Summary
AlphaTech’s molten salt reactors measure roughly five feet wide and seven feet tall but can generate 12 megawatts each—enough electricity to power about 12,000 homes. “These are not massive plants,” Memmott says. “They’re compact, modular, and designed to be produced in a factory, shipped by truck or even a C-17, and assembled on site in about two days.”
A single reactor plant occupies just 30-by-30 feet, but up to 100 units can fit on a seven-acre facility, collectively generating 1.2 gigawatts. By designing these reactors to sit underground, AlphaTech maximizes shielding, isolates operations from public exposure, and safeguards against aircraft incidents.
Molten salt isn’t just fuel—it’s a versatile medium for heat and energy. Exiting the core of the reactor at 650°C, the coolant retains temperatures above 550°C even after generating electricity, enabling high-temperature industrial applications like chemical manufacturing, desalination, and district heating. “By the time the temperature drops to 70°C, the heat can be diverted to above-ground facilities, leaving almost no energy wasted,” Memmott explains.
