Loviisa Nuclear Plant Refueling and Maintenance Outage to Begin

Fortum Plans Upgrade at Loviisa Nuclear Power Plant

Fortum will soon start the annual refueling and maintenance outage at its Loviisa nuclear plant in Finland.

The Unit 1 outage is set to begin August 7, followed by servicing of Unit 2. Unit 1 will undergo the extensive inspection outage performed every four years and Unit 2 is scheduled for a so-called short refueling outage. The entire outage procedure is estimated to be finished in eight weeks.

At Loviisa 1, reheaters and safety valves in the initial steam line will be replaced. At Unit 2, the generator’s rotor will be replaced and major overhaul of stator conducted. One quarter of the fuel will be replaced. In addition to normal periodic maintenance tasks and refueling, the most significant work on both units this year is the modernization of high-pressure turbines and replacement of main transformer and generator breaker.

A total of 950 external contractors are involved in Loviisa’s annual outage and ongoing modernization projects. There are approximately 500 Fortum employees and some 100 permanent contractors working at Loviisa.
