Most of the power units of nuclear power plants in Ukraine have a service life of at least 60 years.
"Most of our power units will work for at least 60 years, as we expect,"—said the Acting President of NNEGC Energoatom Petro Kotin during a press conference.
It makes no sense to plan the operation of power units for a long time, since by that time the construction of new nuclear power plants may become cheaper.
"As for 80 years. Perhaps by that time a decision will be made that it is cheaper to build a new power unit as a replacement than to invest in extending the resource of old capacities," he noted.
Reference. For WWER-1000 reactors the Ukrainian NPPs are equipped with, the design service life is set at 30 years. But the operation of this type of reactors can be extended for at least another 30 years.
Currently, 12 out of 15 power units of Energoatom have been operating for more than 30 years. Every 10 years, for each power unit, Energoatom prepares a "Report on Periodic Safety Reassessment (RPSR) of the Power Unit".
There are four nuclear power plants operating in Ukraine that include 15 power units. 13 of them are WWER-1000. Two more (RNPP-1 and RNPP-2) are WWER-440.
