Estimation of the state of the metal of pipelines of nuclear power plants after 100,000 hours of operation
1998
We analyze the results of an examination of the metal of pipelines of nuclear and thermal power plants performed within the framework of complex programs aimed at the prolongation of the service life of pipelines. We suggest an approach to the estimation of the state of the metal of pipelines and equipment of nuclear power plants after 100,000 h of operation. This approach gives reliable data on the mechanical properties and characteristics of fracture toughness of the metal and enables one not to cut out samples of the metal from pipelines.
