The British intends to develop a new material for sealing and storing projectiles

The number of nuclear accidents at the Fukushima Daiichi nuclear power plant in Japan has been more than four years. Subsequent radiation treatment work still faces many challenges. Imperial College of Technology announced on the 16th that the school’s research team is preparing to develop new materials that can be used to seal shots in order to improve the effectiveness of such clean-up work.

According to the Imperial College, a large number of radioactive wastes are generated every day to cool down an accidental nuclear reactor. Engineers have set up filtration facilities on the site of the Fukushima nuclear accident to treat waste water. High-dose wastewater absorbers are used to filter the radiation, but how to seal these emissions is still a major problem.

A joint project of Imperial College researchers will strive to develop a new type of glass material. When the wastewater absorber completes the filtration and contains radiation, the new glass material will be combined with these wastewater absorbents to form a new one. Solid composition. This material has a high degree of stability and can store the projectiles for a long period of time.

Researchers say that radiation produces a lot of heat during long-term decay, and they need to experiment to verify that the new glass material can withstand this heat. Researchers will establish a numerical model for this purpose to quantify the level of heat generated by radioactive decay to accurately assess the effects of radiation treatment with new materials.

If the new material is proven to be effective, it can be used directly to seal high-dose wastewater absorbents that filter the radiation without the need for more complex and time-consuming processes to perform the storage.

The researchers said that the key to the success of the follow-up cleanup work at the Fukushima nuclear accident is how effective the radiation treatment is. Once this study is successful, it will help resolve such problems and can be used to dispose of nuclear waste from British nuclear power plants. (Reporter Zhang Jiawei)
