Yucca fault line might spring surprise (LVRJ)

Letter, maps suggest it’s not where scientists had thought it was

LAS VEGAS–Bore hole drilling operations at the planned Yucca Mountain nuclear waste site have turned up preliminary evidence that an earthquake fault line passes beneath the place where project officials want to build concrete pads for storing thousands of tons of highly radioactive spent fuel.

A letter and maps from the U.S. Geological Survey obtained last week by the Review-Journal show that the Bow Ridge fault passes directly beneath the footprint of a pad where spent fuel canisters would age or cool down before they are entombed in a maze of tunnels inside the mountain, 100 miles northwest of Las Vegas.

Rock core samples extracted by drill rigs about 250 feet below the surface indicate that the fault is hundreds of feet east of where scientists had thought it was.
