Permission has been granted for a reactor at Heysham 1 to return to service following a nearly four month shutdown.

Heysham 1 Reactor 1 was shut down in August earlier this year as a precautionary measure following the discovery of a crack in a boiler spine.

Two reactors at Hartlepool will also be allowed to return to service. EDF Nuclear Generation Limited presented the Office for Nuclear Regulation with a safety justification for the return to service of Heysham 1 Reactor 2 and the two reactors at Hartlepool.

ONR completed an independent assessment of this justification and is satisfied that EDF has demonstrated the continued safe operation for these reactors.

EDF intends to present a separate safety justification for Heysham 1 Reactor 1 which will be subject to independent assessment and will require formal permission from ONR before the reactor can return to service. ONR will publish its Project Assessment Report outlining its decision in due course.
