ARPA-E announces $40 million to develop transmutation technologies for UNF
The Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E) announced $40 million in funding to develop cutting-edge technologies to enable the transmutation of used nuclear fuel into less-radioactive substances. According to ARPA-E, the new initiative addresses one of the agency’s core goals as outlined by Congress: to provide transformative solutions to improve the management, cleanup, and disposal of radioactive waste and spent nuclear fuel.

Cyclotrons are one of the most important sources of radionuclides used in biomedical applications. The production of important radionuclides used in single-photon emission tomography techniques such as 123I, 67Ga, 201Tl, and 111In has been based for decades on cyclotrons, typically proton machines with an energy up to 30 MeV. The extraordinary growth of positron emission tomography (PET) has led to the development of new models and to the installation of numerous cyclotrons, typically accelerating protons in the energy range 10 to 20 MeV. These have been used for the production of the main PET radionuclides, namely, 11C, 13N, 15O, and above all, 18F. Recently, their use has been extended to the production of radiometals, like 68Ga, and even to the direct production of 99mTc. Moreover, cyclotrons are a valuable tool for research and for the education of new scientists. This critical review presents the main manufacturers and briefly discusses the characteristics of the models they currently offer on the market.
