Simon Connell - Modeling Pebble Bed Type High Temperature Gas Cooled Reactors Using Particle Transport Code


Description:

The accurate modeling of nuclear reactors is essential for design, regulation, safety analysis, operations and forensic analysis. In the most demanding case, the calculations must be sufficiently rapid that they are much faster than natural time for burn and decay processes while still being sufficiently accurate. There are two classes of approaches to modeling the neutronics of nuclear reactors. The first is deterministic, where the neutron transport equations are solved using a combination of approximations and numerical methods based on a space-time discretization. Usually, compromises are made in the accuracy of the model in terms of the level of approximations used, the scale of the discretization and the level of geometric and material detail, in order to achieve a sufficiently fast speed of calculation. The error induced due to the compromises made is offset with compensating modifications of the physical description or processes. The second class of models is stochastic in nature. Here many statistically independent histories for each neutron event and all secondary events related to its interactions are tracked and various physical data is stored for later statistical analysis. The physics content manifests through the microscopic cross sections (probabilities) for each interaction. The thermal and material information is encoded into thermally averaged macroscopic cross sections, which are assembled together with the microscopic cross sections. The geometrical information is reconstructed using technical drawings of the system, essentially to the desired precision.  The full physics of the reactor are in this way encoded into probability distributions to be sampled on an event-by-event basis in the particle tracking and data extraction process, as various objects tracked are manifested in different regions of the reactor. The particle transport code, Geant4, developed for high energy physics, has recently been extended to accommodate lower energy nuclear physics and energy scales down to the far sub-eV region. In this work, the application of the Geant4 framework to a new acalculations.

Presenter:

Simon Connell is professor of physics at the University of Johannesburg within the Faculty of Engineering and the Built Environment in the Department of Mechanical Engineering Science.  He has research interests in Particle Physics, Nuclear Physics, Nuclear Energy, Materials Science, Quantum Physics, High Performance Computing and Applied (innovation) Physics. His research spans the fields above as does his teaching. He has participated in developing a 10 Module accredited course at the 4th year level in Nuclear Energy. He has published over 150 papers in International Journals and is an ATLAS author. His rating by the SA Research Funding Agency (NRF) cites him as having “considerable international recognition”. He is a past president of the South African Institute of Physics. 

He is the founding member of the South African participation in High Energy Physics at the ATLAS Experiment at CERN, where with his group he participates in a Beyond Standard Model searches as well as engineering and technical activities. Specifically, they are part of a team that searches for the force carrier particles associated with dark matter, known as the dark vector boson(s). They use the discovered Higgs as a portal, but they extend the search to include also possible undiscovered Higgs’s as further portals. Their current publications have shown two dark vector boson candidates. The work focuses on finding further candidates leading to discovery or finding a background process, which would otherwise explain these events. The group is also working on Radiation Hard Humidity Sensors for the upgraded Inner tracker, and here there is a collaboration with colleagues in the Department who are experts in Optical Fibre based sensors. A further contribution to ATLAS is research on containerization and virtualisation of High-Performance Computing based on clusters as a new solution for the main trigger and data acquisition (TDAQ) farm. He has also worked for many years at the European Synchrotron Research Facility (ESRF). The current research focus is to develop a gamma ray laser based on aligned charged particle beam incidence on a specially fabricated diamond superlattice functioning as a crystalline undulator. This is done as part of the PEARL EU collaboration. He is interested in technology for competitive industry and in i

James Larkin - An Introduction to Nuclear Security and Why its Important to You

Description:

The nuclear fraternity is a small world, and we are all affected by what one another does. A nuclear security incident in one part of the world can and will have a profound effect on the rest of the nuclear arena. We all need to become and remain aware that there are people in the world today who wish to use nuclear and radiological material for malevolent uses, and we all need to do our part in securing nuclear and radiological material, and the associated information from falling into the wrong hands.

John Roberts - Status of Nuclear Energy Worldwide


Description:

Many countries around the world are now building a new, modern, fleet of nuclear power plants with many more either planning or considering nuclear to provide safe, reliable electricity and also to help reduce their carbon emissions. Many countries also have a legacy fleet of reactors that require decommissioning while some are also developing geological disposal facilities. This presentation will provide an overview of the current status of worldwide nuclear projects and reflect on some of the issues and challenges that have slowed down the wider acceptance of nuclear energy. If nuclear is chosen by some countries for their electricity why is it not chosen by all countries? The recorded presentation can be found here. The powerpoint presentation can be found below.
