The new capabilities being developed through the Nondestructive Evaluation (NDE) Modeling and Simulation Center are expect- ed to reduce the time, cost and complexity of approaches used to develop and demonstrate NDE techniques to meet regulatory...

Concerns about the reliability of ultrasonic in-service inspections conducted at nuclear power plants led the U.S. Nuclear Regulatory Commission (NRC) to draft a proposed qualification document in October 1984. Representatives from industry, the...

The design and fabrication of nuclear pressure vessels and piping components are governed by the rules of Section III of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code. This Code, which aims to to ensure high...

EPRI is investigating improved inspection technologies as part of a multi-faceted effort to enhance the understanding and management of underground piping and tanks at nuclear power plants. An ultrasonic immersion technique tested on an...

Traditional pressure vessel inspections often require taking assets out of service. However, MISTRAS’ Non-Intrusive Inspection (NII) programs provide data as good or better than internal inspections, while assets remain in service. NII is...
