The Science Behind It Conventional nuclear power plants circulate water through a reactor core, where it is heated and then passed via pipes to larger vessels, where it converts to steam.

«All the designs for small modular reactors eliminate the features in larger plants that can contribute to a potential accident,» he says.

Moreover, there are «very real and specific dangers of nuclear energy,» including the reactor's «potential for massive destruction in an immediate danger,» plants are potential terrorist targets, plants provide «the means and excuse» to build nuclear bombs, and they create wastes that persist for thousands of years, and uranium mining causes lung disease and large volumes of wastes.

Scott Burnell, public affairs officer at the NRC, said NuScale's application is the first to propose a nuclear power plant designed with several small reactors instead of one large one.

The NuScale Power Module ™ and power plant design enhances the intrinsic physical protection and security of the plant through the elegantly simple design, elimination of large break loss of coolant accidents, and full reliance on passive systems to cool the reactors and spent fuel for extended periods without the need for AC power, DC power or additional water following an upset condition.

The size of the reactor's nuclear core is a fraction of those of large conventional nuclear power plants, with an attendant small radioactive source term.

Response: Despite the small land area of the plant, SMR - 160 will accrete a small fraction of the dose of a large contemporary reactor at its site boundary because of the many dose mitigation features built into its design, viz:

In the SMR - 160 power plant, the inventory of fuel in both the pool and the reactor is a fraction of that in large reactors, and that entire fuel inventory is kept cool without any reliance on pumps and motors.

Some blamed the outage on «human error» at Taiwan's largest natural gas plant, but the gap between supply and demand was almost identical to the amount of power provided by Taiwan's shuttered reactors.
