Impact of the New IAEA Shielding Recommendations on Spent Fuel Storage and Transport Cask Performance

According to the latest IAEA recommendations (2012, SSR-61), shielding analyses under routine transport conditions have to be performed considering loading plans with the maximum allowed radioactive contents. In parallel, regulators of storage now request the definition of generic loading plans.Thus, cask designers are facing the challenge of implementing a method to define maximum generic loading plans and to avoid a performance decrease on new cask design or cask license renewal.
