Rolls-Royce SMR taps ŠKODA JS for reactor safety hardware
A Rolls-Royce small modular reactor program has signed an agreement with the Czech firm ŠKODA JS to design and manufacture Control Rod Drive Mechanisms, which control reactor output and enable rapid shutdowns in emergencies. The move is described as a step toward enabling serial production and safety-focused manufacturing for 470 MW class reactors.
What changed
Rolls-Royce SMR announced a supply agreement with ŠKODA JS to deliver critical Control Rod Drive Mechanisms (CRDMs) for its 470 MW small modular reactor design. The CRDMs are safety devices that adjust the reactor’s power during normal operation and insert control rods quickly to shut the reactor down in an emergency. The Czech company will first build a prototype and then prepare its facilities for mass production, signaling progress toward commercial manufacture of these safety components within Europe.
Key facts at a glance
- CRDMs are essential for regulating reactor output and safe shutdown.
- ŠKODA JS will design and manufacture these devices for Rolls-Royce SMR.
- The plan includes creating a prototype first, then scaling to serial production.
- Rolls-Royce expects the collaboration to open long-term revenue opportunities tied to each new power station built.
Who is affected
The deal involves Rolls-Royce SMR as the buyer and ŠKODA JS as the supplier in the European nuclear manufacturing supply chain. Impacts are primarily on the companies’ workforces and their engineering contracts, with broader implications for how quickly Rolls-Royce can move toward serial production of its 470 MW modular reactors.
Practical next steps
- ŠKODA JS to complete a dedicated prototype for the Rolls-Royce design.
- Facilities to be upgraded or prepared for serial manufacturing in Europe.
- Rolls-Royce SMR to assess additional supplier and manufacturing needs as the program progresses toward commercial units.
- Stakeholders should monitor regulatory updates that affect licensing, construction timelines, and public safety standards for modular reactors.
Limits and questions
Details on project timelines, total expected orders, and specific contracting terms were not disclosed. The article notes that very few European manufacturers hold the required qualifications for such components. It does not specify which other suppliers are involved or the exact safety certifications required for CRDMs in Rolls-Royce’s program.
