The United Kingdom’s Office for Nuclear Regulation (ONR) has granted permission for the start of bulk mechanical, electrical, and HVAC component installation work at the Hinkley Point C site in Somerset, England, where two 1,630-MWe EPRs are under construction. Thus far, most of the activity at Hinkley Point C has been in the field of civil construction.

This new phase, according to ONR, will require a workforce of up to 4,000 during peak times, including welders, pipe fitters, and electricians. The work is to be accomplished over a three-year period, with NNB Genco—the EDF Energy subsidiary set up in 2009 to build and operate Hinkley Point C—teaming up with four suppliers: Balfour Beatty Bailey, Doosan, Cavendish, and Altrad.

The UK SMR consortium last week revealed the latest design and power upgrade—from 440 MW to 470 MW—for its proposed small modular reactor. According to the consortium’s lead company, Rolls-Royce, the “refreshed” design features a faceted roof, an earth embankment surrounding the reactor to integrate with the landscape, and a more compact building footprint.

EDF Energy has received approval from the United Kingdom’s Office for Nuclear Regulation (ONR) to restart the Hunterston B power station’s Unit 3 for a limited run, according to August 27 announcements from both the company and the regulator. EDF has permission to operate the unit for up to 16.425 terawatt days (approximately six months of operation), the ONR said.

EDF also announced that Hunterston B—located in North Ayrshire, along the western coast of Scotland—will begin its defueling phase no later than January 7, 2022, more than a year earlier than the expected retirement date of March 2023. The decision, EDF said, was made following a series of executive board and shareholders meetings.
