Scientists huddled in Las Vegas last week to discuss what could happen hundreds or thousands of years after dust settles on Yucca Mountain's nuclear waste containers.
While there is still much work to do, consultants to federal agencies found that corrosion on waste containers stemming from dust and water infiltrating the volcanic-rock ridge won't be significant for tens of thousands to hundreds of thousands of years.
