Neutron Radiography and Imaging
Neutrons image materials that X-rays cannot, revealing hidden hydrogen-rich features and defects in dense assemblies.
Seeing what X-rays miss
X-rays are stopped by heavy elements and pass easily through light ones. Neutrons behave almost oppositely: they penetrate many dense metals but interact strongly with hydrogen. Neutron radiography therefore reveals features, such as sealed organic components, adhesives, corrosion, or trapped moisture, inside metal assemblies that X-rays render as solid blocks.
Defense-relevant inspection
- Inspect sealed assemblies non-destructively
- Detect corrosion and hidden moisture in metal
- Verify presence and condition of internal components
The source requirement
Neutron imaging needs a suitable neutron source and collimation. A steady 14 MeV source, moderated as needed, can support radiographic inspection as part of a broader neutron-service capability. This complements existing imaging tools rather than replacing them.
Kronos frames neutron imaging as one service in the breeder's neutron economy, described at a public, non-operational level.
Complementary imaging
Neutron and X-ray imaging are best used together, since each sees what the other cannot: X-rays outline dense metal while neutrons reveal light, hydrogen-rich material inside it. Combining both gives a fuller internal picture of a sealed assembly than either alone. As part of a neutron economy, radiographic inspection shares the same characterized source used for irradiation and analysis, which makes it an efficient addition to the service menu rather than a separate facility. Sharing one characterized source across imaging, irradiation, and activation analysis makes each capability an efficient addition to the service menu rather than a separate, standalone facility.
This page describes a design and simulation study, not a built machine. The breeder (Hyperion) begins construction Q2 2027; first-of-a-kind first tritium is targeted near 2030. No hardware net-gain is claimed before then.
