Mechanical behavior of CBF-K canisters stored at CSA under internal gas pressure ()
In order to update the acceptance criteria of reactive metals in the Aube repository center (“CSA”, France) for low and intermediate-level short-lived radioactive waste, Itasca teamed with EGIS to study the mechanical behavior of graveled (OG) [1] and concreted (OB) structures containing concrete or steel canisters.
Calibration of a Blasting Model for an Open Pit Mine in Chile ()
The purpose of the study was to provide technical support to the blasting area of an open pit mine. The problem analyzed is related to the non-conformity of the design berms observed in the mine and the need to understand the relative contribution of the structural condition of the rock mass and the design of the blasts to the final situation of the affected benches.
Rock Stabilization at Pompeys Pillar National Monument ()
Pompeys Pillar National Monument is a 200-foot-high sandstone outcrop containing hundreds of prehistoric and historic features, including William Clark’s signature, inscribed on the sandstone rock in 1806. The U.S. Bureau of Land Management asked ITASCA to assess the stability of the Signature Block and to evaluate remedial measures.
Spruce Tree House Arch Stabilization, Mesa Verde National Park ()
Mesa Verde National Park, located in southwestern Colorado, is the site of the 800 year old Spruce Tree House Alcove. The nose of the alcove contains a thin arch delineated by a persistent curved crack (called Richardson crack). Rockfalls from the arch and adjacent rock surfaces have shown the need for a new assessment of arch stability and additional support efforts.
Conceptual EGS Reservoir Design with Natural and Induced Fractures ()
ITASCA was tasked by Sandia National Laboratory to simulate the proposed USDOE Fallon FORGE site reservoir, which included induced and natural fractures, to inform different conceptual designs for well geometries and stimulation strategies.
