LAS VEGAS (AP) - U.S. and British government scientists performed an underground nuclear experiment, short of a nuclear blast, at the Nevada Test Site this week, the National Nuclear Security Administration said.
The experiment on Tuesday involved detonating high explosives around radioactive material in a vault about 1,000 feet below ground at a remote part of the desert testing range 85 miles northwest of Las Vegas.
No radioactivity was released in the subcritical experiment, said Nancy Tufano, spokeswoman for Bechtel Nevada, a contractor at the nuclear security administration in North Las Vegas.
