Selecting radiation-shielding lining materials is a critical aspect of nuclear power project construction; it directly impacts safety and engineering quality within the facility and is a key consideration for chief engineers. Among the various shielding materials available, lead-boron polyethylene boards have emerged as a preferred choice for nuclear power projects due to their exceptional protective capabilities.

Compared to traditional shielding materials, lead-boron polyethylene boards offer distinct advantages by providing dual shielding against both neutrons and gamma rays. The boron content within the board efficiently absorbs neutrons, while the integrated lead layer blocks gamma rays. This combination ensures stable, reliable shielding performance that meets the safety requirements of high-radiation areas—such as spent fuel storage zones and equipment rooms—effectively overcoming the limitations of single-material shielding solutions.

Flexibility and adaptability are key highlights of lead-boron polyethylene boards. To accommodate the varying radiation levels and construction environments of different nuclear projects, the boron content and overall thickness of the boards can be customized. This allows them to meet specific construction standards for shielding linings and makes them suitable for a wide range of scenarios, including new construction, facility upgrades, and maintenance.

Furthermore, lead-boron polyethylene boards eliminate the drawbacks associated with traditional lead sheets, such as excessive weight and contamination risks. These boards are lightweight, radiation-resistant, and easy to cut and install, which significantly simplifies construction and boosts efficiency. Their combination of safety, stability, and high customizability makes them a top choice for chief engineers, helping to establish a robust safety barrier for radiation protection in nuclear power projects.
