The reactor EPR is a project of nuclear reactor with third generation pressurized water conceived(designed) and developed by Areva during 1990s and 2000. Four type(chap) EPR's reactors are under construction. The construction of these reactors planned in 5 years are begun for 10 and 8 years and are still far from being finished. And the costs of construction multiplied by three at least.
Is it necessary to continue to invest(surround) in nuclear power?
