Abstract

The topic of my thesis is the issue of the treatment of aging of pipelines. Based on international literature I have summarized the principles of the treatment of aging of pipelines in my thesis, however primarily in connection with the lifetime extension of Paks Nuclear Power Plant. I demonstrated the damage processes of the pipelines, their reasons and the options to prevent damages. It was a task that how can the corrosion allowance taken into consideration in strength calculations. The Nuclear Power Plant has adapted the US regulation on the same subject during the ongoing lifetime extension process (according to the international practice). The determination of the required wall thickness enhanced with the corrosion allowance and the qualification of the existing pipelines were carried out based on the inspections implemented according to the Hungarian standards based on the ASME regulation system and the strength calculations. I have introduced the economic aspects of the damages and of the preventions, which I have demonstrated also in the reflection of Paks Nuclear Power Plant. To operate the pipelines safely it is extremely important to forecast accurately the effects of the damaging processes to the pipelines on the one hand due to economic reasons and on the other hand due to the harmful effects on human life and on the environment. For the future I find it important to study the technologies of the aging treatment further because of the necessity of the pipeline damage determination and of the more specific lifetime determination. With this I could not only deepen my professional knowledge but am also able to contribute to increase safety in my working environment.
