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
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

Zaporizhzhia ‘extremely fragile’ relying on single off-site power line, IAEA warns
Europe’s largest nuclear power plant has just one remaining power line for essential nuclear safety and security functions, compared with its original 10 functional lines before the military conflict with Russia, warned Rafael Mariano Grossi, director general of the International Atomic Energy Agency.

Recent Experiments at the TSTA have demonstrated successful operation of the integrated exhaust gas processing loop. In these experiments the final subsystem, the cryogenic compound pumps, was integrated into the loop. These tests were conducted with a tritium inventory of about 110 g and a processing rate of about 1 kg per day—full scale for a fusion machine such as ITER. The tests demonstrated a workable-exhaust gas processing system which could be used for ITER. Other recent tests include testing on a single shot tritium pellet injector developed and fabricated at ORNL.
