United States Nuclear Regulatory Commission Program for the Inspection of Nickel Alloy Components (PINC) 8th Meeting February 5-6, 2007 Rockville, Maryland, USA Carol E. Moyer, Materials Engineer US NRC Office of Nuclear Regulatory Research 01-415-6764 cem3@nrc.gov

Objectives for PINC Cooperative Research Project

• Document the range of locations and crack morphologies associated with PWSCC and observed NDE responses

• Fabricate / obtain representative NDE mock-ups with flaws to simulate tight PWSCC cracks

• Identify and quantitatively assess NDE methods for accurately detecting, sizing and characterizing tight cracks such as PWSCC

• Incorporate findings from other ongoing PWSCC research programs, as appropriate 5-6 February 2007 PINC-8 2

Project Organization

• Task 1 - Morphology Atlas (TG-Atlas)

- Compile existing work on crack morphology of PWSCC

- Correlate with NDE data, when available

- Develop an electronic Atlas (database) of NDE and metallography information

- Perform new NDE, fractography, metallography

• Task 2 - NDE Technology Assessment (TG-NDE)

- Round Robin of NDE techniques on PWSCC and simulated cracks

- Assess techniques to detect and size cracks

- Assess techniques to manufacture test blocks

- Consider relevant materials, geometries

- Integrate findings for regulatory application, process qualification 5-6 February 2007 PINC-8 3
