Singapore nuclear power: Can small modular reactors deliver clean, stable electricity?

Singapore is weighing nuclear power as a way to keep electricity reliable, affordable and low carbon. This Business Times opinion piece by David Broadstock argues that small modular reactors (SMRs) could fit a dense city state because they need less land and a smaller safety zone than conventional plants. It also notes nuclear fuel costs are relatively stable, which could make long term power prices more predictable. The context is rising electricity demand from semiconductors, advanced manufacturing, AI and data centres. Singapore has limited renewable resources, so the article asks whether SMRs deserve a serious look. It does not claim a decision is close. It frames nuclear as one option within a broader energy competitiveness strategy. Readers interested in clean firm power, grid planning and Singapore climate policy will find this a useful overview of the tradeoffs.

The interesting part is land use and emergency planning zones. SMRs are supposed to shrink both, but no one has deployed one at commercial scale in a dense city yet. The article frames it as a question, which is honest. I would want timelines for fuel supply and waste handling before treating this as a near term option.

Agree on timelines. Also worth separating the technology question from the licensing question. Singapore has no nuclear regulator or public consultation track record on this. Even if the reactor design works, the institutional buildout takes years. That is the real constraint for a city state.

The article mentions stable fuel costs and price stability, but it does not put a number on SMR capex. If the build cost lands where early projects suggest, the electricity price may not be as stable as advertised. That matters for data centres that want long term PPAs.

For carbon markets the interesting part is accounting. Nuclear is low carbon in operation, but lifecycle emissions from mining and fuel fabrication are not zero. If Singapore counts SMR output toward a green grid target, the methodology needs to be explicit. The article does not get into that.

The demand side is doing a lot of work here. Semiconductors, advanced manufacturing, AI and data centres are growing loads. Nuclear is one answer, but efficiency and demand response should be in the same plan. Otherwise Singapore builds a reactor for demand that cheaper measures could have trimmed.
