PINC Atlas – PWSCC/NDE Relational DatabaseDesign – Problem Statement
PINC Atlas – PWSCC/NDE Relational DatabaseDesign – Problem Statement
NDE relational database design problem: How can large volumes of NDE data be stored and used in NDE effectiveness calculations?Solution employed in the PINC Atlas:
Store high-level information in tables for important results (an estimate of NDE effectiveness or an inspection of a crack)Allow such records to reference collections of spreadsheets, documents, pictures, and presentationsLink to large volumes of data. Extract data to spreadsheets. Use spreadsheets, not query languages,for calculations.

PINC Atlas – PWSCC/NDE Relational DatabasePWSCC Morphology
PINC Atlas – PWSCC/NDE Relational DatabasePWSCC Morphology
NA 2 PWSCC Shows:Short, radial, discontinuous crack on the wetted surfaceLong, radial, discontinuous crack beneath the surfaceMultiple cracks on the machined buttering-to-annulus interface

PINC Atlas – PWSCC/NDE Relational DatabaseNDE Response Information
PINC Atlas – PWSCC/NDE Relational DatabaseNDE Response Information
Calibrated Eddy Current Response Distributions are being added to the Atlas database.
From PWSCC in nozzle 31 from NA 2From manufactured cracksFrom EDM notchesFrom fabrication flaws
Additional calibrated responses sought from field degradationSome response information will be gathered in the round robin of manufactured cracksResponse Distributions are important in detection theory
