Research status of ductile iron nuclear spent fuel container in Germany

Siempelkamp company of Germany began to develop 100 ton ductile iron nuclear spent fuel container in 1987. During the development of the container, the company found that the hardness of sand sample greater than 3Mpa is helpful to realize the riser free casting of 100 ton ductile iron nuclear spent fuel container. In order to realize no riser casting and reduce the cost, the company adopted furan resin and phosphoric acid to achieve this goal after many attempts; in order to reduce the solidification time, the company independently developed a patented cooling system. Finally, the company used furan resin as binder for sand box casting, and successfully poured 100 ton ductile iron nuclear spent fuel container with self-developed cooling system. The performance of nuclear spent fuel container produced by simbei company in Germany was the same.

Simbei company has developed two series of 100 ton ductile iron nuclear spent fuel containers, castor and tn1300, with a weight of 160t. They are used for dry storage of nuclear spent fuel or for storage and transportation. More than 1100 sets have been produced. The 100 ton nuclear spent fuel containers produced by simbei company are shown in the figure.
