<\/div>T<\/span>ritium is a radioactive isotope of hydrogen that plays a key role in the development of nuclear fusion energy, which is considered one of the most promising energy sources due to its ability to generate large amounts of power with a reduced environmental impact. However, because of its radioactive nature, the <\/span>handling of this isotope requires strict safety and control measures, particularly in facilities dedicated to the processing and storage of tritiated gases.<\/b><\/p>\n

Radiation protection regulations impose strict limits on the release of radioactive substances into the environment. Consequently, facilities that handle tritium incorporate dedicated detritiation systems whose primary function is to minimize emissions while ensuring both environmental protection and worker safety<\/span><\/p>\n

The challenge of controlling tritium permeation<\/h5>\n

One of the main challenges associated with tritium is its high <\/span>diffusivity<\/b> through a wide range of metals and industrial structures. This phenomenon, known as permeation, can lead to leaks that are difficult to detect and may compromise both the efficiency and safety of processing systems. Therefore, the development of accurate models capable of predicting tritium behavior and quantifying permeation losses is of great importance.<\/span><\/p>\n

This work focuses on the <\/span>study of tritium permeation in a radioactive gas treatment system and on the evaluation of potential mitigation strategies<\/b>. The main objective is to assess the amount of tritium that diffuses through the walls of pipes and industrial equipment and to propose a solution capable of reducing these losses.<\/span><\/p>\n

To achieve this goal, two different models were developed using EcosimPro, a simulation software widely employed for the design and analysis of steady-state and transient systems. The first model represents the reference system, whereas the second incorporates a 1 \u00b5m-thick alumina (Al<\/span>2<\/span>O<\/span>3<\/span>) internal coating applied to pipes and critical components.<\/span><\/p>\n
