Author analysis reports which summarise key results for system performance including pressure drop, NPSHa, control philosophy, cavitation margin, thermal performance
Use analysis for sizing key components to achieve system requirements (i.e., pumps, valves, tanks, HX etc.)
Build and analyse 1D representations of fluid systems, including system architecture, pipework, components and control philosophy (mostly liquid, but some gaseous systems)
Apply knowledge of thermo-fluid behaviour and system design principles to propose design/control modifications to meet system performance/safety requirements
Scoping of analysis requirements to demonstrate a system meets its performance and safety requirements
In some scenarios, a higher fidelity 2D/3D analysis approach may be required and there may be opportunities to support the delivery of Computational Fluid Dynamic (CFD) analysis within the group

Company
Overview
A team of 15 engineers at Rolls‑Royce began designing a compact, scalable nuclear solution in 2016.
Blends decades of naval reactor experience with advanced manufacturing.
Modules are nearly 90% factory‑built across 1,500 parts, then shipped and assembled on site—cutting costs, time and complexity.
The company uses a boron-free primary circuit, eliminating toxic boric acid and reducing water use and waste.
Backed by strategic investors and partners like ČEZ and Siemens Energy to support global rollout.
Positions itself as a repeatable, investable product offering dependable 'always-on' clean energy to grids and industries.
Culture + Values
Innovative and forward-thinking.
Focused on safety, quality, and integrity.
Committed to delivering customer success.
Collaboration and teamwork across functions and regions.
A culture of continuous learning and development.
Driving a performance culture with a focus on results.
Empowering employees to make decisions and take responsibility.
Environment + Sustainability
Focus on reducing carbon emissions through advanced nuclear technology.
Development of compact, small modular reactors (SMRs) to provide cleaner, low-carbon energy.
Sustainability goals to align with international frameworks such as the Paris Agreement.
Supporting the UK government’s energy transition strategy with clean, reliable energy solutions.
Inclusion & Diversity
Striving for greater gender balance in the workforce.
Creating an inclusive and respectful work environment.
Empowering diverse talent to contribute at all levels of the organization.
