Olkiluoto 3 coughed again, is there reason to worry about repeated problems? According to the professor, the trial run has progressed well

Industrial Power (TVO)’s new nuclear reactor’s electricity production was interrupted on Saturday. The facility is still in trial use. TVO said the reason was a turbine failure. Now Olkiluoto 3 is operating again with a power of more than 1,400 megawatts.

It was not the first time that the power plant had to be repaired. A month ago, the triple reactor suffered a turbine failure. On September 8, during the test run, a fault was noticed in the safety valve, which led to a momentary power shortage.

At the end of August, a measuring error in the generator’s voltage regulator was fixed. At the same time, automation upgrades were also made to the facility.

In June, the trial run was interrupted due to problems with loose parts in the turbine. At the end of April, when the plant was being run down according to the trial operation plan, its boron pumps started unexpectedly.

After that, Teollisuuden Voima announced that regular electricity production will only start in September instead of July.

In addition, TVO has said that the supply water pump that was on standby at the plant has been repaired.

According to Teollisuuden Voima, these are normal problems related to trial use.

The manufacturer’s largest turbine

Professor of energy technology at Lappeenranta–Lahti University of Technology (LUT). Juhani Hyvärinen according to the trial use has gone well.

“Test operation is done because calculations do not allow you to find out with certainty how the plant works. A few downtimes that have resulted, for example, from the fact that some protection has tripped or a part of the turbine plant has broken are completely normal.”

Actually, according to Hyvärinen, there have been surprisingly few problems.

“When you consider that the Olkiluoto turbine is the largest that the manufacturer in question has made, now this has gone really well. There are minor equipment faults, even though the equipment and systems have already been tested separately. You don’t drive from the factory when it’s cold.”

The industrial force estimates that normal production of 1,600 megawatts will start in December. The problems that occurred during the trial operation of Hyvärinen do not predict the transfer of production. When the plant runs at full capacity, it covers about 14 percent of Finland’s electricity needs.
