Measurements have exceeded 5,000 for sizing and 14,000 for piping detection and length sizing. Both piping and bolting statistics provide a significant database of inspection reliability information, which can provide a strong technical justification for future applications. Phase II of the PDI program is addressing important problems that could significantly the cost and effectiveness of the US performance demonstration approach. These include the Nozzle inner-radius examination from the outside surface, nozzle to shell weld examinations and dissimilar metal welds. A cost effective method of demonstration and A uniform implementation across the industry.
Reasonable solutions are possible to achieve effective yet cost efficient demonstrations.
Overly conservative flaw size and reliability input requirements may frustrate the demonstration process and will certainly result in unreasonable costs and will likely result in disillusionment of all parties concerned.
