Empowering advanced nuclear materials research! The Chongguang cryogenic cold trap optimizes the high-temperature irradiation environment of Peking University’s three-beam irradiation facility.

In the development of advanced nuclear reactors, research on the irradiation performance of structural materials is a critical step in overcoming technical bottlenecks. The degradation of material properties caused by transmutation products such as hydrogen and helium, along with the interference of carbide formation under high‑temperature irradiation conditions on experimental accuracy, has long posed core challenges for researchers. To simulate the real‑world operating environment of nuclear reactors and conduct precise irradiation experiments on nuclear materials, Peking University has established a three‑beam irradiation facility dedicated to advanced nuclear materials research. Centered around a 1.7 MV tandem accelerator, this system integrates multiple key pieces of equipment to form a controllable irradiation research platform. As a core component supplier for this cutting‑edge research apparatus, Zhongguang leveraged its technological expertise in low‑temperature control and impurity suppression to custom‑integrate a cryogenic cold trap into the irradiation chamber. This solution effectively addressed the challenge of carbide formation under high‑temperature irradiation, providing essential support for stable system operation and reliable experimental data, thereby helping China take a solid step forward in the field of advanced nuclear materials research.
