OVERVIEW OF THE HINKLEY POINT C EPR PROJECT ‘J0’ AND BEYOND

Published online: 22 February 2021
The twin unit EPR construction at Hinkley Point C is the first nuclear new build project to be undertaken in the UK in a generation. Moreover, it is now the country’s only new reactor project still in progress. The station’s two 1650 MWe plants  will complement the UK’s decarbonisedm energy mix with addition of approximately 7% of the current national requirement. In 2019, less than three years from the final investment decision, the ‘J0’ milestone was reached. This represents the end of the preparatory works, including all the common raft nuclear island concrete for Unit 1, enabling the upwards erection of the reactor containment and other support buildings. In addition to this, important milestones such as launch of the first tunnel boring machine, to tunnel the Unit 1 sea-water intake pipe have all been achieved. Over the coming years, the project will need to evolve in order to meet the increasing complexity and multi-organisation scope, which will present a challenging delivery environment. In order to support this, a UK-based Design Authority works on review, verification and acceptance of the HPC design including its UK specificities. This allows NNB, as licensee, to own its design and prepare the pre-commissioning safety case and operational strategies, defensible to the relevant UK regulators. As an example, this paper presents the roles and responsibilities in the Reactor Technology Team. This small, flexible team is involved in technical oversight of all aspects of the fuel & core design, through normal operations, anticipated and design-basis faults, severe accidents and radiological consequence estimation.
