The OECD-NEA/RILEM workshop on the “Use and Performance of Concrete in Nuclear Power Plant Fuel Cycle Facilities”, conducted based on a proposal of the Committee on the Safety of Nuclear Installations (CSNI) Working Group on Integrity and Ageing of Components and Structures (WGIAGE), was held in Madrid, Spain on 15-16 March 2004, hosted by Instituto de Ciencias de la Construcción, “Eduardo Torroja”, IETcc/CSIC. The workshop was co-organised with the International Untion of Laboratories and Experts in Construction Materials, Systems and Structures (RILEM) to foster co-operation with experts from the non-nuclear field and to make a significant advance in this area. The NEA Radioactive Waste Management Committee was closely associated.
The overall objective of the workshop was to assess the current practices and the state of the art with respect to the use and performance of concrete (over several centuries) utilised for nuclear power plant fuel cycle facilities. Information obtained as a result of this assessment was utilised to identify issues or “gaps” in the present knowledge for the primary purpose of formulating and prioritising research needs on this topic.
