NEA signs new agreement with the US Department of Energy

Luis Echávarri (right) & Dennis Spurgeon during the signing ceremony On 10 April 2006 the US Department of Energy (DOE) and the NEA signed an Arrangement for Co-operation in the Field of Nuclear Data and Computer Programs. Assistant Secretary for Nuclear Energy, Dennis Spurgeon, signed for the DOE and Director-General Luis Echávarri signed on behalf of the NEA.

The arrangement extends the exchange of nuclear data and computer programs pertinent to civilian nuclear science and technology initiated under the Co-operative Arrangement in the Field of Nuclear Data and Computer Programs signed on 16 December 1985. The new arrangement runs for five years, automatically renewable.

New studies mark twenty years since the Chernobyl accident

The NEA marked twenty years since the Chernobyl accident with two new publications. Stakeholders and Radiological Protection: Lessons from Chernobyl Twenty Years After demonstrates the importance of local involvement in addressing the needs of affected populations to reduce their radiation dose. International Nuclear Law in the Post-Chernobyl Period, jointly published with the International Atomic Energy Agency (IAEA), is a compendium of articles on international nuclear law initiatives since Chernobyl.

Nuclear safety

The first meeting of PRISME joint project participants was held on 3-4 April 2006 in Cadarache, France. The PRISME project will consist of a series of six fire and smoke propagation tests in a dedicated facility at the French Institut de radioprotection et de sûreté nucléaire (IRSN) centre at Cadarache. The facility, which is representative of a series of rooms in a nuclear power plant, will be used to investigate the heat and smoke propagation, the effect of network ventilation and the resulting thermal stresses to sensitive safety equipment, under various configurations. It is also planned to use data from the project to study multi-room fires and for validating fire computer codes. More information is available at

The first meeting of the new stress corrosion cracking and cable ageing (SCAP) programme will be held on 9 June 2006. This programme, a Japanese initiative, will focus on two aspects of ageing management: stress corrosion cracking (SCC) and cable insulation ageing. Its objectives are to: establish a database covering major ageing phenomena for SCC and the degradation of cable insulation; create a knowledgebase of evaluated data; and assess the available data with a view to identifying the basis for best practices which would help regulators and operators to enhance ageing management.

Participants in the Joint Evaluated Fission and Fusion File (JEFF) project will meet on 22-24 May 2006 at NEA headquarters in Paris, France to evaluate the progress of the JEFF, European Fusion File (EFF) and European Activation File (EAF) projects. The current status of ongoing nuclear data benchmarks, processing initiatives and decay data and fission yield libraries will also be discussed. More information is available at

Thermochemical Database (TDB) Project

After two recent plenary meetings of the Thermochemical Database (TDB) Project review teams at the NEA, work is now well advanced on the reviews of thorium (scheduled for peer review in July 2006) and tin (scheduled for peer review in October 2006). The TDB Iron review team will hold its third meeting on 10-12 July 2006 in Paris, France. The TDB Project Management Board, made up of representatives from 17 organisations in 12 member countries will meet on 26-27 October 2006 to examine current progress and future directions of the TDB Project.
