Hinkley Point C achieves major milestone on schedule

16 June 2020

Workers building the Hinkley Point C nuclear power station have completed the 49,000-tonne base for the station’s second reactor on schedule. 

The final concrete pour of 8,991m3 set a new UK record for a single, continuous pour. It surpasses by 37m3 the previous record during the construction of the base for Hinkley Point C's first unit in June 2019.

The power station in Somerset will produce reliable low carbon electricity and – alongside renewable power - will help Britain move to a future without polluting fossil fuels.

This major milestone in nuclear construction was completed by teams who have had to adapt to new Coronavirus working conditions. Their achievement, known as “J-zero”, comes less than a year after the completion of the first reactor’s base in June 2019. It is the second major goal in 2020 and the successful completion of both follows the achievement of all the project goals in 2019. The date for achieving J-zero on Unit 2 was set more than four years, before the final investment decision was taken.
