The last massive door designed to act as a radiation shield has been delivered to the Hanford vitrification plant.
It weighs 102 tons and will be installed in the High Level Waste Facility, where high level radioactive waste left from weapons plutonium production will be turned into a stable glass form for disposal.“Receipt of the last of the shield doors represents a significant milestone in progress on the project, and they are an integral part of the plant’s safety infrastructure,” said Joe St. Julian, Bechtel National area project manager. Bechtel is designing and building the vit plant.
The plant has more than 100 nuclear-quality shield doors, ranging from three to 119 tons. They will provide radiation protection and maintain contamination boundaries during plant operations.The recently delivered shield door is made of carbon steel and measures more than 15 feet wide, 36 feet tall and 7 inches thick. It will be installed in the area of the High Level Waste Facility that holds the melters.
