Division Spotlight
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

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.

The impact of the edge-localized modes (ELMs) on the tungsten divertor erosion by taking into account the screening effect of vapor shielding is analyzed for DEMO steady-state operation condition. The evaluation of tungsten ablation, energy radiation, and absorption by divertor plate due to a single ELM impact is calculated by using a model of vapor shielding inserted in the MEMOS code. The effect of repetitive ELM impact and the tungsten melt layer formation is described by using the model of W monoblock with a compliance layer of Cu alloy between the W and EUROFER water cooling tube.
It is shown that the vapor plasma shielding results in saturation of the single ELM energy accumulated by the divertor plate and that the saturation level depends on the ELM duration. The ablation thickness can reach about 0.01 µm. The total number of ablated particles is rather critical for the shielding formation, and the lifetime of the divertor plate depends strongly on this effect.
