Hunterston nuclear reactor offline due to seaweed level

A reactor at the Hunterston B nuclear power station in Ayrshire has been taken offline due to high levels of seaweed in the waters around the plant.

The plant relies on water taken from the sea for cooling.

Operator EDF Energy said the shut down at 18:40 on Monday was a “precautionary measure” with “no health, safety or environmental impacts”.

It said the station’s second reactor was continuing to operate, but at a reduced load.

In a letter to stakeholders, station director Colin Weir said: “Hunterston B power station’s reactor 3 was manually shut down at 18.40 on Monday 1 June due to severe seaweed ingress, accompanied by strong winds and storm surges.

“This was done as a precautionary measure when it was clear that the seaweed levels weren’t reducing.

“Reactor 4 was also reduced in power and remains operating at a reduced power.”

Mr Weir said staff at the station were monitoring the weather and seaweed levels would begin the return to normal service when it was determined conditions were “in a stable state”.
