John Billingsley
John Billingsley
Consultant

John is a shielding consultant for Cerberus Nuclear. Prior to working for Cerberus, he was a nuclear analyst for UKAEA where for the past 2 years he was involved in the STEP programme using Open MC neutronics simulations to analyse tritium breeding ratios. During this time, he has gained experience with CSG- and CAD-based neutronics calculations, and methods of automated data analysis using Python scripting. Alongside his neutronics experience, John has extensively contributed to software development and to the open-source Monte Carlo code OpenMC. He also has experience in delivering training on neutronics PhD students at the University of York as part of the EPSRC Fusion CDT programme.

Henry Faulkner
Consultant

Henry joined Cerberus following his Summer Placement with the company for his NTEC Masters Dissertation. Henry has gained extensive experience using MCNP to model fissile arrays of barrels containing separated plutonium waste with differing compositions during his summer project. He analysed results using machine learning methods in Python to predict the safest possible arrangement of units. Henry is looking to build upon his knowledge and academic experience in both the shielding and criticality safety teams. In addition to his consultancy work, he is attending shielding and criticality mentoring sessions lead by our experienced team members in line with industry standards.

Consultant

Jacob completed his summer placement at Cerberus Nuclear for his NTEC Masters dissertation and has since started full time with the company.

Jacob’s summer project included criticality calculations on three distinct fissile systems including a random and uniform heterogeneous system with immiscible liquids. He developed software using Python to generate all MCNP input files. This allowed for quick changes to be made and a range of properties investigated such as enrichment, particulate size and material, volume fraction and moderator material. Jacob is also attending shielding mentoring sessions lead by experienced members of the shielding team in order to further his career as a shielding consultant.
