1. Jamaica’s Small Modular Reactor discussion should not be reduced to fear of radiation. The more immediate danger is a poor country being invited to make a rich-country bet, using borrowed money, immature supply chains and institutions still struggling with ordinary infrastructure. SMRs may be technologically interesting. That does not make them Jamaica’s wisest energy investment.

2. Start with scale. Jamaica’s record electricity demand reached 692 megawatts on 12 July 2023, after a previous record of 666 MW in 2017. Against that background, a single 100–300 MW nuclear unit would represent about 14–43 per cent of Jamaica’s all-time peak demand. That is not a small addition to a small island grid.[jpsco]

3. The June 5 island-wide blackout should therefore be treated as a diagnostic event. It showed that Jamaica’s energy problem is not merely generation; it is resilience. A nuclear reactor cannot trim vegetation, harden poles, underground critical feeders, modernise relays, train line crews, reform dispatch discipline, provide black-start capability, or repair weak transmission and distribution systems.

4. The financial exposure is darker still. Even optimistic SMR advocacy assumes a long road: licensing, site selection, environmental assessment, regulatory build-out, security design, emergency planning, grid upgrades, sovereign uranium fuel arrangements with states such as Kazakhstan, Canada, or South Africa, waste provisions, extensive overseas technician training, decommissioning funds and financing costs. For Jamaica, the question is not whether Canada, Britain, America or France can discuss nuclear power. They already possess deep nuclear ecosystems. The question is whether Jamaica should assume billions of dollars in direct or indirect risk before fixing cheaper, faster, known weaknesses.

5. Opportunity cost is the cruellest arithmetic. Every billion dollars placed behind SMRs is a billion not placed behind grid automation, utility solar, rooftop solar, battery storage, wind, vertical-axis wind where appropriate, small hydro, pumped storage, distributed generation, energy efficiency, demand response, microgrids, biomass, biogas and overseas technician training. Those alternatives are not fantasies. They match Jamaica’s size, climate, skills base and need for resilience.

6. Expert concern about SMR economics is not “bad mind”. The Institute for Energy Economics and Financial Analysis described NuScale’s long-running SMR effort as “too late, too expensive, too risky and too uncertain”. NuScale’s flagship Carbon Free Power Project in the United States was later terminated after cost concerns and insufficient subscription by participating utilities. That does not prove every SMR will fail. It proves Jamaica should not accept vendor optimism as national policy.[aljazeera]

7. Even the more sympathetic case for SMRs admits an economic condition Jamaica cannot ignore: SMRs must reach sufficient scale to become cost-competitive with other energy sources. In plain English, the promised price reductions depend heavily on repeated factory production, mature supply chains, standardised deployment and many customers. Jamaica would not be buying a mature consumer appliance. It could become an early customer in a global experiment whose final economics remain rather unsettled.[moneymediaja]

8. The regulatory burden is also formidable. Nuclear power requires an independent, technically strong regulator able to govern the whole life cycle: design, site approval, construction, operation, waste management, decommissioning and accident response. That is not ceremonial. It is the institutional foundation of civilian nuclear power.[jamaicaobserver]

9. Waste is another unromantic reality. SMRs may require less frequent refuelling than conventional reactors, and some designs advertise long operating cycles. But “less frequent” is not “no waste”. Spent fuel and radioactive materials still demand accounting, storage, transport security, safeguards, monitoring and eventual disposal. Jamaica has no deep geological repository, no national nuclear waste tradition, and no large cadre of nuclear materials professionals. The burden would outlive today’s politicians.[bloomberg]

10. The sovereignty issue is subtler but serious. Nuclear systems bring fuel relationships, export controls, safeguards, inspections, security protocols, vendor dependence, foreign training pipelines and diplomatic expectations. A country may begin by seeking energy independence and end by discovering that its electricity strategy depends on foreign licences, foreign technicians, foreign spares, foreign fuel and foreign geopolitical stability.

11. The Jamaica-Canada nuclear memorandum of understanding, signed in October 2024, confirms that this is no longer JB rum-talk or academic curiosity. Once formal pathways are opened, momentum can develop before citizens understand the national balance sheet. Democracies do not require citizens to prove corruption before asking questions. Democracies require public officials to provide satisfactory answers before committing taxpayers to enormous risks.[our]

12. The Caribbean geography adds another layer. Jamaica is a seismically active, hurricane-exposed, water-stressed island with limited evacuation depth and a compact grid. A nuclear incident need not resemble a Hollywood disaster to be nationally damaging. Even a prolonged outage, security event, fuel delay, cooling-water controversy, regulatory dispute, or loss-of-confidence episode could frighten investors, impair tourism, increase insurance costs and distract the government for years.

13. The deeper danger is psychological. SMRs tempt politicians, technocrats and business elites with the romance of one grand machine. But Jamaica’s problem is not the absence of a magic machine. It is the accumulated failure to perform unglamorous tasks consistently: maintenance, vegetation management, procurement discipline, engineering training, data transparency, tariff reform, regulatory seriousness and long-horizon planning. Nuclear power does not forgive weak institutions. It exposes them.

14. There is a better ordering of national effort. First, publish transparent grid data. Second, harden transmission and distribution. Third, accelerate proven renewables and storage. Fourth, develop biomass, biogas, small hydro and demand-side management. Fifth, build black-start and microgrid capability for hospitals, ports, water systems, schools and emergency services. Sixth, train technicians as if national survival depends on them, because it does.

15. The really dark sides of SMRs for Jamaica are therefore not inside the reactor vessel. They are in the debt ledgers, procurement rooms, regulatory gaps, foreign dependencies, opportunity costs and institutional weaknesses that may accompany the project long before any reactor produces a kilowatt-hour. Jamaica does not need to prove that SMRs are evil. It needs only to ask whether they are the best, fastest, least risky and most sovereign path to affordable, reliable power.

16. On present evidence, the answer is no. Jamaica should not mortgage its energy future to nuclear imaginings while practical resilience remains undone. Stop the cooing romance. Count the megawatts. Count the dollars. Count the years. Count the institutions required. Then ask whether this small island should chase the world’s most complex energy technology before mastering the systems already in its hands.
