Hinkley Point C Pre-Construction Safety Report

Hydrock's nuclear specialists are supporting the preparation of the pre-construction safety report for the design of Hinkley Point C – the first nuclear power station to be built in the UK for over two decades.

Hinkley Point C Pre-Construction Safety Report

In October 2014 Hydrock's specialist nuclear management business was appointed as the quality lead – and subsequently also as the safety report lead – on the preparation of the third version of the site-specific pre-construction safety report for Hinkley Point C nuclear power station in Somerset. The report is an integral part of the suite of safety reports intended to justify the safety of Hinkley Point C’s design throughout the plant’s lifecycle – from construction, installation and commissioning, through its full operating life, to decommissioning, including consideration of on-site spent fuel and radioactive waste management.

The third version of the report, which will update the safety case to reflect the latest reference design for Hinkley Point C, is one of the documents that will be submitted in support of the application to obtain consent for the start of safety-related construction of the nuclear island at the heart of the plant.

The report includes detailed information on safety requirements and objectives, the site’s characteristics, an explanation of the principles, codes and standards used in the design, the design and safety credentials of the structures, systems and components involved in the installation, and various safety analyses, including those for both normal operation and accident conditions.

As the quality lead and the safety report lead, we are helping to define the safety case’s requirements and objectives and to implement them. With responsibility for co-ordinating the production of a suite of safety documentation, we are also managing the progress of the safety report through the safety clearance route, including its Independent Technical Assessment and review by the Nuclear Safety Committee.

Leading on the development of the safety strategy, we delivered an associated briefing for key technical stakeholders and also supported technical teams with defining and refining the scope and direction of technical issues associated with the safety case.  

One of the key challenges on this project has been maintaining the quality of the documentation produced by multiple authors, balanced against timely delivery, as well as protecting the agreed scope and objectives of the safety case from ‘mission creep’ whilst also recognising and championing the inclusion of valid, important changes. We have played a leading part in the team that successfully handled the delivery, review and acceptance of over 300 items of documentation to date, driving them through to the production of a complete quality record and associated audit trail.

Our ability to explain the UK regulatory context to non-UK safety documentation authors unfamiliar with the UK approach and provide them with support has enabled us to make the best use of their significant knowledge and expertise whilst presenting their input in a way that will be meaningful and well understood – all of which has been critical to ensuring that we developed the safety case in the right direction.

Our work has ensured the ongoing development and delivery of the safety case required by the Hinkley Point C licensee, EDF NNB GenCo, on time, within cost and to the highest standards.
