List of Nuclear Power Stations in the UK An Overview

The United Kingdom has been a pioneer in nuclear energy, utilizing it as a significant part of its electricity generation mix for decades. Nuclear power stations in the UK contribute a substantial portion of the country’s low-carbon electricity, helping to meet energy demands while reducing greenhouse gas emissions. This article provides a comprehensive list of nuclear power stations in the UK, highlighting their locations, capacities, and operational status. Whether you are a student, an energy enthusiast, or simply curious about the UK’s nuclear infrastructure, this guide will offer valuable insights.

Sizewell B Nuclear Power Station

Located in Suffolk, Sizewell B is the only pressurized water reactor (PWR) in the UK, making it unique compared to other UK nuclear plants which primarily use advanced gas-cooled reactors (AGRs). Commissioned in 1995, Sizewell B has a generating capacity of approximately 1,198 megawatts (MW). It plays a crucial role in providing reliable, low-carbon electricity to the national grid.

Hinkley Point B Nuclear Power Station

Hinkley Point B, situated in Somerset, is one of the UK’s oldest operational nuclear power stations. It is an advanced gas-cooled reactor with a capacity of around 1,090 MW. Despite being commissioned in the 1970s, Hinkley Point B remains a vital energy source, although it is scheduled for decommissioning in the near future.

Heysham Nuclear Power Stations (Heysham 1 and Heysham 2)

Heysham hosts two separate nuclear power stations: Heysham 1 and Heysham 2, both located in Lancashire. Heysham 1 consists of four AGR reactors with a combined capacity of about 1,260 MW, while Heysham 2 has two AGR reactors producing approximately 1,240 MW. Together, they contribute significantly to the UK’s nuclear output.

Torness Nuclear Power Station

Located in East Lothian, Scotland, Torness is an advanced gas-cooled reactor power station with two reactors generating a total of roughly 1,200 MW. Commissioned in the mid-1980s, Torness is one of the most modern AGR stations and continues to provide substantial low-carbon electricity to the UK grid.

Dungeness Nuclear Power Stations (Dungeness A and Dungeness B)

Dungeness A, located in Kent, was the UK’s first commercial nuclear power station but has been shut down since 2006. Dungeness B, also in Kent, consists of two AGR reactors with a combined capacity of about 1,090 MW. However, Dungeness B is currently in the process of being decommissioned due to aging infrastructure.

Hunterston B Nuclear Power Station

Hunterston B in North Ayrshire, Scotland, features two AGR reactors with a combined capacity of approximately 1,000 MW. It has been operational since the 1970s but is approaching the end of its operational life, with plans for decommissioning underway.

Hinkley Point C (Under Construction)

Hinkley Point C is the newest nuclear power station under construction in Somerset, intended to replace older stations such as Hinkley Point B. It will feature two European pressurized reactors (EPRs) with a combined capacity of 3,200 MW. Once completed, Hinkley Point C is expected to provide low-carbon electricity for around six million homes.

The UK’s nuclear power stations play a critical role in the country’s energy landscape, providing a significant portion of low-carbon electricity. From the operational AGRs at Heysham and Torness to the unique PWR at Sizewell B, these plants have helped the UK reduce its carbon footprint while ensuring energy security. As older stations like Dungeness B and Hunterston B reach the end of their operational lives, new projects such as Hinkley Point C are set to take their place, ensuring the continued presence of nuclear power in the UK’s energy mix. Understanding the list and status of these nuclear power stations is essential for anyone interested in the future of energy in the United Kingdom.
