# Nuclear fuel transport: Overview

Moving the world's most energy-dense fuel safely

Source page: https://www.materialinsights.org/energy/e_nuclear_transport/overview/

Moving the world's most energy-dense fuel safely What this tile covers Licensed shielded containers for fresh fuel, and heavy casks for spent fuel. Share of use 5.2% share of world energy carried (2024)

Share of world total energy supply (592 EJ in 2024, Energy Institute Statistical Review 2025, physical energy content) carried at least once by this mode; overlaps allowed, so shares do not add to 100 (calculated) Nuclear supplied 30.74 EJ in 2024, counted as reactor heat; all of its fuel travels from mine, conversion and enrichment to reactors in licensed containers.
