TH27  Concrete Degradation Part I: Perspectives on Alkali-Silica Reaction Effects on the Structural Capacity of Nuclear Concrete Structures

In this session, speakers will describe the current research on the effects of alkali-silica reaction (ASR) degradation on the structural capacity of nuclear concrete structures. The speakers will present research to date on ASR effects on structural capacity being conducted at the National Institute of Standards and Technology, the Observatoire de la Durabilité des Ouvrages en Béton Armé concrete degradation research being conducted by the Institut de Radioprotection et de Sûreté Nucléaire in France, ASR research sponsored by the U.S. Department of Energy/Electric Power Research Institute, new innovative research to formulate and validate a stochastic framework for the prediction of concrete aging and deterioration at Northwestern University, and results of the Organisation for Economic Co-operation and Development/Nuclear Energy Agency/Committee on the Safety of Nuclear Installations benchmark tests on ASR concrete presented by the Canadian Nuclear Safety Commission.
