Problems solved by technology

The expansion of the cladding is accompanied by the axial expansion and contraction of the cladding. At the same time, due to the thinner thickness of the fuel cladding, the expansion of the cladding makes the cladding bear excessive stress and cause the cladding to explode

Abstract

The invention discloses a reactor cladding blasting experiment system and an experiment method. The system comprises a top gas chamber, a heating furnace, a bottom gas chamber, an inert gas pressurization unit, a water cooling unit, a heating unit, a vacuum unit and an atmosphere supply unit. The blasting experiments of the cladding in different environments, such as inert gas, water vapor, air, vacuum, etc., are achieved through the coordinated work of all the parts in the system, the blasting data of the cladding in different environments can be provided, and powerful data support is provided for the establishment of a cladding blasting criterion model.

Description

technical field [0001] The invention relates to the field of reactor safety, in particular to a reactor cladding blasting experimental system and an experimental method. Background technique [0002] The fuel element cladding is the first barrier of the reactor radioactive material, which can contain more than 90% of the fission products. The integrity of the fuel cladding is of great significance to avoid the leakage of radioactive materials in normal operation and accident conditions. In a coolant loss accident, the continuous increase in fuel cladding temperature and the release of fission gases lead to an increase in the internal pressure of the cladding, causing cladding deformation. The expansion of the cladding is accompanied by the axial expansion and contraction of the cladding. At the same time, because the thickness of the fuel cladding is thin, the expansion of the cladding makes the cladding bear excessive stress and cause the cladding to burst. [0003] The s...
