ENIQ POSITION on Inspection Qualifications of Non-Nuclear Island Components

Original language description

The ENIQ Methodology and accompanying ENIQ recommended practices provide a framework for the qualification of Non-Destructive Testing (NDT) systems. The aim is to gather evidence in the form of complete Technical Justifications (TJs) or practical assessment results that demonstrate the NDT system, including the inspection procedure (IP), has been designed to achieve the objectives and can meet them reliably. The ENIQ Methodology has been widely adopted for highly critical nuclear primary system inspections where the component failure has significant consequences. It has rarely been utilised for other industries or nuclear balance-of-plant components of lower safety significance due to perceived costs and timescales. It is the purpose of this position paper to show how the ENIQ framework can be applied in a cost-effective manner and bring benefits to other areas. The Research Centre Rez (CVR) of the Czech Republic has been working to show such benefits with an initial focus on fossil power plant inspections. ČEZ fossil power plants were used as a case study with five non-destructive inspections and one diagnostic inspection method qualified by CVR in accordance with the ENIQ framework. Although the qualified inspection methods are for fossil power plants, they serve as examples of the suitability of application of the ENIQ Methodology to qualify inspections in numerous other areas outside of the nuclear primary systems.

Technical parameters

The objective of inspection qualification is to provide assurance, or confidence, that an inspection reliably achieves the objectives defined within the input information for the inspection, or inspection datasheet. The importance of inspection reliability and therefore the effort and resources typically applied to demonstrating reliability, is dependent on: 1) The role of that inspection within the component and/or plant safety case. 2) The safety risk posed by the failure of that component, where risk is expressed based on the combination of the likelihood and consequence of the failure (see reference [2] for further details). 3) The regulatory or statutory requirements applicable.

Economical parameters

By applying a graded approach to qualification, the effort and resources applied to achieve confidence that the inspection will be capable of meeting its objectives can be targeted for greatest safety benefit.
