The company hopes to build 16 of the plants, known as small modular reactors, and said each could power around one million homes.

Rolls-Royce, the British jet engine maker, said on Tuesday that it was forming a new business to build a series of smaller, cheaper nuclear reactors as Britain looks for ways to cut carbon emissions and to reduce the costs of nuclear energy, the New York Times reports.

The kind of reactor proposed by Rolls-Royce would cover about two soccer fields, or about one-tenth the acreage of a conventional nuclear power station, the company said.

These plants would generate less power — about one-seventh the output of the giant nuclear installation being built at Hinkley Point in southwest England.

But Rolls-Royce said it hopes to reduce construction costs to around £2 billion ($2.7 billion) each, compared to an estimated £22.5 billion for the Hinkley Point plant. Some of the savings would come from building a large number of plants and making modules in factories that can then be assembled at sites.
