Moreover, he said, most of the new reactors would be built on the same sites
as current reactors.
Well before the first 20 - year relicensing period ends, power plant owners will have to know what new components and equipment upgrades will be required to extend the lives
of current reactors to 80 years, and how high the costs and regulatory hurdles will be, before deciding whether to take that route or decommission the plants and shutter them, industry officials say.
That may mean advanced nuclear power can not contribute much to efforts to combat climate change in the near term, which
leaves current reactor technology as the only short - term nuclear option — and one that is infrequently employed at the global scale at present.
SMRs — «small» because they generate a maximum of about 30 percent as much power as
typical current reactors, and «modular» because they can be assembled in factories and shipped to power plant sites — have been getting a lot of positive attention recently, as the nuclear power industry has struggled to remain economically viable in an era of flat demand and increasing competition from natural gas and other energy alternatives.
As such, the closure is symbolic of the broader woes of the nuclear power industry in the United States, which has been unable to build new reactors and is seeing
the current reactors being shuttered, one by one.
«4th - Generation» reactors, currently in the research stage (e.g. the Integral Fast Integral Breeder Reactor), potentially have few of the major problems of
the current reactors.
SMRs feature smaller, less robust containment systems than
current reactors.
When you combine the largest radioactive inventory of
all current reactor designs together with the largest stored energy in highly reactive sodium metal coolant, you have the potential for a LARGE accident.
