Small nuclear reactors: Big potential for Singapore, but with caveats

MINI nuclear reactors, also known as small modular reactors (SMRs), could unlock clean energy in Singapore. But there are several challenges that policymakers will need to navigate: from costs and supply-chain complexities to geopolitics.

On Jul 31, Singapore inked a 30-year deal with the US to study SMRs and other advanced nuclear-power technologies. The deal, called a “123 Agreement”, gives Singapore access to technical information that is under US export control.

The timing of the deal comes as hype builds around SMRs and their potential to spark a nuclear-energy renaissance.
