Spent Nuclear Fuel [SNF] Project Canister Storage Building [CSB] Final Safety Analysis Report [FSAR] Volume 1 [Section 1-3

Abstract

The U.S. Department of Energy (DOE) established the Spent Nuclear Fuel (SNF) Project to address safety and environmental concerns associated with deteriorating SNF presently stored under water in the Hanford Site K Basins, which are located in the 100 K Area near the Columbia River. Recommendations for a series of projects to construct and operate systems and facilities to manage the safe removal and storage of K Basins fuel were made in WHC-EP-0830, Hanford Spent Nuclear Fuel Recommended Path Forward, and its subsequent update, WHC-SD-SNF-SP-005, Integrated Process Strategy for K Basins Spent Nuclear Fuel. The integrated process strategy recommendations include the following steps: (1) Fuel preparation activities at the K Basins, including removing the fuel elements from their K Basins canisters; separating fuel particulate from fuel elements and fuel fragments greater than 0.25 in. in any dimension; removing excess sludge from the fuel fragments by means of flushing, as necessary; and packaging the fuel into multi-canister overpacks (MCOs); (2) Transportation of MCOs loaded with SNF from K Basins to the Cold Vacuum Drying Facility (CVDF); (3) Removal of free water by draining and vacuum drying at the CVDF in the 100 K Area; (4) Dry shipment of fuel from themore » CVDF to the Canister Storage Building (CSB), a new facility in the 200 East Area; and (5) Interim storage of the MCOs in the CSB until a suitable long-term repository is established. In addition, the CSB can also store Shippingport Pressurized Water Reactor Core 2 blanket fuel assemblies in a modified MCO container called the Shippingport spent fuel canister. The Interim Storage Area has been established adjacent to the CSB for storage of other non-defense SNF in above-ground dry cask storage containers.« less
