HI-TRAC

The HI-STORM 100 System utilizes the HI-TRAC transfer cask for transporting the MPC from the spent fuel pool and for inter-cask MPC transfer required for on-site storage and off-site transport. A transfer cask is indispensable for implementing an independent spent fuel storage installation MPC loading in a HI-STORM 100 system and for future off-site shipment.

Key Operational Features

The HI-TRAC System, engineered to be fully compatible with the HI-STORM 100 and HI-STAR 100 overpacks, fulfills several key operational needs.

Smallest possible cross-sectional area to permit placement in tight-cask spaces in many pools

Flexibility in the design, such that sites which do not have more than 100-ton lifting capacity can be defueled using HI-TRAC.

Maximum protection against contamination of the MPC’s external surface.

To deal with the crane lifting capacity limitations at many plants, HI-TRAC has been licensed in two designs: HI-TRAC 100 and HI-TRAC 125, with 100 and 125 denoting the the maximum weight of the loaded HI-TRAC in tons during its lifting and handling operations.

HI-TRAC 100 and HI-TRAC 125 are physically identical except that the latter, due to its greater mass, provides more shielding. HI-TRAC 100 and HI-TRAC 125 both accommodate the standard MPC (containing up to 24 PWR or up to 68 BWR spent fuel assemblies). The HI-TRAC transfer cask provides optimal shielding of the fuel housed in the MPC to minimize personnel exposure during handling and MPC closure operations.

The HI-TRAC transfer cask is designed and fabricated to allow vertical handling of the loaded HI-TRAC while meeting the heavy-lifting requirements of NUREG-0612 and ANSI N14.6. The HI-TRAC is designed to interface with either the HI-STORM storage module or with the HI-STAR dual purpose overpack. The HI-TRAC system is designed to transfer the loaded MPC within the fuel storage building or at the storage pad. This assures that canister transfers for off-site transport can be completed without requiring reactor handling facilities (therefore, returning to the reactor building is not required).
