Environmental gases,permeability,and thermal conductivity tests at borehole ONC 1,Yucca Mountain,Nevada

摘要

The purpose of the gas sampling and testing at borehole ONC 1 are to: centre dot Estimate the ages of the gases in the vadose zone in ONC 1 and their relationship with the ages of the water obtained from other boreholes at yucca Mountain that could help evaluate the percolation and recharge at the site. centre dot Understand the transport mechanism governing gaseous migration in the vadose zone at this site. centre dot Evaluate the effect of tunneling on the repository horizon.
