Modeling of the Ventilation for Emplacement Drift Re-Entry and Rock Drying
Different ventilation scenarios were analyzed for a hot repository with a 114 kw/Acre heat load, to determine the time required to cool a drift to the point where the temperature of the...
Large-Scale in Situ Heater Tests for Hydrothermal Characterization at Yucca Mountain
To safely and permanently store high-level nuclear waste, the potential Yucca Mountain repository site must mitigate the release and transport of radionuclides for tens of thousands of...
Emplacement Drift Temperature Reduction by Cooling Enhancement and Ventilation
The application of cooling enhancement in a short vertical container emplacement layout is analyzed. Two 25 m-long heat pipes upward oriented at 45 degrees are installed at each emplacement...
The Analysis of Horizontal Cooling Enhancement for Nuclear Waste Container Emplacement
This paper presents a novel method for distributing the heat generated by waste containers emplaced in the proposed high-level nuclear waste site at Yucca Mountain, Nevada. The method...
