The Holtec International Storage Module Flood and Wind (HI-STORM FW) system is Holtec International’s USNRC- licensed, highest capacity canister-based system for storage of spent nuclear fuel (NRC Docket No. 72-1032). The design details of the HI-STORM FW System have been guided by two decades of research and technology development by Holtec International. The canister, known as the multi-purpose canister (MPC), is licensed by the USNRC for transportation in the HI-STAR 190 transportation overpack (NRC Docket No. 71- 9373). Holtec’s dry cask storage technology is predicated on providing our clients with an integrated solution for all stages of spent fuel management in a safe and secure manner that limits the dose to the public and employees. In use at over 60% of the operating nuclear units in the United States, there are more than 1,200 Holtec dry storage systems loaded.
