UK Regulators Complete Step 2 Review of GE Vernova Hitachi's BWRX-300 Reactor Design
GE Vernova Hitachi Nuclear Energy's BWRX-300 small modular reactor design has completed Step 2 of the U.K. government's generic design assessment. This regulatory milestone confirms that no fundamental safety, security, or environmental issues were identified that would hinder further assessment stages.
The U.K. Office for Nuclear Regulation, along with the Environment Agency and Natural Resources Wales, noted that the review is a voluntary, non-site-specific examination of reactor designs. Completion of Step 2 indicates that the developer's submissions are sufficiently mature for further engagement.
Step 2 focuses on design concepts and organizational readiness rather than detailed technical analysis. A future Step 3 review would involve in-depth scrutiny of safety cases and environmental impacts. Currently, there are no identified sites or deployment proposals for the BWRX-300 in England or Wales.
