REPAIR MATERIALS AND TECHNIQUES FOR CONCRETE STRUCTURES IN NUCLEAR-POWER-PLANTS

The paper summaries portions of work of the Structural Aging Program, sponsored by the Nuclear Regulatory Commission (NRC). The paper addres ses the assessment and repair of concrete structures in nuclear power plants. It presents the results of a survey of the the nuclear power p lants in the United States to identify susceptible concrete components , rates of occurrence of deterioration, and to determine the durabilit y of repairs. The paper describes deterioration mechanisms and discuss es their effect. Repair techniques are described. Evaluation technique s and nondestructive test techniques are also discussed.
