‘Significant milestone for nuclear sector’ as Hunterston B relicensed for decommissioning

 The Office for Nuclear Regulation (ONR) has approved the relicensing of
the Hunterston B nuclear power station, ushering the North Ayrshire site
into its formal decommissioning phase.

From 1 April, Nuclear Restoration
Services (NRS), a subsidiary of the Nuclear Decommissioning Authority
(NDA), will take on full responsibility as site licence holder, replacing
EDF, which operated the Advanced Gas‑Cooled Reactor (AGR) until it ceased
generation in January 2022 after 46 years in service.

This first phase of
decommissioning work at Hunterston B, on the Firth of Clyde, will involve
the removal of all buildings and plant from the site, with the exception of
the reactor buildings and some adjoining structures which will be modified
to create a Safestore structure.

This Safestore is designed to maintain the
reactor buildings in a safe state through the Quiescence phase of around 70
years. Following this, the final site clearance phase will involve the
removal of the reactors and debris vaults housed in the Safestore
structure, making the site available for future use.
