Pebble Bed Modular Reactor (Pty) Limited
Senior Design Engineer

   Oct 2002
— Jun 2010

In 2002 I was offered a contract at the Pebble Bed Modular Reactor Company (PBMR) as a specialist finite element analyst in the Structural Analysis Group. I was tasked with all the structural analysis work of the fuel design group. As a result I was involved in the PBMR fuel design software development process.

It was envisaged that the Fuel design software suite would, once fully developed, verified and validated allow PBMR to collate all measured fuel performance data, optimize fuel manufacturing parameters and deliver accurate predictions of current and new fuel configurations’ behavior under irradiated conditions from pre-irradiated characteristics.

My responsibilities:
I was responsible for model- and code generation for all components forming PBMR fuel. This entails creating “smart” parametrized geometry and meshing input decks, building user coding into commercial of the shelf software packages to describe material behavior under neutron irradiation, and managing the flow of data between different fuel component models to ensure correct transfer of loading data and material responses.

I was responsible for the interfaces between the software models I develop and real-life material data and behavior obtained from external contracts describing material behavior of our fuel from atomic lattice level by means of SEM, TEM and atomistic calculation software such as VASP, Gaussian and Crystal.

Further responsibilities, partially in support to the above, included the following:

1. Finite Element Analysis of the PBMR fuel design
I performed all the Finite Element Analyses on the PBMR fuel design as well as design work on certain aspects of the fuel itself. This has resulted in international patents for fuel designs for PBMR with me listed as co-inventor.
2. Design optimization of the Safari reactor fuel sphere test rig
In order to test the survival rate of PBMR fuel spheres under irradiated conditions.
3. Finite Element Analysis of Magnetic Scrubber design
I am listed as co-inventor on the PBMR magnetic isotope scrubber. (MIS) The MIS is passive hardware situated in the reactor outlet duct that uses magnetic fields to force any radioactive isotopes present in the Coolant stream to impinge on a special deposition layer that effectively captures the isotopes for the duration of the plant’s life. The MIS prevents plate-out of, amongst others, radioactive Silver and Cesium on the turbine blades thereby allowing safe (In terms of irradiation dosage delivered to personnel) maintenance procedures on the turbines.
I performed all the Finite Element Analyses on the magnetic scrubber design.
4. General support functions for the PBMR Structural Analysis Group
At structural analysis group I created and maintained an internal database for automated material property inputs for the MSC.Patran software. This was implemented by means of the Patran Command Language. I was also tasked with managing change control of the database data.
