IAEA Interregional Workshop on Aspects of Modelling and Simulation in Gen-IV Type SMR Developments

3 Nov 2025, 08:30 → 7 Nov 2025, 14:00 Europe/Moscow

Hosted by
The Government of the Russian Federation
through Rosatom Technical Academy
Moscow, Russian Federation
3 to 7 November 2025

Purpose

The purpose of the event is to train participants on the novel approaches in physical models and simulation tools for innovative Small Modular Reactors (SMRs), within the framework of the six reactor concepts outlined by the Generation IV International Forum (GIF).

Scope and Nature 

This training course will include a combination of classroom lectures, discussions, and interactive exercises. It will be conducted as a series of presentations by IAEA staff,  international and local experts. The programme will also include discussions, case studies, peer-to-peer exchange of good practices, and working sessions on related topical issues
