HI-STORM UMAX

We are pleased to announce that Holtec International and Hitachi-GE Nuclear Energy, Ltd. have executed a Memorandum of Understanding to introduce and deploy Holtec’s canister-based dry storage and transport technologies for managing spent nuclear fuel in Japan.

We are pleased to announce the completion of the design and safety analysis effort to enable the NUHOMS 24PT1-DSC canister to be up-righted and stored in the HI-STORM UMAX subterranean storage system in the vertical orientation. Analyses using NRC-approved simulation methods show that various safety margins either remain the same or are increased when the canister is translocated in HI-STORM UMAX. This effort was undertaken to unify the storage of all canister types in Holtec’s ultra-safe consolidated interim storage facility, known as HI-STORE, at the proposed ELEA site in New Mexico. Its successful execution opens the path to store all of the nation’s used fuel and other high level waste in a single inaccessible-to-terror configuration. Of course, this work can also be used to move a stored canister from NUHOMS to HI-STORM UMAX at an existing ISFSI for improved aging management, reduced accreted dose or security enhancement purposes. The principal ancillary needed to make the transfer from the horizontal to vertical storage is the “Canister Handling Apparatus” (perspective views shown below) designed to effectuate safe canister handling evolutions with ALARA.
