High-Level Radioactive Waste Management

Deep Isolation, founded by Elizabeth and Richard Muller, aims to use horizontal borehole drilling tech to bury nuclear waste in long, thin canisters.

Thousands of tanks and troops rumbled into the forested Chernobyl exclusion zone in the earliest hours of Russia's invasion of Ukraine in February, churning up highly contaminated soil from the site of the 1986 accident.

Here in the dirt of one of the world's most radioactive places, Russian soldiers dug trenches. Ukrainian officials worry they were, in effect, digging their...

An anonymous reader shared this report from the Mercury News: After a year of fastidious planning, a microscopic sample of the ultra-rare radioactive element berkelium arrived at a Berkeley Lab. With just 48 hours to experiment before it would become unusable, a group of nearly 20 researchers focus...

Scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) have prepared an organometallic complex from 0.3 milligrams of berkelium-249.

Today, more than 130 concrete casks containing dangerous levels of radiation are stored at Trench 94. In the next 20 years, more than 50 casks will be added.

Radiation exposure remains a devastating hazard to human health, and a poignant reminder that nuclear disasters have lasting consequences.

Experts are divided on just how bad the accident could have been.
