Recommendations for Critical Flaw Size Calculations (in Wolf Creek Advanced FEA Project)
By Peter C. Riccardella May 8, 2007 Summary of Key Issues from [1] (Reference list on last slide)
- Material Properties for Use in Evaluation
- Inclusion of Secondary Stresses EPFM vs. Limit Load
- Plot of data from Battelle/NRC Full Scale Pipe Tests on SS and A-600 indicates that Limit Load (ANSC) works well for all flaw types tested
- Comparison of Fracture Toughness (J-R Curves)
indicates Alloy 182 not si gnificantly less tough than tested materials
- DPZP screening criteria [2] adapted to complex
crack tests gives reasonable results Can be used to screen current analyses of A-182 for appropriate analysis type Limit Load (ANSC) Applied to Battelle/NRC Full Scale Pipe Tests [4, 5]0.00.51.01.52.02.53.03.54.00.0%10.0%20.0%30.0%40.0%50.0%60.0%70.0%80.0%90.0%CF(Pm+Pb)/SmComplexThru-wallSurfaceWOL (Surf)ANSC-A-600;complexANSC-SS;complexANSC-SS;thruANSC-SS, surfANSC-SS surf;Pm=9ksiPure Axial LoadTests w/ Pressure + Bending (large symbols)42" Pipe Definition of Various Flaw Types Tested [4]

Inclusion of Secondary Stresses
- Dynamic tests cited in [1] as reason for including secondary stresses not compelling
- Static tests with large complex cracks indicate
large displacements required prior to crack
instability many times larger than expected displacements due to thermal loadings in plants, including stratification Schematic of Compliant Load Complex Crack Pipe Test [4]

- Limit Load vs. EPFM -Apply DPZP Screening Criteria For DPZP > 1.0, use limit load (ANSC for actual flaw shape)For DPZP < 1.0, use limit lo ad with Wilkowski Z-Factor Correction
- Material Properties Use SS Base Metal Tensile Propertied (Flow Stress, Stress-Strain Curve)
- Secondary Stresses Overly Conservative to Include Full Value of Large
Stratification Moments in Surge Nozzle Limit Load Evaluations Include Piping Geometry of Typical Plant(s) to Determine
