Safe management of radioactive sources in discussion of categories 3- 5 in Cuba

Radioactive sources in disuse of categories 3-5 that are stored in the management facility of Radioactive waste from Cuba, mostly for more than 20 years, has been collected from different entities of the country, generally of industries, where they were exposed to environmental conditions severe This has resulted in corrosion and deterioration of the devices that contain them. For this reason it is necessary to dismantle these equipment to recover the sources and condition them in stainless steel capsules The capsules with the conditioned radioactive sources are placed in containers with adequate shielding for safe storage in the installation. These operations require authorization from the National Nuclear Safety Center, the authority regulatory, for which the safety record of the practice, which includes detailed operational and safety procedures, proper planning of operations and estimation of operational doses and for members of the public, as well as the evaluation of security. The radiological emergency plan was also elaborated, based on the results of the practice safety assessment. The documentation was evaluated by the CNSN and the Operation license. For the dismantling of some models of nuclear meters was it is necessary to design and build special tools, in order to facilitate the operations of extraction of radioactive sources and optimize doses to operators. They were also designed and they built containers with the necessary shielding for the safe storage of the capsules with the conditioned sources, which allows its recovery for its final management.
