For the last few years I’ve been following the bureaucratic twists and turns that the company NuScale has been following in Amercia as it tried to get approval for a new type of nuclear reactor.

As smart and as sensible as their approach seemed I did wonder if they’d ever make it through or whether this would turn into yet another case of a startup company bankrupted by the government.

It would seem not. US regulators will certify first small nuclear reactor design:

On Friday, the Nuclear Regulatory Commission (NRC) announced that it would be issuing a certification to a new nuclear reactor design, making it just the seventh that has been approved for use in the US.

But in some ways, it’s a first: the design, from a company called NuScale, is a small modular reactor that can be constructed at a central facility and then moved to the site where it will be operated.

That’s what so unique and clever about this machine. It’s built in a factory, shipped to where the power is needed and, when the fuel is exhausted, shipped back to the same factory where it is disassembled, the nuclear fuel re-processed, with unused fuel recovered and radioactive by-products stored. Much of each machine can also be re-used for new reactors.

Aside from this rather clever, holistic concept, these reactors are also designed to be passively safe: no operator actions are necessary to shut the reactor down if problems occur. Having said that it’s not as clever as things like Molten Salt Reactors (molten uranium salts as the reactor fuel); it’s still has uranium rods, control rods and boiling water as the energy transport mechanism.

Still, the whole “Buy it, install it, run it, return it when used” may make a difference in a lot of places around the world.

But not New Zealand I’m sure. Imagine what Lucy Lawless would have to say. Mind you, multi-millionaires, especially the frivolous creatures of Hollywood, are freed from the cares of much of the rest of the world, which is why she’s so keen on growing vegetables in Remuera.
