ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

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.
