Engineer – Core Design and Performance

We are Rolls‑Royce SMR, a pioneering leader in small modular reactors. The Core Design team ensures the SMR reactor core operates within safety limits while delivering optimal performance and economic efficiency.

About the role

As an Engineer – Core Design and Performance you will develop, analyze, and assess SMR reactor core performance. You will support and enhance neutronic and thermal‑hydraulic models, contribute to safety justification and performance optimisation, and develop core analysis methods and tools.

Responsibilities

• Support development and refinement of neutronic and/or thermal‑hydraulic core models.
• Deliver technical analysis across core physics, kinetics and thermal‑hydraulics disciplines.
• Contribute to assessment of steady‑state and transient core performance.
• Support evaluation of core‑related fault sequences and plant behaviour.
• Assist in developme...
