For the generic disposal design, how many fuel assemblies per canister, and how many canisters fit into the waste disposal section of one borehole?

Each canister contains a single spent fuel assembly from a Pressurized Water Reactor (PWR). A 1 km-long disposal section holds about 150 canisters. An array of 10 parallel disposal sections holding a total of 1,500 PWR assemblies would accommodate the waste being produced by a 1,000 MWe nuclear power plant in 30 years.
