The Department of Energy has released the fourth chapter in its video series explaining the Hanford nuclear reservation from its beginnings to current environmental cleanup.
The fourth chapter, an eight minute video, focuses on the 56 million gallons of radioactive waste left from the past production of weapons plutonium. The waste must be removed from leak-prone underground tanks to prevent further leaks.
The video also covers how tank waste will be turned into a stable glass form at the $12.2 billion vitrification plant under construction.
The video is posted at 1.usa.gov/x9vLui on the internet and also will be screened by speakers requested from the Hanford Speakers Bureau, which may be contacted by emailing HSB@rl.gov.
