AP14871210 Study of the influence of hydrogenation and helium embrittlement processes in materials for dispersed nuclear fuel of HTGR type reactors

Goal of the work:

The goal of this project is to study the influence of hydrogenation and helium embrittlement processes in materials used for dispersed nuclear fuel in HTGR type reactors. The main objective of the project is to understand the mechanisms, characteristics and consequences of these processes on the structure and properties of materials used in nuclear technology.

Relevance of the project:

The relevance of the project to study the influence of hydrogenation and helium embrittlement processes in materials for dispersed nuclear fuel of HTGR type reactors is emphasized by the following aspects: Hydrogenation and helium embrittlement are potential threats to the safety of operation of nuclear reactors. The study of these processes is necessary to prevent possible emergency situations and ensure stable and safe operation of reactors. Understanding the mechanisms and factors influencing hydrogenation and helium embrittlement will make it possible to develop methods and technologies to increase the service life of HTGR nuclear reactors. This is important given the increasing average age of existing nuclear installations around the world. The problems of hydrogenation and helium embrittlement are relevant for many countries with nuclear technology. The study of these processes and the development of methods for their management are the subject of international cooperation and exchange of scientific knowledge and experience. In this regard, the study of the influence of hydrogenation and helium embrittlement processes in materials for dispersed nuclear fuel of HTGR type reactors is a relevant and important area of scientific research.
