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.
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.

Pact signed on potential BWRX-300 deployment in Saskatchewan
Ontario-based GEH SMR Technologies Canada Ltd. and the Saskatchewan Industrial and Mining Suppliers Association (SIMSA) announced yesterday the signing of a memorandum of understanding focused on the potential deployment of the BWRX-300 small modular reactor in Saskatchewan.
The MOU calls for engaging with local suppliers to maximize the role of the Saskatchewan supply chain in the nuclear energy industry.

Silicon carbide (SiC) fiber–reinforced SiC matrix (SiCf/SiC) composites, employing two SiC fibers, KD-I and KD-II, respectively, were fabricated by the precursor infiltration and pyrolysis process. A pyrocarbon coating was used as the fiber-matrix interface. In addition, the effects of heat treatment on the properties of the SiC fibers and SiCf/SiC composites were investigated. Results revealed marginal performance degradation of the KD-I and KD-II SiC fibers after heat treatment at 1100°C for 1 h. However, heat treatment at 1400°C for 1 h led to the decrease in the single-filament tensile strength of the KD-I and KD-II SiC fibers by 50.2% and 10.1%, respectively. In addition, the flexural strength of the SiCf/SiC composites, which were fabricated using the KD-I and KD-II SiC fibers, decreased by 49.6% and 15.9%, respectively. The difference in the composition of the KD-I and KD-II SiC fibers demonstrated that the SiC fibers and SiCf/SiC composites decreased by varying degrees.
