Fission ~(99)Mo Production technology

摘要

This paper describes a production technology of fission ~(99)Mo in the Department Isotope, CIAE. The irradiation target is tubular U-Al alloy containing highly enriched uranium. The target is irradiated in the swimming pool reactor core. The neutron flux is about 4 X 10~(13)/cm~2.see. The production scale is 3.7-7.4 TBq (100-200Ci) of fission ~(99)Mo per batch. Total recovery of ~(99)Mo is more than 70%. The production practice proves that the process and equipment are safe and reliable.
