AT NEVADA..............SITE CONDUCTS SECOND 'SOURCE PHYSICS EXPERIMENT1

摘要

The National Nuclear Security Administration has conducted a second "Source Physics Experiment" at the Nevada National Security Site designed to improve the agency's understanding of low-yield nuclear explosions and enhance nuclear test monitoring capabilities around the world. The experiment is the second in what will be a series of eight "underground, fully-coupled, high-explosive" tests, according to the NNSA. The test was conducted in a small chamber 150 underground at the test site, where 2,200 pounds of TNT was detonated to send shock waves through the thick granite rock formations at the site. It was much larger than the first Source Physics Experiment in May that used only 220 pounds of chemical explosive.
