【 摘 要 】

To enhance the safety of the transport of dangerous goods in tanks, the latter should improve the mechanical (physical) protection to prevent accidental damage to the boilers, such as objects containing dangerous goods directly. Damage to the boiler will almost inevitably leads to such consequences as decompression, the leakage of liquid radioactive waste and radiation pollution of the surrounding area. This article discusses scenarios accidents when overloading with marine railway transport; the explosion of gas cylinders on board the vessel. Calculation formulas are obtained to determine the speed at which the shards is provided by probabilistic the breakout a certain thickness of the tank walls. Received probability distribution function for the specified parameters shards and material barriers, which was determined by conducting a full-scale experiment. The results of theoretical studies, experiments used to improve designs of tanks carrying LRW and recommendations for improving the security of multimodal transport.
