Electric|Olkiluoto’s repairs will take longer in the coming years, as TVO prepares for surprises.
The summary is made by artificial intelligence and checked by a human.
Maintenance work at the Olkiluoto nuclear power plant will take longer than expected in the coming years.
Voimala’s owner, TVO, is stretching the schedules to prepare for surprises during the repair work.
The change may affect the price of electricity, as the supply of electricity decreases during maintenance.
Olkiluoton in the coming years, the maintenance work at the nuclear power plant will take longer than expected, which may affect the price of electricity.
The power plant’s three units are serviced annually, and now the schedules are changing.
“The new scheduling method increases the stated duration of annual maintenance for all plant units”, reports Teollisuuden vima (TVO), which owns the plant. in its announcement.
Schedule estimates are based on experience from previous maintenance. In the updated estimates, provisions have been made for unforeseeable defect repairs, i.e. surprises that slow down the work in practice.
For example, last spring, the newest triple unit was under maintenance for 74 dayswhen the original plan was half as short.
Under maintenance is of general importance because at that time the availability of electricity decreases and it can increase the price of electricity. About a third of Finland’s electricity is produced by nuclear power.
Last spring’s extended maintenance lifted the price of electricity on the exchange to an exceptionally high level.
TVO’s goal is that only one unit should be serviced at a time. In the spring, due to stretching, we reached a situation where two units were serviced at the same time.
They try to schedule the maintenance for the spring summer, but last spring the newest triple unit was already repaired in March. According to TVO, the unit had then been in production for a year, and its fuel plan had been made for one year.
The same will happen again next year, as the unit will be serviced from March to the end of April. In the future, it should be possible to run it for 18–24 months straight.
TWO also told on Friday about the accident that happened at the power plant in June. Four employees was exposed to radiation in June due to human errors.
