ny_quant1. Rolls-Royce plans 16 mini-nuclear plants for UK
Each plant would produce 440 megawatts of electricity - roughly enough to power Sheffield - and the hope is that, once the first few have been made, they will cost around £2bn each.
The consortium says the first of these modular plants could be up and running in 10 years, after that it will be able to build and install two a year.
By comparison, the much larger nuclear plant being built at Hinkley Point in Somerset is expect to cost some £22bn but will produce more than 3 gigawatts of electricity - over six times as much.
2. Tiny Nuclear Reactors Can Save American Energy
Until now, customers only had one choice for nuclear, and that was a gigawatt-sized power plant. Now, we’re talking about reactors at the megawatt scale that can flexibly meet a customer’s energy needs as demand grows.
NuScale is the most conservative of the small-nuclear programs trying to reach the market. Their reactor design is a traditional light-water reactor, but smaller, simpler, and—according to NuScale—more scalable. The design eliminates coolant pumps, external steam generator vessels, and other equipment found in existing plants, so NuScale claims it’s cheaper to manufacture, lower-risk for operators, and easier to maintain.
The light-water design gives NuScale an edge in power among its tiny-reactor peers. While other companies are seeking approval for reactors that produce just a few megawatts of energy, NuScale’s design reaches 60 megawatts. For comparison, the smallest nuclear plant in the U.S. produces 600 megawatts, yet it's 100 times the size of NuScale's power module.
