“…The same is true with respect to granite when fractures allow the intrusion of basinal brines. Salinity is critical, because high salt concentrations reduce the corrosion resistance of the copper shell around the waste container (Schwartz 1996(Schwartz , 2008.…”

Potential groundwater contamination above the one-time candidate repository for high-level nuclear waste in the Columbia River Basalt (CRB), USA, is evaluated in a flow-transport model with 260,895 elements for a period of 1 million years. The hydrogeologic database originates from the Basalt Waste Isolation Project, which ended in 1987, giving way to the Yucca Mountain project. The CRB data have been scanned recently with the object of finding a storage site for natural gas and a sequestration site for CO 2. However, the impact on the nuclear issue in the USA or other countries with similar large floodbasalt provinces has never been evaluated since the suspension of the project. The peak radioactive dose predicted for a potential repository in the CRB is at least eight orders of magnitude lower than the US generic regulatory limit (0.15 mS/a) even for the most pessimistic scenario.

“…Native copper is present as natural occurrence in the Earth's crust. The largest deposits are located on the Keweenaw Peninsula of Michigan, where they have been mined to a depth of 2.2 km (Schwartz, 1996). These deposits formed one billion years ago at temperatures of 100-200°C.…”

“…In other parts of the world, potential repositories are located below the water table (Schwartz 1996(Schwartz , 2008. The unsaturated zone precludes the protection of the metallic waste container by bentonite because the clay minerals would dehydrate and lose their isolating properties; thus, an entirely metallic barrier system has to be used.…”

A novel CO 2 sequestration project at Wallula, Washington, USA, makes ample use of the geoscientific data collection of the old nuclear waste repository project at the Hanford Site nearby. Both projects target the Columbia River Basalt (CRB). The new publicity for the old project comes at a time when the approach to high-level nuclear waste disposal has undergone fundamental changes. The emphasis now is on a technical barrier that is chemically compatible with the host rock. In the ideal case, the waste container is in thermodynamic equilibrium with the host-rock groundwater regime. The CRB groundwater has what it takes to represent the ideal case.
