Zorita Materials Testing May 22, 2019 NRC-Industry Materials Exchange Meeting Matt Hiser, Sri Rao, and Rob Tregoning, USNRC The 1 views expressed in this presentation are those of the authors, not necessarily those of the U.S. NRC.
NRC Perspective on Zorita Materials Testing
- International cooperation made the ZIRP program highly cost efficient for members
- EPRIs role in leading and managing the ZIRP program is greatly appreciated
- Zorita materials have provided important data at higher fluence levels on highly representative LWR-irradiated reactor internals materials D fluence and temperature analyses increase the value by allowing the results to be put in proper context of the aging conditions seen
- Zorita materials testing data increases knowledge of stainless steel behavior at higher fluences
- Enabled additional research on Zorita materials by EPRI, NRC, and Halden
- Zorita weld testing funded by EPRI and NRC
- Crack growth tests on Zorita specimens at Halden
- Zorita materials testing at Argonne National Lab (ANL) funded by NRC
- Planned further irradiation of Zorita welds through Halden 2
Zorita Materials Testing at ANL
- Through cooperation with EPRI, NRC has acquired specimens of Zorita materials for testing at ANL
- Testing and characterization include:
- Crack growth rate and fracture toughness testing to assess response as a function of fluence
- Fractography and microscopy to correlate microstructural features of irradiation damage to observed behavior
- A technical paper describing research activities through April 2019 will be presented at the 2019 Environmental Degradation conference 3
