Abstract

Initial development work and trial irradiations were conducted to produce the in-demand medical isotopes ⁶⁴Cu and ⁶⁷Cu via the reactor-based fast neutron ⁶⁴Zn(n,p)⁶⁴Cu and ⁶⁷Zn(n,p)⁶⁷Cu reactions using enriched zinc targets. Boron-nitride shielded sample holders were used to reduce the thermal neutron flux to the zinc targets and diminish the production of undesired ⁶⁵Zn. Irradiated oxide targets were dissolved and preliminary separations achieved copper yields of ~95 % and zinc separations factors greater than 10³ after one ion exchange pass. Further development would allow the production of mCi levels of ⁶⁴Cu and ⁶⁷Cu per irradiation, providing sufficient activity for small mammal research studies.
