The EDF Group’s Nuclear Operations business, which is the majority owner of the five operating and three decommissioning nuclear power plant sites in the United Kingdom, has released its annual update on the U.K. fleet. UK Nuclear Fleet Stakeholder Update: Powering an Electric Britain includes a positive review of the previous year’s performance and news of a billion-dollar boost in the coming years to maximize output across the fleet.

By all accounts the most productive nuclear power plant in British history, Somerset’s Hinkley Point B station closed for good on August 1, with the shutdown of its B1 unit, a 485-MWe advanced gas-cooled reactor. (The plant’s B2 unit, a 480-MWe AGR, was shuttered early last month.)

The station employed around 500 staff and 250 contractors and contributed approximately £40 million (about $48.7 million) per year to the Somerset economy, according to EDF Energy, owner and operator of the United Kingdom’s power reactor fleet.
