Implementation of neutron radiography in the MNSR Low Power Research Reactor

Neutron radiography is an unique, advanced and useful non-destructive test method in various industries and researches. Nuclear reactors are powerful and stable neutron sources for the neutron radiography system. In this research, the MNSR research reactor has been used as a neutron source for a neutron radiography system, and its neutron beam parameters have been evaluated. Also, using the direct conversion method and the gadolinium converter, the neutron image was obtained in its neutron beam and the image quality of the neutron was evaluated using the standard image quality standard ASTM-E545. The results of the measurements show that the neutron flux of the system in the maximum reactor power is equal to 3×105 n.cm-2.s-1 and the collimation ratio is 100. Image quality evaluation also showed that the obtained image has a V quality category based on the ASTM-E545 standard.
