The nuclear industry uses nondestructive testing (NDT) techniques to ensure the safety, reliability, and performance of its products and operations. Nuclear NDT is the application of NDT methods and techniques in the nuclear industry, to inspect and evaluate the structural integrity, serviceability, and quality of nuclear components, materials, and systems.

Nuclear NDT plays a critical role in the design, manufacture, maintenance, and repair of nuclear components and systems, including reactors, fuel assemblies, and other systems. Nuclear NDT is used to detect and diagnose defects, flaws, and other imperfections that can affect the safety, performance, and durability of nuclear components and systems.

Nuclear NDT typically involves the use of advanced and specialized NDT methods and techniques, such as radiographic testing, ultrasonic testing, eddy current testing, magnetic particle testing, and liquid penetrant testing. These methods and techniques allow nuclear NDT technicians to inspect and evaluate the internal and external surfaces, structures, and properties of nuclear components and systems, without causing any damage or disruption to their function and operation.

Nuclear NDT is performed by qualified and certified NDT technicians, who have the skills, knowledge, and experience to apply the appropriate NDT methods and techniques, and to interpret and evaluate the results of the NDT inspections. Nuclear NDT technicians typically work in nuclear power plants and research facilities, and are responsible for ensuring the quality, reliability, and safety of nuclear products and systems.

Nuclear NDT is regulated by national and international standards and guidelines, such as the American Society for Nondestructive Testing (ASNT) and the European Committee for Standardization (CEN). These standards and guidelines provide requirements and guidance for the application, performance, and evaluation of nuclear NDT, and are used to ensure the consistency, reliability, and validity of nuclear NDT inspections and results.
