Optimal solution for radiation protection foaming of potassium neodecanoate sealing material

In the daily operation of nuclear power plants, the selection and optimization of sealing materials are a crucial link. Seal materials not only need to have excellent mechanical properties and corrosion resistance, but also need to be able to withstand the influence of nuclear radiation and ensure the safe and stable operation of nuclear power plants. Potassium neodecanoate (CAS 26761-42-2) has shown great potential in this field as an emerging radiation protection material. This article will start from the basic characteristics of potassium neodecanoate, combine relevant domestic and foreign research literature to deeply explore its application in nuclear power plant sealing materials, and propose a comprehensive radiation protection foam optimization solution.

This solution aims to enhance the radiation absorption and thermal insulation properties of potassium neodecanoate materials by introducing foaming technology. Specifically, by forming tiny bubbles inside the material, not only can the specific surface area of the material be increased, the radiation absorption efficiency can be improved, but the density of the material can also be reduced and the overall weight can be reduced.

Domestic research progress

In recent years, domestic scientific research institutions have gradually increased their research on potassium neodecanoate. For example, a study by the Institute of Nuclear Energy and New Energy Technology of Tsinghua University showed that the service life of potassium neodecanoate foamed materials can be extended to more than ten years in a simulated nuclear power plant environment.

International Research Trends

Internationally, the Oak Ridge National Laboratory is conducting a study on the long-term stability of potassium neodecanoate in extreme radiation environments. Preliminary results show that the material can maintain good performance under continuous high dose radiation.
