Long-term storage of spent fuel is critical to the nuclear energy industry. The Swedish Nuclear Fuel and Waste Management Company (SKB) is developing an approach for the storage of spent nuclear fuel in an underground repository in competent crystalline rock. In order to better understand the spalling damage process, an in-situ test involving the drilling of two boreholes was performed in Äspö diorite at SKB’s underground hard rock laboratory in Äspö. Tests and monitoring were performed on the pillar that separated the boreholes. In order to further investigate the damage process, Itasca performed numerical modeling using PFC3D and FLAC3D.
The 56th US Rock Mechanics / Geomechanics Symposium covers all aspects of rock mechanics, geomechanics, and rock engineering.
Dr. Ghazvinian specializes in geomechanics of brittle rocks. He offers expertise in continuum and discontinuum modeling of underground excavations prone to brittle fracturing and spalling. He has experience in application of numerical models to sequencing life of mine simulations and predicting potential seismic hazards in deep underground excavations.
