Hinkley Point C project to bring carbon-free electricity to six million UK homes

Over a six-year contract, Nexans will design and manufacture a total of 3,000 kilometres of cables developed to ensure safety, reliability and long life.

Hinkley Point C, under construction in the UK county of Somerset, marks a significant milestone in the revitalisation of the UK’s nuclear power sector. With two EPR reactors producing 3,200 megawatts of power for the national grid, the plant will be capable of supplying around six million UK homes with low-carbon electricity. This will make a major contribution to the UK’s move to net zero and will offset nine million tons of carbon dioxide emissions a year over the plant’s 60-year lifespan.

Oliver Dervout, Nexans Market Segment Director for Power Generation said: “We are very excited to be involved in this ground-breaking project for the UK’s nuclear power program. We have already gained considerable experience as a supplier of nuclear-qualified cables for EPR projects worldwide, such as Flamanville (FA3) in France and Taishan in China. Winning the contract for Hinkley Point C confirms our solid reputation in the nuclear segment. The key to our success is the ability to combine technical expertise, high level products and extensive industrial design and manufacturing capability.” 

Nexans is supplying a variety of custom-designed, nuclear-rated cables for the Hinkley Point C site, including medium voltage (MV) and low voltage (LV) power, control and instrumentation cables for pumps, valves, safety systems, power supplies and control room monitoring. They will be installed inside and outside of the nuclear containment area. It is vital that the cables continue to perform safely and reliably under the demanding environmental conditions corresponding to normal, accidental and/or post-accidental plant operating conditions. 

To satisfy the most rigorous safety standards, Nexans ENERGEN NUC halogen-free cables that comply with the Euroclass requirements for reaction to fire have been specified. They will be manufactured at the Nexans factory in Mehun-sur-Yèvre, France.
