Description

The International Atomic Energy Agency has recently initiated a project on open source nuclear codes for reactor analysis (ONCORE). The IAEA aims to support and strengthen its Member States’ capabilities in the field of advanced reactors modelling and simulations, and is making use of ONCORE platform to support, coordinate, and collaborate in the development of open-source code for research and development and education and training purposes. Modelling and simulation of nuclear reactors with their complex geometry, and involvement of different physics and scales is one of the major challenges in the field. Development of new reactor designs also requires understanding of new and better approach to model them appropriately. The IAEA’s ONCORE initiative is an effort to bring together developers from across the world to contribute and collaborate in the development of codes, which are open source and can further be developed as per the requirements of the reactor design. Multiphysics code take an integrated approach to model different physics at different scales, and therefore has its own challenges to address. This webinar aims to provide some insights into Multiphysics modelling of advanced nuclear reactors, their benefits, challenges and different approaches to develop these complex nuclear codes. This webinar is also part of the outreach effort to engage interested member states in the ONCORE initiative. The webinar is particularly useful for professionals and researchers in this field.

Purpose

The purpose of the webinar is to discuss and present the state-of-the-art as well possible challenges in the area of Multiphysics modelling of advance nuclear reactors.

Objectives

The main objectives of the event are to:

• Understand the state-of-the-art in Multiphysics modelling to optimize design and safety of advanced nuclear reactors;
• To provide information to member states on how to get involved in the IAEA's project on open source platform for reactor analysis;
• Understand the Challenges in multiphysics modelling of advanced reactors;
• Understand the current R&D needs.

Topics

• Multiphysics modelling: from segregated to integrated coupling strategies
• Multi-physics modelling and simulation using open-source software
• Multiphysics Coupling in the MOOSE Framework
