Inspection qualification is the term currently used to describe the process of independent assessment of a specific non-destructive test to ensure that it is capable of meeting its objectives. Such activities carried out on the Sizewell B reactor inspections were referred to as validation. In the USA, the term performance demonstration is used, though this is increasingly being reserved for the part of the assessment which uses practical trials, with qualification being used, as elsewhere, when the assessment process involves assembling evidence for the efficacy of an inspection from a wider variety of sources. Most qualification activity to date has been focused on nuclear plant because of the safety implications of nuclear plant failure and also because it is here that the cost of the qualification itself is in proportion to the cost of the plant and the consequences of failure. This paper reviews worldwide practice and experience in the qualification of ultrasonic inspections of nuclear components over the past two decades. In general, qualification has been applied to in-service inspections; however, this paper includes consideration of the application of qualification to manufacturing inspections. To date, ultrasonic inspection is the inspection method to which most qualification activity has been devoted. However, the qualification principles discussed are equally applicable to the qualification of other inspection methods.
