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.
FLAC is numerical modeling software for advanced geotechnical analysis of soil, rock, groundwater, and ground support in two dimensions. This course is great for beginners are well as those wanting to brush up on basic skills.
Mr. Sylvain provides editorial and authorial input to Itasca software documentation.
