Disassembly Basin Walls and Floor

The K-, L-, and P Reactor Disassembly Basin walls and Boors provide the secondaiy liquid confinement fbr the fission products, fissile and target materials, product mat ials, and other radionudides contained in the fiiel and target assemblies, control rods, source rods, and miscellaneous irradiated reactor components. The walls and floors of the basms also s e as the primary confinement of approximately 3,400,000 gallons for K- and L-Reactor Disassembly Basins and 4,800,000 g ons of contaminated basin water contained in the P-Reactor Disassembly Basins. (See Section 2.3.2 of this BIO for further discussion of the K-, L-, and F-Reactor Disassembly Basin walls. and floors.)... 

The Disassembly Basin walls and floors are credited to some degree in the analyses of all postulated acddents fl>r providing confinement of contaminated basin water in a manner which minimizes its rdease to the environment The floors and wall are designed to withstand all scenarios except DBE and the dropping of a shipping cask. 

The K-, L-, and P Reactor Disassembly Basin walls and floors are also passive components. As such, the walls and floors are always available. The walls and floors are designed to provide leak-free confinment of basin water unless foe walls and/or floms are damaged during a DBE or shipping cask drop evoit.
