Project summary

Application of neutron radiation broadens essentially the capabilities of modem nondestructive methods of inspection due to high penetration depth in materials containing heavy elements as well as due to high sensitivity to hydrogen.

It is supposed to develop high resolution (better than 100 nm) neutron radiography method, to manufacture a prototype of a mobile neutron defectoscope and to experimentally prove its perspectives for industry and researches. The method and the device salient features are in using of a portable pulsed neutron generator, an electronic position-sensitive neutron detector, a personal computer and an appropriate software. That permits to carry out an object defectoscopy in operating and field conditions.

Application of ecologically clean radiation sources (neutron generators) considerably reduces needs in isotope and reactor sources, increases radiation and environmental safety.

Neutron image registration by an electron-optical detector has to increase defectoscope productivity up to 10 times in comparison with traditionally used photoplates. Presentation of information in a digital form provides application of advanced computer methods for data processing.

Defectoscope is aimed at:


- quality inspection of industrial goods (including objects with high thickness), made of metal, composite, glass, ceramics, etc.;
- inspection of the state of critical constructions in nuclear and thermal power industries, aircraft and rocket industries, gas-oil production;
- monitoring of processes in which hydrogen-containing materials are involved (corrosion, embattlement, seam, fuel combustion, greasing materials distribution);
- different defects detection - hidden cracks, corrosion, water or fuel accumulation;
- detection of materials used in nuclear weapons production: lithium-6, uranium, plutonium, etc.;
- scientific researches in nuclear physics, solid-state physics, material science, medicine.

Realization of the project in frames of conversion of special technologies will provide industrial enterprises and research institutes with high-informative apparatus for nondestructive inspection.

At present FI and VNIIA have sufficient scientific-technical background, technical base and experience Air production of modem high-technology installation - neutron defectoscope.
