Reactor Physics

Why this role is different
Real scope, real ownership. A (team size) engineering team, not a 400-person division. Your core design decisions reach the CTO the same week you make them.
Licensing-grade work. Your analyses become part of a formal NRC submittal – the highest-rigour environment in the industry, and a credential that follows you for the rest of your career.
Two missions in one machine. Carbon-free power and isotope production for cancer diagnostics and treatment.
What you'll own
You’ll be the reactor physics authority on the MMR core – from first-principles modelling through to defending your numbers in front of a regulator.
Core design & optimisation – define and iterate the core configuration, working the trade space between reactivity, thermal limits, cycle length and manufacturability.
Neutronics analysis – criticality and reactivity coefficients, burnup and depletion, cross-section generation, flux and power distributions.
Shielding & dose – shielding design, dose rate calculations, and validation of radiation barriers.
Fuel cycle – fuel management strategy and fuel cycle analysis for a first-of-a-kind core.
Licensing support – produce the analyses and technical documentation that support the NRC submittal, and engage directly with regulators and reviewers.
Safety analysis – support risk assessment and failure mode analysis on reactor components alongside the safety team.
Method & tool development – improve the models, workflows and verification practices the team will rely on for the next decade.
Essential
MSc in Nuclear Engineering, Reactor Physics, or a closely related field.
Strong grounding in reactor physics – you can explain why a core behaves the way your model says it does.
Hands-on experience with at least one Monte Carlo or deterministic neutronics code: Serpent, MCNP, SCALE, PARCS , or equivalent.
Working knowledge of nuclear safety principles and a regulatory framework ( NRC, IAEA, or a national equivalent ).
