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.

NRC updating GEIS rule for new nuclear technology
The Nuclear Regulatory Agency is issuing a proposed generic environmental impact statement (GEIS) for use in reviewing applications for new nuclear reactors.
In an April 17 memo, NRC secretary Carrie Safford wrote that the commission approved NRC staff’s recommendation to publish in the Federal Register a proposed rule amending 10 CFR Part 51, “Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions.”

This paper presents the final design and main manufacturing aspects of the RFX Magnetizing Winding, now being manufactured by ABB. The winding is designed to store 15 Wb flux and consists of 200 copper turns wound into 40 coils. These are impregnated in groups to form 17 blocks, to satisfy mechanical requirements. The largest coils, with diameters exceeding 8 m, are demountable into two halves, for ease of transport and assembly. The peak turn current is 50 kA and the peak voltage per turn is 700 V. A special connection between the coils allows the resulting voltage across the terminals of each sector to be kept below 35 kV and the voltage to earth below 17.5 kV. To limit diffusion phenomena inside the solid conductors, the innermost 24 coils are wound with two conductors connected in parallel at the coil terminals, transposed with each other at the half coil. Polymide and glass tapes impregnated with epoxy resin provide good insulation without excessive thickness.
