MOLYBDENUM ISOTOPE PRODUCTION TARGET Russian patent published in 2001 - IPC

FIELD: nuclear engineering. SUBSTANCE: target used for producing ⁹⁹Mo isotope as uranium fission product providing for reduced loss of fast-decay ⁹⁹Mo and reduced emission of chemical compounds of J fragments into the atmosphere has its core placed in shell with end parts and is made of dispersion compound of U₂Zn₁₇+Zn with uranium content lower than 29.6%. Auxiliary inserts and intermediate layers of metals of group Zn, Pb, Sn, Bi or alloys based on them, or metals of group Cu, Ag or alloys on their base may be placed between core, shell, and end parts. Layer thickness is not to exceed 4% of core sectional area. EFFECT: reduced mass of radioactive wastes and uranium loss, reduced target processing time. 4 cl, 4 dwg
