Bechtel announced on Monday that it had successfully completed the first set of test glass pours into a storage container designed to hold vitrified radioactive and chemical waste.

Only about 10% of the tank waste is expected to be high-level waste. Hanford site workers filled a waste container with glass for the first time at the vitrification plant for the first time.
