What happened

Rolls-Royce SMR, CEZ and the Czech Ministry of Industry and Trade signed a memorandum of understanding to begin site-preparation activities at Tusimice and Detmarovice. The sites are in northern and eastern parts of the Czech Republic, respectively.

The work broadens the candidate site set beyond the first unit being pursued at Temelin. The stated ambition is for up to 3 GW of small modular reactor capacity.

Why it matters

The agreement is a concrete pre-construction step: it moves attention from one pursued location to three potential locations. That gives the Czech SMR programme a wider site pipeline while keeping its stated capacity ambition in view.

It also fits a related record of broader European SMR and advanced-reactor site development. On the same day, separate planning or pre-construction steps were reported in the United Kingdom and France.

Limit and next receipt

This memorandum does not commit the parties to build reactors. The record does not provide a construction schedule, final investment decision, approvals, site-selection outcome, or allocation of the stated 3 GW across the locations.

The next useful receipt would be a disclosed outcome from the site-preparation work, or a subsequent project decision that specifies which site will advance and on what terms.

What to watch

Watch for a formal follow-on decision identifying an advancing site, its scope, or a construction commitment.
