HI-STAR 100

HI-STAR 100 is the industry’s first dual purpose (storage and transport) cask. At present, it is limited to transporting canisterized high level waste (used nuclear fuel) only. A short version labelled HI-STAR HB is also licensed by the NRC. Canister is visible in the cutaway perspective view.

HI-STAR 190

HI-STAR 190 is the industry’s most heavily shielded cask capable of transporting every canister type currently in use at US nuclear plants with minimum dose.

HI-STAR 180

HI-STAR 180 is a dual-purpose cask with the capability to store/transport high burn-up and MOx PWR fuel. This cask does not contain an MPC and uses two independent lids for double containment.

HI-STAR 180D

HI-STAR 180D is a smaller ID and taller version of HI-STAR 180. Like HI-STAR 180, “180D” uses Metamic-HT for its basket to enable high heat rejection rate and a double lid construction to provide double containment.

HI-STAR 330

HI-STAR 330 (also called HI-STAR ATB-1T) is industry’s largest cask for transporting non-fissile waste and activated metal. HI-STAR 330 features a robust stainless-steel body and a heavy lid engineered to provide rapid opening and closing capability to minimize crew dose.

The trunnions in HI-STAR 330 are of collapsible type (a Holtec invention); the cask meets all requirements of 10CFR71 and IAEA standards without an impact limiter package.

HI-STAR 80

HI-STAR 80 has the highest heat rejection capacity of any cask in Holtec’s fleet (>60kW). The cask features a Metamic-HT basket and highly conductive external fins.

The basket is visible in the cut away view.

HI-STAR 60

HI-STAR 60’s loaded weight is approximately 60 tons which makes it the only cask for light water reactor fuel shippable by truck in Holtec’s fleet at this time. It features a stainless-steel fuel basket “poisoned” with Metamic (classic) neutron absorber panels for reactivity control. The storage capacity is 12 PWR assemblies.

HI-STAR 63

HI-STAR 63 is truck weight cask expressly engineered for fuel produced by Canadian-origin reactors. A number of HI-STAR 63 are in service at the Wolsong nuclear plant in Korea.
