The U.K. government has granted a development consent order (DCO) for EDF Energy’s proposed Sizewell C plant near Leiston in Suffolk, moving the new nuclear build project closer to a reality.

Nuclear New Build (NBB) Generation Company, an EDF Energy subsidiary, submitted the DCO application to the government’s Planning Inspectorate in May 2020, setting out the range of measures the project would implement to mitigate construction effects and maximize community benefits. The Planning Inspectorate accepted the application in June 2020 and completed its examination in October 2021. Recommendations were made to the secretary of state for business, energy, and industrial strategy this February.

The target date for the start of electricity generation at Hinkley Point C’s Unit 1 reactor has been moved back to June 2027, following the completion of a schedule and cost review of the new nuclear build project, EDF announced last week.

While the review considered the main aspects of the project to construct two 1,630-MWe EPRs in Somerset, England, the schedule and cost of electromechanical works and of final testing were not examined, according to the utility.

EDF Energy has made a “proactive decision” to move Britain’s Hinkley Point B power station into its defueling phase no later than July 15, 2022—some eight months earlier than previously scheduled—the company announced on November 19.

The two-unit plant, located in Somerset, England, began generating electricity in 1976 and has since produced more than 300 TWh of power, enough to meet the electricity requirements of every home in the United Kingdom for three years, according to EDF.

Horizon Nuclear Power is in talks with the U.K. government to revitalize plans to build the Wylfa Newydd nuclear power plant in northwestern Wales, the Financial Times reported last week.

The United Kingdom’s Office for Nuclear Regulation (ONR) issued an improvement notice to EDF Energy Nuclear Generation Ltd. earlier this month for a problem involving the pressure systems safety regulations (PSSR) at the two-unit Heysham 1 nuclear power station. The notice was served following an inspection of the Unit 1 pressure vessel at the Lancashire site.
