Reactor 1 at the aging Wylfa Magnox nuclear plant has been shut down since early January, reports said. While the original shutdown was for maintenance purposes and was planned to last 100 days, restart has been delayed twice due to issues arising during the maintenance process.
Among the problems were a turbine and a gas circulator in need of repair, both discovered when plant staff attempted a restart during the Easter holidays. In addition, a damaged and leaking pipe was found on 13 June.
According to the BBC, a Wylfa spokesman said no radioactive material was involved in the incidents.
While the 43-year-old plant is scheduled to close late this year, an extension to December 2015 is possible if it can pass safety checks. Once it is back online in an estimated two weeks, the plant is scheduled to produce power until September of this year.
A second reactor at the plant was shut down in April 2012 after 41 years in operation.
Plans are in the works for a new, £8bn ($13.6bn) nuclear power station to be built by the Wylfa plant’s owner, Horizon Nuclear Power, on a nearby site. Horizon, a Hitachi subsidiary, says it aims for the new Wylfa Newydd plant to come online before 2025, with construction to begin in 2018.
The new plant will feature two Advanced Boiling Water Reactors, which are planned to generate a minimum of 2.7 GW.
