In New Mexico, the Los Alamos National Laboratory, the main nuclear weapons lab in the United States, has been shut down for a second day as a massive wildfire approaches the facility. The anti-nuclear watchdog group, Concerned Citizens for Nuclear Safety, says the fire now appears to be about 3.5 miles from a dump site at the lab where as many as 30,000 55-gallon drums of plutonium-contaminated waste are stored in fabric tents above ground.
