Small modular reactors – a credible option

THE EDITOR, Madam:

I share Minister Vaz’s optimism about Jamaica’s oil prospects and support a balanced approach to our energy future. However, from an engineering standpoint, one core requirement must be addressed: the need for continuous, reliable, low-carbon power that is not dependent on weather conditions.

Solar and wind will continue to play an important role, but their output is inherently variable. To stabilise the grid and achieve emissions reduction at scale, Jamaica will ultimately require a firm, always – available power source. One credible option currently under active global development is Small Modular Reactors (SMRs). These compact nuclear plants are designed for incremental deployment, enhanced safety and consistent output. Based on Jamaica’s demand profile, a small fleet of approximately three appropriately sized SMRs, strategically located, could provide long-term energy stability while significantly reducing reliance on imported fuels. Refuelling cycles are measured in years rather than weeks, offering cost and supply predictability.

Although SMRs are not yet widely deployed commercially, this is precisely why early preparation is essential. Infrastructure planning must anticipate where technology will be in 10 to 15 years, not where it stands today. Delayed decision-making risks locking the country into outdated or suboptimal energy systems.

A key enabling step is legislative readiness. Section 27 of the Nuclear Safety and Radiation Protection Act (2015) should be amended to move beyond its current restrictive stance and explicitly allow for the licensing, construction and operation of civilian nuclear power facilities under strict regulatory oversight. Such amendments should establish clear frameworks for site approval, environmental safeguards, operator liability and long-term waste management.

In parallel, Jamaica should establish an independent nuclear regulatory authority with the technical capacity to oversee safety, compliance, public protection and knowledge transfer from overseas operators. Public education will also be vital to ensure informed national discussion.

Commercially, a Build-Own-Operate model – similar to Jamaica’s successful toll-road framework – offers a practical path forward. Under this approach, experienced international developers could finance, construct and operate the facilities, while Jamaica benefits from stable, long-term power purchase agreements without assuming significant upfront debt.

Jamaica need not commit today, but it must prepare today. A technology-neutral, forward-looking strategy will help secure true energy resilience for generations.
