V.C. Summer Nuclear Station in South Carolina answers meltdown questions | WCBD-TV 2

Fukushima is a boiling water reactor and in South Carolina we have pressure water reactors,” says Byrne.

In the invent of a reactor leak, he says the pressure system reduces the risk of a meltdown or releasing radioactive steam into the environment.

“This pressurizer which is something that boiling water reactors don't have, just maintains the pressure in the reacting cooling system,” Byrne explained during an animation of a breach scenario.

Even though the summer site has strategically- placed backup generators, the next reactors set to open in 2016 and 2019 don't rely on electricity to pump the large amounts of water necessary to prevent a meltdown.

“So it will flow by gravity from here, down into the vessel,” says Byrne.
