![]() ![]() (The MCO remains within the same shipping Cask from the time it enters the basin to receive its SNF payload until it is removed from the Cask by the CSB MCO handling machine.) The CVDF subproject acquired the required process systems, supporting equipment, and facilities. The MCO will be sealed, leak tested, and then transported to the CSB within a sealed shipping cask. The MCO will be evacuated to a pressure of 8 torr or less and backfilled with an inert gas (helium). The cold vacuum drying process involves the draining of bulk water from the MCO and subsequent vacuum drying. water from the MCOs to reduce the potential for continued fuel-water corrosion reactions. ![]() Access and egress is provided by the main entrance to the 100K inner area using existing roadways. The site area required for the facility and vehicle circulation is approximately 2 acres. The CVDF is located within a few hundred yards of the basins, southwest of the 165KW Power Control Building and the 105KW Reactor Building. Removal of free water is necessary to halt water-induced corrosion of exposed uranium surfaces and to allow the MCOs and their SNF payloads to be safely transported to the Hanford Site 200 East Area more ยป and stored within the SNF Project Canister Storage Building (CSB). Department of Energy Hanford Site in Southeastern Washington state. The MCOs contain metallic uranium SNF that have been removed from the 100K Area fuel storage water basins (i.e., the K East and K West Basins) at the US. The mission of the Spent Nuclear Fuel (SNF) Project Cold Vacuum Drying Facility (CVDF) is to achieve the earliest possible removal of free water from Multi-Canister Overpacks (MCOs). ![]()
