| Popis: | The article presents the results of studying the density of steel 12Kh18N10T and the coefficient of thermal expansion TEC (α) in the temperature range from 100 to 850˚С. The measurements were carried out using a DIL-405 C dilatometer. Steel 12Kh18N10T will replace traditional TVEL cladding materials, which are made of zirconium material. The cladding made of steel 12X18H10T can be used as a Tolerant fuel. It is shown that the thermophysical properties and accurate dilatometric results of studies of steel 12Kh18N10T make it possible to use steel cladding in fuel assemblies of a VVER reactor. The article presents the results of comparison with similar data from the State Service of Standard Reference Data system. |
