Torbjörn Wahlborg, Chairman of the Board of Ringhals AB and Head of BA Generation at Vattenfall, explained that the decision to decommission Ringhals 2 in 2019 and Ringhals 1 the year after that was based on the analyses carried out by Ringhals over the summer.
The analyses considered factors such as fuel costs, future maintenance requirements and any investments that would be required in order to run the reactors until 2020, and requirements in terms of skills and resources.
The factors that influenced the timings for decommissioning of the reactors were fuel economy and technical separation of the systems shared by both plants.
"We believe it was absolutely essential to take the decision now, so Ringhals can undertake detailed planning, to optimise the costs of both investments and maintenance," said Torbjörn Wahlborg to the news agency TT.
Minority owner E.ON would have preferred the analyses to continue before a decision on decommissioning was made.
"But the meeting has reached a decision and it is one we will have to abide by," said Louise Gudmundson from E.ON's press department to news agency TT.
It will have an impact
Torbjörn Wahlborg also told TT that it is too early to say how the decision will affect employees.
"This will be a fairly lengthy process but clearly, in the long term, it will affect the workforce. A lot of those currently working at the plant are consultants and contractors. So it's too early to say exactly how this will affect our own employees."
Earlier this year, Vattenfall wrote down the value of Ringhals by 17 billion kronor.
"There won't be any need for further impairments because we've already written down the entire value of Ringhals 1 and 2," said Wahlborg.
As far as Ringhals 3 and 4 are concerned, the existing plans, which provide for both plants to remain in operation for 60 years, will remain unchanged.
