Question to the Department for Environment, Food and Rural Affairs:

To ask His Majesty's Government what generic design assessments the Environment Agency are currently undertaking; and when they expect each of those assessments to be completed.

The Environment Agency is currently carrying out two Generic Design Assessments (GDA). Holtec’s SMR 300 is currently undergoing a 2 step (Fundamental Assessment) GDA that is planned to be completed in March 2026. Rolls Royce SMR’s design is currently undergoing a full 3 step (Detailed Assessment) GDA. Rolls Royce SMR and the Environment Agency are targeting completing the GDA in 2027. We understand that Rolls-Royce SMR will provide further information to the public around the time of contract award by Great British Energy-Nuclear.
