A TYPE B(U) PACKAGE TO STORE AND TRANSPORT MEDICAL SOURCES

ENEA is designing a new package, called CESM, to store and transport to the final disposal all the radioactive sources collected from many hospitals in the past. The paper shows the storage requirements and all the steps carried out to prepare a safety report to get the package approval from the competent authority with the scale-up criteria and calculation codes used for thermal, mechanical and shielding analyses and the experimental planning for the drop test. The new package is the result of applying again the scale-up factors on the two packages CF6 and C66 certified in the past as Type B. The FEM analysis integrates the mechanical analysis and the 9 m drop test is planned too. ENEA has shown its planning to the Competent Authority and it has got the first comment on the best way to follow to save time in the approval procedure.
