Škoda JS to supply control rod drives for Rolls-Royce SMR's reactors

Rolls-Royce SMR has appointed Czech company Škoda JS as the exclusive supplier of control rod drive mechanisms for its small modular reactor design. Control rod drives are critical safety and operational components that manage the chain reaction inside the core. The contract confirms a key subsystem supply chain for the SMR programme as it moves toward first-of-a-kind deployment.

Where this fits

This deal exposes a hard fact about nuclear supply chains: even the West's most advanced SMR programme sources essential safety systems from outside the Anglo-American sphere. Rolls-Royce is building the reactor vessel in the UK, but control rod drives will come from the Czech Republic. Australia has no domestic nuclear manufacturing base, no operating reactors, and no supply-chain relationships in the sector. If Australia were to deploy SMRs, or any reactor type, it would enter the market as a greenfield buyer with zero sovereign capability. That is not an argument against nuclear. It is an argument for building supply chains now, not after the ban is lifted and projects are already two years behind schedule.

What it means

Australia's electricity transition is locked into Chinese supply chains for panels, batteries, inverters and rare-earth magnets, with no domestic replacement path. Nuclear supply chains are fragmented across the West and Czech Republic, but they are at least diverse, non-rival, and open to new entrants with the will to build them. The Rolls-Royce SMR programme shows that small, modular reactors are moving from theory to industrial reality in jurisdictions that allow them. Australia's 1998 nuclear ban forecloses the option to build the supply relationships, skills and manufacturing we would need to participate in, or benefit from, that shift.
