Abstract

Dry ice blasting, a decontamination method with no secondary waste, is widely used in industry. Its safety is crucial in nuclear power plants. In this study, we carried out dry ice blasting treatment on five materials commonly used in nuclear power plants, and successively carried out mass damage research, surface erosion morphology research and mechanical property research. The results show that dry ice blasting is safe for 304 and 316 stainless steel, and brass, but not for aluminum and PVC. The maximum peeling mass for stainless steel and brass was found to be 6.15 g/m² and 15.38 g/m², respectively, both within China's energy industry standard (NB/T20142-2012). The process increases surface roughness but doesn't affect the material's microstructure. We recommend lower air pressure and a smaller impact angle for operational equipment to minimize damage, and higher pressures and larger angles for decommissioned equipment to enhance the decontamination effect.

干冰爆破技术安全性能的试验研究

干冰爆破作为一种不产生二次废物的净化方法，在工业上得到了广泛的应用。它的安全性对核电站至关重要。在本研究中，我们对核电站常用的5种材料进行了干冰爆破处理，并先后进行了质量损伤研究、表面侵蚀形貌研究和力学性能研究。结果表明，干冰爆破对304、316不锈钢和黄铜是安全的，但对铝和PVC则不安全。不锈钢和黄铜的最大剥离质量分别为6.15 g/m2和15.38 g/m2，均符合中国能源行业标准（NB/T20142-2012）。该工艺增加了表面粗糙度，但不影响材料的微观结构。我们建议降低运行设备的空气压力和较小的冲击角，以尽量减少损坏，而退役设备的压力和较大的角度，以增强去污效果。
