One of the nuclear reactors at Heysham 1 nuclear power station in Lancashire has been taken out of service (Feb 6) for a major maintenance programme.
Around one thousand extra workers will join the site’s 700-strong team during the eight-week period, providing a boost to the local economy.
The team will carry out more than 12,000 separate pieces of work – each carefully planned during the last two years of preparation.
Heysham 1’s two reactors generate enough low carbon electricity to power around two million homes, so saving around six million tonnes of carbon dioxide emissions each year.
The extensive programme of work will see inspections inside the reactor, as well as the installation of new equipment at the plant.
The biggest projects include turbine and generator inspections and maintenance as well as replacing one large gas circulator that helps with cooling the reactor.
The maintenance periods, known as ‘statutory outages’, take place every three years on each reactor and are planned in advance with the National Grid to ensure that there is no impact on the national electricity supply.
Heysham 1’s other reactor is due to continue operating normally throughout the period.
In 2016 the power station saw its operating life extended until 2024.
