Fruity Pebbles

Hey kids! Build a nuclear power plant, just like this:

The modules can be made in factories with high quality control, transported to a site, and assembled Lego-like into a power plant.

[...]

The "plug-and-play" approach to construction and the small size of the reactor could revolutionize how nuclear plants are built. "If this works, the economic obstacle to building new plants will be removed," said Kadak. If competitive, such small, modular plants will be attractive not only to the U.S. market but also to China and other rapidly developing countries that have widely dispersed populations.
