AP23489790 " Investigation of water vapor interaction with beryllides of different grades at critical and supercritical water vapor parameters "

Relevance

The relevance of the project is due to the need to study the behavior of structural materials in a high-temperature water environment typical of advanced generation IV reactors, where corrosion resistance is a key factor in reliability and safety.

Obtaining new data on beryllium corrosion at critical and supercritical steam parameters contributes to the development of more stable materials for the nuclear power industry of the future.

Purpose

investigation of corrosion processes of binary intermetallic compounds based on beryllium (beryllides) when exposed to high temperatures and water vapor pressure

Expected and achieved results

During the first stage of the project, the CorrSiCa (Corrosion SiC) installation was upgraded to create a separate experimental module for conducting corrosion studies at critical and supercritical parameters of water vapor. This module allows to reach temperatures in the reaction chamber above 500 ° C at water vapor pressures of more than 10 MPa. The installation was initially calibrated for inert gases, hydrogen, and various water vapor parameters. The main methodological parameters of the tests and modes of corrosion effects were determined. The scientific novelty of the project is determined by obtaining new experimental data on the corrosion properties of beryllides under the influence of water vapor at critical and supercritical steam parameters.
