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
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

Four million nuclear jobs by 2050: Who will do them?
Industry leaders from around the globe met this month to discuss the talent development that will be necessary for the long-term success of the nuclear industry.
The International Conference on Nuclear Knowledge Management and Human Resources Development, hosted by the International Atomic Energy Agency, was held in Vienna earlier this month. Discussed there was the agency’s forecast for nuclear capacity to more than double—or hopefully triple—by 2050 and the requirement of more than four million professionals to support the industry.

Forced circulation during and after the Three Mile Island Unit 2 accident distributed reactor fuel into the systems and components of the reactor building (RB) and the auxiliary/fuel handling building (AFHB). Most of the fuel remained in the reactor coolant system and the RB, with smaller amounts continuing to the AFHB systems. Efforts began in 1985 to determine the location and amounts of ex-vessel fuel debris. An overview of the fuel characterization measurements in the RB external to the reactor vessel is presented. The fuel characterization was performed using six methods: neutron assay, alpha assay, sampling, visual inspection, gamma spectrometry, and gross gamma radiation measurements. The method used for the best estimate for a particular region depended largely on the environment and often employed a combination of methods. Using these methods, the minimum and maximum amounts offuel were estimated for each ex-vessel location in the RB. Estimates indicate that between 76.2 and 215.1 kg of reactor fuel currently remain in the RB ex-vessel areas.
