Heysham nuclear power station is operated by EDF Energy in Heysham, Lancashire, England. The site is divided into two separately-managed nuclear power stations, Heysham 1 and Heysham 2, both with two reactors of the advanced gas-cooled reactor (AGR) type. In 2010, the British government announced that Heysham was one of the eight sites it considered suitable for future nuclear power stations. On 1 August 2016, Heysham 2's Unit 8 broke the world record for longest continuous operation of a nuclear generator without a shutdown. This record-breaking run exceeds the previous record of 894 days set by Pickering Nuclear Generating Station's Unit 7 (Lake Ontario, Canada) in 1994. The reactor has generated 13.5 TWh of electricity so far[when?] during this continuous operation, taking its lifetime generation to 115.46 TWh.[clarification needed]
