ENGLAND, UK - Two nuclear reactors at Hartlepool power station in County Durham, North-East England, have been closed as part of a $36.4 million maintenance program that will see more than 1,200 separate pieces of work done over a period of nine weeks.

One of the biggest projects will be replacing a generator transformer which increases the voltage in the site's electricity before it is sent to the grid.

The maintenance periods, known as 'statutory outages', take place every three years and are planned in advance with the National Grid to ensure that there is no impact on the national electricity supply, reports The Northern Echo.

Hartlepool's other reactor is due to continue operating normally.
