The Hanford site has 149 single-shell tanks built as early as World War II storing waste until it is transferred to a limited number of tanks that better guard against leaks and then treated for ...
The system analyses rates of change in tank contents (i.e. leakage into or out of the tank). If a leak is found when operating on a single wall system, the product will always be released to the environment before the leak is detected. For tanks there are 2 subclasses of the system.
The Department of Energy has announced the transition to a new $45 billion contract over at least a decade to manage and treat radioactive waste in underground tanks at the Hanford nuclear site.
The tanks are oozing about 960 gallons a year into soil above groundwater that flows toward Columbia River. 2 Hanford tanks are leaking nuclear waste into the ground. Plan to deal with them settled
The Vit Plant will first process Hanford's low-activity waste liquids, starting as soon as 2023, as part of the Department of Energy's Direct-Feed Low-Activity Waste (DFLAW) approach. Under DFLAW, waste will be sent from the tank farms to the Vit Plant's Low-Activity Waste Facility for vitrification.
PNNL research helped scale a pretreatment method from laboratory testing to a fully operational tank-side cesium removal system that is installed alongside one of Hanford’s underground tanks.
The plant is being built to turn some of the 56 million gallons of Hanford radioactive waste stored in underground tanks, many of them prone to leaking, into a stable glass form for permanent ...
The 10-year contract covers work at the Hanford site tank farms, where 56 million gallons of radioactive waste are stored in underground tanks, and operation of the vitrification plant to treat ...
