Effect of boron-containing polyethylene composites configurations on neutron shielding performance

JIAO Limin and colleagues at the China Institute for Radiation Protection used TopMC to calculate the neutron fluence through polyethylene composites with different configurations, thicknesses and boron contents, and analysed how a gradient structure affects shielding performance, providing a reference for the design and optimisation of shielding materials for spent fuel transport casks. Under the calculation conditions set in the paper, the gradient-configuration composite achieved a neutron shielding enhancement of 9.39% compared with the uniform-configuration composite.

The work was published in Engineering Plastics Application (2025, Vol. 53, No. 7, pp. 69–74), a journal that has won the National Journal Award three consecutive times. Sponsored by the No. 53 Research Institute of China North Industries Group, it has long covered research and applications of engineering plastics and composites. The “Calculation program” section on page 71 of the paper states that TopMC was used for the shielding calculations.
