities were organised on the morning of 10 October.

O-arai site JOYO tour

The experimental fast reactor JOYO is the first sodium-cooled fast reactor in Japan and attained initial criticality as a breeder core on 24 April 1977. The tour consisted of a visit to the control room and other rooms in the containment vessel. More information is available at: www.jaea.go.jp/04/o-arai/joyo/indexes.htm.

Tokai site J-PARC tour

The J-PARC is one of the biggest experimental facilities for not only neutron science, but also high energy physics, basic science and nuclear transmutation. The construction was started in 2002 and various test operations are now under way. Because of the scheduled proton-beam tests, access to the radiation restriction area is prohibited. The tour consisted of a visit to the central control room and observation of other buildings from the bus. More information is available at: http://j-parc.jp/index-e.html.
