The short annual outage of Unit 2 lasted 25 days and was completed on
In addition to the normal periodic maintenance work and refuelling, tasks related to maintenance and continuous improvement were carried out on both units during the annual outage. The periodic inspection carried out every eight years was performed during Loviisa 1's extensive annual outage; the inspection covered, e.g., the reactor pressure vessel and its inner parts, and pressure tests were performed on the primary and secondary circuit's pressurised equipment and pipelines. Also a containment leak test, lasting about two days, was carried out. In conjunction with the annual outages, about one quarter of the fuel in both units was replaced.
This year, two main generator stators were replaced to more efficient ones. During 2014 - 2020 all main generators, busducts, switches and main transformers have been replaced at Loviisa.
'With all the works completed in the outages, we ensure safe and reliable operation in the future. It's a great achievement that, in spite of the challenging and exceptional conditions, we succeeded in performing all the planned annual outage works,' says Loviisa power plant's Deputy Director
'This demonstrates the exceptional commitment of our own and our subcontractors' employees to the quality implementation of the annual maintenance work and achievement of our common goal,' he continues.
In addition to the 500 power plant employees who participated in the annual outage, there were also nearly a thousand external workers. Some 75 per cent of the workers were Finns.
