Is An Institute for the Study of High-Level Radioactive Waste Disposal Needed in Southern Nevada?
This paper examines key questions about the need for a formal institute that would study storage and disposal concepts for high-level radioactive waste (HLW) in the United States and throughout...

Modelling Gas Migration Experiments in Repository
In response to concerns over the possibility of hydrogen gas generation within an underground repository for high-level radioactive waste, and its implications for repository safety, a...

Carbon Isotopic Data from Test Hole USW UZ-1, Yucca Mountain, Nevada
Rock-CO2-gas analyses in test hole USW UZ-1 at Yucca Mountain indicate that gas movement in the unsaturated zone is likely through a dry-fracture...

Carbon-14: Some Evidence of Migration and Experiments on Immobilisation
Carbon-14 that is produced in nuclear reactors by reactions on C, N and O is one of the most biologically dangerous nuclides that are subject to global dispersion (H-3, 85-Kr, 129-I)....

Diffusion of Carbon Dioxide Through Layers of the Unsaturated Zone at Yucca Mountain
The estimation of diffusive transport of gases through tuffs is important in order to asses the Yucca Mountain as an environmentally safe and acceptable repository for spent fuel and high-level...

An international survey and review is being conducted on the latest developments in modelling of near-field performance, with particular emphasis on the conceptual and mathematical models...

AREST: The Next Generation
Simple mass transport models using constant boundary conditions at the waste form surface and at the host rock boundary do not always results in realistic predictions of the performance...

WAPPA Modeling of Post-Emplacement Performance of the AECL HLNW Package
Environment Canada (EC) is anticipating, in the near future, a review of the EIS document released by AECL which addresses the performance of their HLNW disposal concept. This paper presents...

Scenario Development for Performance Assessment?Some Questions for the Near-Field Modelers
In an attempt to achieve completeness and consistency, the performance-assessment analyses developed by the Yucca Mountain Project are tied to scenarios described in event trees. Development...

High-Level Radioactive Waste Transportation Operations and Routing Regulations: Friend or Foe?
The process of shipping high-level wastes and its equivalents is a highly-regulated endeavor. Safety requires consistency and rationality thereby giving way to Federal preemption in the...
