Application of Shandong Xinxing Borated HDPE Sheets in the Field of Nuclear Fusion
I. Application Background and Core Value
As a new generation of high-efficiency neutron shielding material, borated HDPE sheets play an irreplaceable role in safety protection during nuclear fusion experiments. Its core working principle relies on the high neutron absorption cross-section of boron‑10 isotopes and the neutron moderation property of hydrogen atoms in polyethylene, forming a dual protection mechanism of moderation and absorption. It effectively shields high-energy neutron radiation generated by nuclear fusion, ensuring stable operation of experimental devices and the safety of researchers.
II. Material Shielding Mechanism and Technical Characteristics
Borated HDPE sheets are vital for nuclear fusion experiments and serve as advanced high-performance neutron shielding materials that deliver critical safety protection for experimental equipment and scientific staff. The material takes advantage of the strong neutron capture capability of boron elements (especially boron‑10 isotopes), which works synergistically with the moderation performance of the polyethylene matrix to establish a dual protection mechanism: moderation first, followed by absorption.
- High Shielding Efficiency: Depending on sheet thickness and boron loading, the neutron shielding rate of borated HDPE sheets can reach up to 98.7%.
- Customizable specifications: thickness ranging from 10 mm to 380 mm, boron content adjustable from 1% to 40% to match different shielding zones.
- Lightweight and High Mechanical Strength: Its density is far lower than traditional shielding materials such as lead, facilitating transportation, installation and structural design. Meanwhile, the material possesses good mechanical strength and impact resistance.
- Radiation and Corrosion Resistance: Capable of long-term stable service under intense radiation and complex chemical environments with excellent anti-ageing and anti-corrosion performance.
- Flexible Machinability: Products can be fabricated into components of various shapes and dimensions by adjusting boron concentration and thickness according to the requirements of experimental devices. We can produce design drawings based on application requirements and develop detailed assembly schemes.
