Haiyang units 5 and 6 receive construction licences with different first-concrete conditions
The 29 October licences were published on 30 October; unit 6 still requires release of a first-concrete hold point.

The story explained
China’s National Nuclear Safety Administration published construction licences for Haiyang nuclear units 5 and 6 on 30 October. Issued on 29 October to Shandong Nuclear Power Third Nuclear Energy Co., they establish regulatory permission for construction rather than confirming concrete placement at both units.
Following an inspection, the regulator found unit 5 ready for its first nuclear-island foundation concrete and authorised that work. Permission to proceed does not establish that the pour has occurred.
Unit 6’s first nuclear-island concrete remains a hold point supervised and released by the North China nuclear and radiation safety office. Main-pipeline welding is also a hold point at both units; the associated work cannot proceed before release.
Licences 2622 and 2623 expire on 28 October 2036. The operator must implement quality assurance, control design and site changes, and oversee participating organisations. The expiry dates are not commissioning targets, and the notice does not identify valve or actuator awards.
Why it matters
Editorial analysis: The licences establish a construction milestone, with nuclear equipment quality assurance, traceability and installation interfaces governed by regulatory hold points.
