New Plateaus in Dry Storage and Transport Technologies
We are pleased to report that the license application to store the NUHOMS 24PT1-DSC canister in the HI-STORM UMAX subterranean storage system has been submitted to the U.S. NRC on schedule, as announced previously in this news bulletin (HH-31.09). The submittal presents a robust safety case for the processes for extracting the dry shielded canister from its horizontal module, up-righting and installing it in the HI-STORM UMAX’s subterranean cavity. As expected, change in the storage configuration from the horizontal NUHOMS to the vertical HI-STORM UMAX improves every metric of safety and security for the fuel which should help expedite NRC’s certification. The unavailability of proprietary design information from the canister’s designer, Areva, did not prove to be much of an impediment in the safety analysis effort. In due time, Holtec plans to submit all remaining canister types supplied by others that are presently in use around the U.S. for transfer to the HI-STORM UMAX. The object of this licensing campaign is to make it possible to store all U.S. commercial fuel at our planned Eddy-Lea alliance-sponsored HI-STORE CISF (consolidated interim storage facility) in Southeast New Mexico using a common storage system and a single type of ancillary equipment, to minimize human error.
