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.

NWMO to select Canadian repository site this year
Canada’s Nuclear Waste Management Organization, a not-for-profit organization responsible for the long-term management of the country’s intermediate- and high-level radioactive waste, is set to select a site for a deep geologic repository by the end of the year.

Carbon Sheet Pump(CSP) has been proposed to be installed on the vacuum vessel wall of the Large Helical Device(LHD) in order to reduce the hydrogen recycling and improve the energy confinement.
The CSP of C/C composite with temperature below 200 °C can pump high energy hydrogen particles such as charge exchange fast neutrals by trapping them. The saturated hydrogen particles can be removed simply by heating the carbon sheet above 800 °C. One of the requirement on the CSP design for LHD is that the temperature of the vacuum vessel must be maintained to be below 70 °C to avoid excessive heat flux to the LHD superconducting magnet system.
The first design of CSP for LHD is presented, and a successful demonstration of heating the CSP carried out.
