Assessment of Pre-Construction Safety Report

The Office for Nuclear Regulation (ONR) has published its assessment reports in relation to the assessment of a Pre-Construction Safety Report ("HPC PCSR 2012") submitted by NNB GenCorp for the Hinkley Point C licensed site in Somerset. The reports are produced below.

They include 19 individual reports plus a summary report. The summary report concludes that HPC PCSR 2012 is a significant step forwards towards producing a final PCSR for Hinkley Point C. Progress to date is consistent with ONR's expectations for this project. The next revision of the HPC PCSR will fully integrate the site-specific information with the final GDA PCSR generic material and other design changes arising from experience gained at Flamanville 3.
