The Hinkley Point C power plant in Somerset is gargantuan. The 176-hectare (435-acre) plant will provide 3.2 gigawatts of power, enough for 6m homes. It is not just the project that is huge: the cost is as well. With a price tag that has ballooned to a reported £48bn, and delayed by at least five years, it has become a symbol of the pitfalls of nuclear power.
But a clutch of companies argue they have a quicker, cheaper option than large Hinkley-sized plants in the form of small modular reactors (SMRs), which can be built in a factory and then slotted together on site.
