MANUFACTURE OF 99MO-FORMING TARGET USING LOW-ENRICHMENT URANIUM AND 99MO-FORMING TARGET COMPRISING LOW-ENRICHMENT URANIUM

摘要

PURPOSE: To provide manufacture of a<99> MO generating target using low level enriched uranium and a<99> MO generating target made of low level enriched uranium. CONSTITUTION: A primary target 10 comprises an inner side tube 12, outer side tube 26 and a foil 22 interposing therebetween. The inner side tube 12 comprises an outer side surface, first end portion 14 and second end portion 16. The foil 22 is made of a fissile material and almost covers the outer side surface of the inner side tube 12. The outer side tube 26 comprises an inner side surface, first end portion 14 and second end portion 16. The inner side surface of the outer side tube 26 accommodates the inner side tube 12 almost covered by the foil 22. The inner side tube 12 and outer side tube 26 contacts in a condition of being pressed toward each other and thus good mechanical contacts between the inner side tube and foil 22, and between the outer side tube 26 and foil 22 are secured.
