AREVA procedure54-UT-I114-000 (Reference 10.6) was used for the blind demonstration and modified toaddress lessons learned during the demonstration (i.e., 54-UT-i114-001 -Reference 10.7).The blind demonstration included the scanning and data analysis of an OTCP and ITCP lidweld mockup containing a number of controlled weld manufacturing flaws that were not madeknown to those performing the analysis (in accordance with reference 10.6). Scanningincluded the flaw detection phase where flaws that exceeded the recording threshold of theprocedure were recorded for further characterization using the sizing scans called for by theprocedure. Two separate data analysts participated in this demonstration, each workingindependently using the same governing procedure (reference 10.6).A synopsis of the results are listed in Table 9-1. The full report of the demonstration iscontained in Reference 10.5. The probability of detection (POD) was calculated to be 97%.One false call was reported. The flaw sizing accuracy (length and through wall (height) -(TWS) in inches) was calculated for each analyst in accordance with reference 10.3. Theresults presented in Table 9-1 are separated by each analyst and each weld.TABLE 9-1ANALYST "A" RMS ANALYST "B" RMSLength RMS Outer Lid Weld 0.110" Length RMS Outer Lid Weld 0.053"Length RMS Inner Lid Weld 0.118" Length RMS Inner Lid Weld 0.096"TWS RMS Outer Lid Weld 0.051" TWS RMS Outer Lid Weld 0.043"TWS RMS Inner Lid Weld 0.035" TWVS RMS Inner Lid Weld 0.040"Combined Length Sizing RMS 0.112" Combined Length Sizing RMS 0.077"Combined TWS Sizing RMS 0.043" Combined TWNS Sizing RMS 0.041"Based on the results of the blind demonstration, the procedure performance can be expressedas the average of the result achieved by each analyst.
