Official nuclear energy policy in the Western countries with little investments and continuously changing requirements has, with time, pushed into bankruptcy most of the major actors. The only left suppliers are GE Hitachi Nuclear Energy, which is on the verge of bankruptcy and has been in this status for quite some time, and Areva which produces the bloated and expensive EPR. There are some smaller actors, but they are eternally locked in the study phase, they have no commercial scale proposals.
As a result the Russian state company Rosatom has become the world's major supplier of services and plants with many currently under construction. Trouble is that this is power, but not just electrical power, it is also political power, this situation gives Russia a lot of leverage in addition to the more publicised leverage they get from gas supplies. Moreover, they have this leverage also in a few NATO countries and it keeps growing since Hungary recently approved the extension of their only nuclear power plant. It is difficult to blame Hungary since they had little choice, but it means that the Russians will have under direct control for decades almost half of the electricity supplied to Hungary in addition to oil and gas supplies.
Adding to the loss of political leverage there is even the loss of the ability to influence future technologies. While generation IV reactors are becoming like nuclear fusion, the eternal promise that will never be fulfilled the world is stuck with the PWR technology that produces a lot of nuclear waste. So even from this point of view the overall impact seems negative.
Did the Western world choose a nuclear energy policy that totally backfired or am I only seeing the negative aspects of the situation?
