Use of electron linac for study of fission product and actynide diffusion through glass ceramic matrices
The diffusion of cerium and uranium was investigated in glass ceramic matrices obtained in the gasostat. For activation of isotopes ¹⁴⁰´¹⁴²Се and ²³⁸U the brake radiation from electrons of the linear accelerator was used. The threshold of detectability of elements was reached from 5 to 15 µg/g for...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The diffusion of cerium and uranium was investigated in glass ceramic matrices obtained in the gasostat. For activation of isotopes ¹⁴⁰´¹⁴²Се and ²³⁸U the brake radiation from electrons of the linear accelerator was used. The
threshold of detectability of elements was reached from 5 to 15 µg/g for a sample of the area 1 cm². The coefficients
of diffusion in the grain material and at grain boundaries were measured, and their values for the pressing temperature of 910°С and pressure 100~МPa were 3.5⋅10⁻⁹ cm²/s in the grain and 1.2⋅10⁻⁸ cm²/s at grain boundaries. |
