Feasibility Research of ⁹⁹Mo,³¹I and ⁸⁹Sr Production by Medical Isotope Production Reactor

The recovery of ⁹⁹Mo and ¹³¹I was studied from simulation of Medical Isotope Production Reactor（MIPR） loop liquid delivery system,and the ¹³¹I recovery and ⁸⁹Sr purification from simulation of MIPR gaseous loop.The results indicated that the overall recovery yield of ⁹⁹Mo and ¹³¹I from simulation liquid delivery system were 56.4% and 50.2% respectively,while the contents of impurities meet Pharmacopoeia require.¹³¹I in gaseous loop can be recovered with absorbent,and the recovery yield is more than 90%.The ⁸⁹Sr recovered from by-pass gaseous loop can be purified by chemical separation,and the over all recovery yield of strontium is more than 70%,while the contents of impurities meet Pharmacopoeia re-quire.The results showed that MIPR can be used for ⁹⁹Mo,¹³¹I and ⁸⁹Sr production.
