Zone Item Sheet 1 of 2 C2 PART LIST SAFETY Item 12 A < Downgraded based on guidance provided in NUREG/CR6407>

CLASSIFICATION LUG B Justification: The J Hook Connectors are used to secure the Cask Assembly within the Impact Limiter Assemblies and serve as an operational support function. These have a minor impact on safety. Their failure or malfunction would not significantly reduce the packaging effectiveness and would not likely create a situation adversely affecting public health or safety. Due to the redundancy of the J Hook Connectors and the Versatileend Webbing Assemblies (AOS025 only), these components can be classified as Safety Classification B.

A3 PART LIST SAFETY Item 18 B < Downgraded based on guidance provided in NUREG/CR6407>

CLASSIFICATION TRUNNION C COVER SCREW Justification: Trunnion Cover Screws are only used to secure the Trunnion Cover to the Trunnion. As failure will not allow breach of the containment or shielding, Safety Classification C is an appropriate designation for this part.

A3 PART LIST SAFETY Item 20 B < Downgraded based on guidance provided in NUREG/CR6407>

CLASSIFICATION THREADED C INSERT Justification: Threaded Inserts are only used to secure the Trunnions to the Cask Assembly using the Trunnion Screws for lifting purposes. Threaded Inserts have a very limited safety function during transportation; and failure will not allow breach of the containment or shielding, Safety Classification C is an appropriate designation for this part.

A3 PART LIST SAFETY Item 22 A < Downgraded based on guidance provided in NUREG/CR6407>
