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.”

The China Fusion Engineering Test Reactor (CFETR) is a new superconducting magnet tokamak. The vacuum vessel (VV) is one of the core components of the CFETR device, and it will provide a high-vacuum environment for the plasma, improve radiation shielding and plasma stability, and provide support for in-vessel components. The 1/8 VV sector mock-up has been designed and manufactured in the Chinese Academy of Sciences, Institute of Plasma Physics (ASIPP) from a few years ago to verify the design and key technologies to be used in the future. The production and assembly of the 1/8 VV sector are not in the same place, so lifting lugs and a support platform were designed for lifting and supporting the 1/8 VV sector mock-up. The detailed design of the 1/8 VV sector mock-up lifting lugs and support platform are described. There are two design options for the lifting lugs—removable and nonremovable—and there are also two design options—the integral and the separated—for the supporting platform. At the same time finite element analysis and assessment of the lifting lugs and supporting platform were done. The maximum stress does not exceed the allowable stress of the material, in consequence both of the two design options are practicable, respectively. All the design and analysis results will provide technical support for the assembly of the 1/8 VV sector in the future.
