HI-SAFE®
Holtec’s Non-Fuel Waste Storage System
HI-SAFE offers a safe and cost-effective solution for the on-site storage of non-fuel waste generated during the operation and decommissioning of commercial nuclear power plants. This versatile module is designed for both storage and transportation of Class B, Class C, and Greater-Than-Class-C (GTCC) waste, including highly activated metal components resulting from reactor operations and decommissioning activities.

The HI-SAFE Storage System utilizes the same ancillary equipment employed for loading Holtec’s HI-STORM spent nuclear fuel dry storage system. This compatibility allows facilities to capitalize on existing expertise and trained personnel to ensure an efficient and successful HI-SAFE loading campaign. With a 290-cubic-foot internal volume, the Non-Fuel Waste Canister (NFWC) offers the industry’s highest capacity for storing high-activity radiological waste. The steel-concrete-steel HI-SAFE overpack delivers exceptional biological shielding and structural protection, while the NFWC itself can be transported using the same methods as Multi-Purpose Canisters that contain used nuclear fuel.
