How Westinghouse and Korea Carve Up the Nuclear Reactor Export Market

In January 2025, Westinghouse and Korea's reactor makers settled a years-long patent lawsuit over whether Korea's APR1400 design drew on Westinghouse-owned technology. The settlement lets Korea proceed with reactor exports to the Czech Republic and elsewhere. Westinghouse stated the terms would remain confidential, which the article interprets as a sign of a negotiated division rather than a clean victory for either side. The underlying dynamic is that Westinghouse controls design heritage while Korea controls a track record of on-time delivery.

Where this fits

This story bears on Australia's energy sovereignty and the speed of the firm-power transition. Western nuclear supply chains are fragmented, expensive and slow to scale; Korea has delivered reactors on schedule at lower cost. Any Australian nuclear program faces a choice between proven Korean capability and Western designs that have not built new units in decades. The settlement signals that both players will compete for export markets, which is healthy for buyers, but it also shows how thinly spread Western nuclear export capacity is, and how far ahead Korea has moved on manufacturing readiness.

What it means

Australia cannot assume Western nuclear vendors will be ready when a change in law allows new builds. Korea's export success (Czech deal, others in prospect) means Korean reactors will set the cost and schedule benchmark for any Australian tender. If Australia wants firm power to replace coal, and if law permits only nuclear, the realistic path runs through Korea, which means accepting reliance on a partner aligned with China on trade, and possibly ceding supply sovereignty to a non-Five-Eyes builder. That is the trade-off the settlement underlines: speed and cost against strategic autonomy.
