Up until recently, Canada produced approximately half the world’s supply of molybdenum-99, and the US imported approximately 50% to 80% of its supply from Canada. In 2008, there were no facilities in the US manufacturing molybdenum-99. Global efforts to reduce the proliferation of nuclear weapons and deter terrorism are believed, in part, to account for the lack of medical isotope production fa...

Abstract Molybdenum-99 ( 99 Mo) is a parent radioisotope of Technetium-99m 99m Tc) widely used in nuclear diagnostics. The production this by PT. INUKI generated radioactive fission waste (RFW) that theoretically contains 239 Pu and 235 U, posing proliferation risk. This paper discusses the determination radionuclides inventory RFW proposed strategy for its management. was calculated using ORIG...

Monoaryloxide-pyrrolide (MAP) olefin metathesis catalysts of molybdenum that contain a chiral bitetralin-based aryloxide ligand are efficient for ethenolysis of methyl oleate, cyclooctene, and cyclopentene. Ethenolysis of 5000 equiv of methyl oleate produced 1-decene (1D) and methyl-9-decenoate (M9D) with a selectivity of >99%, yields up to 95%, and a TON (turnover number) of 4750 in 15 h. Tung...

Molybdenum-99 is one of the most important radionuclides for medical diagnostics. In 2015, the International Atomic Energy Agency organized a round-robin exercise where the participants measured and calculated specific saturation activities achievable for the 98Mo(n,γ)99Mo reaction. This reaction is of interest as a means to locally, and on a small scale, produce 99Mo from natural molybdenum. T...
