Amendment No. 10 revises the CoC for the HI-STORM FW dry storage system to incorporate several enhancements including the introduction of the HI-STORM FW Extended Configuration, adoption of a methodology for developing site-specific loading patterns with higher allowable heat-load limits, incorporation of a radiological fuel-qualification methodology, reduction of minimum cooling-time requirements for certain canister models, and refinement of missile-impact analysis methodology. The amendment also includes a minor editorial clarification. Comments on the proposed rule are due by August 24, 2026.
